    Hi Sujith,

    I am new to Flex and ActionScript world, I am basicall a java programmer, I have read to some extent about Flex and used the examples on the adobe sites. I have tried BlazeDS as well. Though I was able to run the example in the tutorial, it was rather a simple example. I am trying to map a Java Object which is complex, and Object that has more objects inside it and those objects have some objects and so on.. to a certain level, how Can I map such complex types to action script objects. Can you please provide me with a working example if ppssoible.

    Your help will be greatly appreciated

    Hi Chandu,
    Lets say you have an object Student which contains properties named Address, Courses and Profile. All the three properties are different objects of respective Class types. When you are passing a object of the type Student to the Flex application, it will contain objects of the type Address, Courses and Profile right? In order to get all these objects mapped to your AS objects, all you have to do is to create AS objects of the type Address, Courses and Profile and map them to the respective Java classes individually. This applies, even if you are passing the objects in a ArrayList from Java; You will receive them as ArrayCollection, with the objects converted into mapped AS object :)
    Hope this helps. If not let me know, i will try to give you a sample :)

    Thanks for your prompt reply. I will try out your suggestions. But if you can provide me a sample if you get time, that will be great too.

    Thanks a Lot again.

    Hi Sujith,

    Can you please provide and example, say something like you mentioned.List of Students , I want to be able to have a page display list of students with their names courses they are taking etc, but this data should be retrieved from the Java Class,

    In this scenario, where does the Action Script fit. I mean my understanding is
    1) I will create a flex app i.e mxml file which will invoke the Java class like you described in one of your blog posts. But now to interpret the complex Object type returned by the java class I need Action Script objects to map to Java Objects,,…

    2) I will also write the java class and put the classes in the WEB-INF folder etc

    3) I will click a button to get the data from the page

    In the above scenario,,,
    a) where exactly will I need to create .as file mapping,
    b) which folder should the .as file reside in
    c) how will the client flex map know to render the data in a grid, table or text area etc

    The above are some areas I am still in dark.

    Your help will be greatly appreciated

    Hi Sujith,

    Iam trying to use Flex with Weblogic(8.1.5) portal application. When i use HttpService to make call to the server, it returns the contents from the server, but it invalidates the existing session. Iam not able to access any other portlets.
    When i use remote object call it gives me SSL handshake error.
    How do i resolve this. Pls help me out

    Hi Sharath,

    Application looks great. You have to use some server side script to connect to the database from a Flex application. You have three options to interact with the database. You can create a .ASP page which will listen to your request and do the database operations. You can also expose the .NET functions as web services and access them from the Flex application. If you are looking for a RPC kind of solution, where in you want to invoke the functions in the .NET object from your Flex application, you can try WebORB. Below is the URL to the weborb site. You can even find code samples for all the above options i.e. web service/http service/RPC
    Hope this helps.

    Hi Chandu,

    Your question was on how to map AS objects to Java objects. I have created a post on this, check this post on my blogs: mapping-action-script-objects-to-java-objects

    Your AS class should reside in your Flex application and the mapping to the Java class is done in the AS class.
    Rendering the data in a datagrid is completely a different problem. If you want to populate a datagrid with the ArrayCollection you can use the dataProvider property of the datagrid. In case of the text input or anything else, you have to retrieve the value from the object (returned by Java) and then set it to the appropriate property of the component. Please refer to the language reference of the respective components details.

    Hope this helps.

    I’m playing around flex and blazeds for a while now and still pretty confused at it. I found your tutorials easy to follow but i still have a question.

    I can now send and receive messages through topics and using JMS-adapter. But my problem is the authentication of users, can i authenticate users through topics? can you help/guide me on login/authentication part? i don’t know what approach i will do to make this.

  16. Barry Says:
    March 26, 2008 at 11:56 pm

    It seems that the returned data in this case must be processed synchoronously via a result listener. Try the following to see if it works for you,

    private var ro1:RemoteObject = new RemoteObject(”prctest”);
    ro1.getEmployeeList1.addEventListener(“result”, buildDG);
    ro1.getEmployeeList1();

    private function buildDG(event:ResultEvent):void {
    //build your DG here….
    dg.dataProvider = event.result;
    }

    Note that event.result seems exists only in the event handler, so you won’t be able to assign it to a shared variable and use it in a different function.

    We need some help. We have a Java Applet that captures images on a users desktop. How can we convert the image from a byte array to string to pass to FLEX. Is there a better way to pass the images from the Applet to Flex?

    Any ideas would be greatly appreciated. Also do you have time for any consulting on a project??

    Hi Sujith

    I am able to work with BlazeDS , is it necessary the package structure for AS and Java classes match for mapping them,

    for ex:
    can I have a java object in package say com.abc.data.util

    and the mapped actionscript class in package com.abc.client.flex.util

    I have tried it and its not working, I have tried looking up the documentaion but nowhere it taks about package structure being the same

    Can you please tell me if the above is true.

    Hi Sujith

    I am using BlazeDS to send data to my flex client. However is there API
    or a way to find out how many bytes of data the client received from there server
    if I make a remoteObject call.

    Basically I am trying to find out how many bytes of data is transffred over the wire through BlazeDS……

    Can you please explain the blazeDS serialization and how it works.

    For eg: I am sending a list of HashMaps. Each hashMap is a set of key pair values and corresponds to 1 row of data in DataGrid. The hashMap keys are columnNames
    and the values are the cell values..

    Say for eg If I am sending 3 hashmaps, Since the keys are columnNames, this information is duplicated as keys in all the 3 hashMaps. I know on java side Its using the reference. But once the data is serialized through BlazeDS is that maintained or not

    Any help will be greatly appreciated.

    -> About using different database urls with destinations in the hibernate assembler in LCDS.

    Hi Sujith,

    I have a question that I could not find any information in the web. I thought this might be familiar to you. I am having a flex app which uses data service destinations using hibernate assembler. But since all the destinations (whether runtime or xml for application scope) gets loaded on startup, I am unable to change hibernate configuration especially the database name based on the user logged in.

    For example. Consider a flex app with hibernate in backend.
    Company XYZ should use XYZ database
    Company ABC should use ABC database.

    Note: Both xyz and abc have same tables or data model.

    Also changing the Original hibernate configuration (using programmatic API like Configuration()) has no effect. Also note the data service destinations once created
    on server startup, cannot accept a new hibernatconfiguration as well, even if it would
    it will apply the same changes for both XYZ and ABC users.

    Any help on this would be appreciated. Thanks.

    Hi there,

    I have set up some ‘destinations’ in Blaze-DS, and am successfully using ‘Producers’/'Consumers’ from my flex application to connect to these destinations and exchange messages.

    Now, since my server is hosted, any one in the world, who knows what the destination name is can connect to this blaze-ds destination of mine(from a simple flex app), and send/recieve messages. Isn’t this true? How do i prevent unauthorized access?

    Let say there are 2 different server. JMS client (producer) reside in Server A, and Flex client (consumer) reside in Server B. JMS is going to publish some data into BlazeDS destination and allow the Flex subscribe it. The questions are:
    a) The main question is the BlazeDS destination should reside in which Server??
    b) The BlazeDS destination can reside in Server A?? If yes, how is the Flex client going to subscribe the data in different Server?? Any idea and examples??
    c) Is it a must the BlazeDS destination should reside in Server B? If so, any idea/example that enable the JMS publish the data to different Server?

    Hi Sujit,
    It’s me again. I really need some advise from you.
    Nowadays, “performance” becoming an important issue especially when develop a real-time application.
    I goes for BlazeDS Messaging also because of this.
    I wonder how fast/good is the performance when millions of data push to client side.

    Is it the performance is actually depends on network protocols?
    E.g. BlazeDS offers long polling & streaming. Is it “Streaming” faster than “polling” ??

    Where LCDS (commercial product) offers RTMP & socket-based protocol. So is it “RTMP” will faster than “Streaming” which offered by BlazeDS ??

    As a conclude here, is it LCDS Messaging better than BlazeDS Messaging when want to develop a mission-critical Real-Time application??

    Looking forward to your help. Thank you.

    Please have a look at view states in Flex. There is nothing like a page in Flex, you will have to think in terms of states or keep adding a removing components in a single state.

    I found this post “http://coenraets.org/blog/2007/03/real-time-market-data-using-apollo-and-flex-data-services/” by Christophe which explains that you must specify the actual server address & port in the services-config.xml file rather than leaving the ‘tokens’ in place to use DS with AIR apps.

    He says:

    “instead of:
    http://{server.name}:{server.port}/{context.root}/messagebroker/amfpolling

    use:
    http://localhost:8600/messagebroker/amfpolling ”

    I’m using BlazeDS on port 8400 and found this worked:
    http://localhost:8400/{context.root}/messagebroker/amfpolling

    And similar for Weborb except on port 80.

    changed this:
    “weborb.php”

    to this:
    “http://localhost:80/Weborb/weborb.php”

    Also of worthy note, I had to ‘clean’ my projects in Eclipse after making a change to the service-config.xml file before the change was reflected.

    Now down to securing the channels…

    Hi Kev,

    Yes, you got it right. In case of AIR application you need to give the complete URL :) and yes, you have to clean your project in Flex Builder.

    Check out this URL (might be useful :) ) http://sujitreddyg.wordpress.com/2008/07/03/creating-blazeds-channels-at-runtime/

    Feel free to ping me if you think I can help you :)

    Hi Sujit,

    Thanks for your reply and for this great site :)

    I notice that you sent some information to another person regarding securing AMF channels – could you please forward to me also?

    I have read that the simplest way is to create a local user list to which you allow certain channels access. But I was wondering how hard it would be to query a database on the server for a list of users?

    (runtime channel creation is very useful too – thanks)

    cheers!

    Hi Sujit,

    I am new to Flex and using the Flex Dashboard sample given at http://www.adobe.com/devnet/flex/samples/dashboard/dashboard.html

    I need to use my existing Applet(which does publish/subscribe with backend), to update data in the individual pods.

    Using Javascript am able to call the methods inside the Dashboard main mxml. From there am not knowing how to pass the data to the individual pods.

    Can you please help me on this ASAP.

    Hello all,

    I am new to BlazeDS and am working on a project that requires it. I came across your article and let me to take this opportunity to tell you that you put out a solid work. I am just wondering how can I do the following:

    I have my back-end written in Java, and in my Class I have an array of Strings that keeps updated. In my client side code, I invoke the getter method for this array. I would like to display those messages at the client side as soon the server knows this array got updated.

    I tried to listen and get the array data every XXXX amount of time. Unfortunately, this approach did not work. I got all the results at the very end (all at once).

    Please let me know of your ideas, and if you have sample code that would be very helpful.

    Thank you,

    I see that you have comments about modularization in Flex and articles about using RSL in Flex, so I have a request. Point me to the ‘best practices’ for using those techniques with AIR. I have an AIR ‘container’ that has lots of Flex components that are modular AND rely on the Player to cache both the Flex framework and my own libraries. How — precisely — do you make those enhancements with AIR.

    No, I don’t want to be told that desktop applications don’t need to be small and compact — nonsense — no one wants to download a 5MB update if only a .5MB update is needed. How do we do this with AIR? Your thoughts would be much appreciated since you cannot find anyone in Adobe product management willing to talk about the apparent disconnect.

    I am a designer turned developer who is moving from Flash to Flex and I have been asked to help someone plug their site into the photoshelter api (the basic documentation for this is at:http://pa.photoshelter.com/help/index/tech/bsapi). I have some limited experience in using Amfphp to make mysql queries through Flex, but am unsure whether, or how, I can access this kind of api – and can’t find any info. that clarifies things for me. Do I need to use a solution like Blaze DS and Java, or can I manage the session calls through amfphp? Can you give me any pointers on this? Thanks.

    Hey Sujit,
    This is Vishnu. Good to know you are from BITS PIlani,I’m from BITS Pilani too, passed out in 2007.

    So lately I’ve been trying to learn FLEX by myself. Was trying to build a twitter mashup using Chris Korhonen’s Creating Mashups with Adobe Flex and AIR. I’m not using the Flex Builder. I compiled my mxml file and transferred the generated swf file to the root of my HTTP server. I also included a crossdomain.xml file in the root since the RSS feeds it was trying to access doesn’t reside on my server.

    Despite this i keep getting an error:
    [Security error accessing url" faultCode="Channel.Security.Error" faultDetail="Destination: DefaultHTTP"]

    Here is the code:

    twitter.mxml

    Tweet.mxml

    cross-domain.xml

    Where am i going wrong here?

  70. Sujit Reddy G Says:
    November 25, 2008 at 3:14 pm

    Hi Vishnu,

    Looks like the code got truncated.

    You will need the crossdomain.xml on the server from which you are accessing the data from and not on the server where the SWF file is hosted.

    Hope this helps.

    Hi Jai,

    I don’t think you need to worry about AMFPHP for accessing the API you mentioned. Looks like they are sending their response as XML. All you need to do is to use HTTPService component and access the XML.

    Please find more details on how to use HTTPService at the URL below.

    Hope this helps.

  73. Jai Says:
    November 28, 2008 at 9:33 pm

    Thanks Sujit, that is a useful confirmation. However I remained rather confused about security. I have to access the photoshelter api via SSL. From what I gather, that seems to mean that I must use a proxy of some sort… Is that true? If I authenticate by sending username and password over HTTPService, don’t I make my archive at photoshelter very vulnerable?
    Would it still be worth it to be running the httpService through BlazeDS? Would it make any differences to speed? Again, thank you so much for your helpful advice.

  74. Jai Says:
    December 2, 2008 at 2:02 am

    After further research, I now believe that I have to set “useProxy” to true and then configure my https service via BlazeDS – or a php proxy – in order to be able to communicate via https – and send necessary username and password authentication. (There seems to be very little clear documentation on using HTTPS with BlazeDS on the web…) So although I don’t need to use secure-amf, will it perhaps give me increased speed? Even though serialising from xml, and back into xml at the other end…

    Hi sujit,
    I have gone through the article “Sending messages from Java to BlazeDS destinations using MessageBroker”. I have implemented it and it is functioning well. Only the exception is that I am making use of LCDS instead of BlazeDS. Any way, your article provided a great help indeed.

    Now all I need to send message to few(not arbitrary)consumers. Suppose there are 10 consumers and I need to send message to 7 of them. How could it be decided from server side? Could it be made possible by modifying the code of MessageSender.java? Actually I need to decided it from server side prior to send push data. Please help.

  78. Sujit Reddy G Says:
    December 4, 2008 at 2:47 pm

    Hi Jai,

    You can go ahead and use HTTPService without BlazeDS. I don’t think it will be vulnerable to pass credentials using HTTPService over HTTPS.

    You will need BlazeDS if you cannot communicate with the service provider directly. That is the service provider is not having a crossdomain.xml on his server.

    AMF will definitely increase performance.

    URLs below might be useful. In the BlazeDS dev guide, try to read about channels and RPC services, especially proxy service.

    hey Sujit,

    I have a ‘design’ question for you…

    I’m building an inventory application using Flex, AMFPHP, MYSQL and the Cairngorm pattern. Take 3 tables as an example: Categories, Colours, Products.

    Categories:
    CategoryID 1
    CategoryName Pants

    Colours:
    ColourID 1
    ColourName Red

    Products:
    ProductID 1
    CategoryID 1
    ColourID 1
    ProductName Cargo Pants
    Price 20.00

    Now when I init the app, I send 3 events to gather all records from each table and populate 3 ArrayCollections in the ModelLocator. Great, this works fine.

    But I want to populate a Datagrid which contains the fields “CategoryName”, “ColourName”, “ProductName”, “Price”.

    I can think of 3 ways to do this:

    1) create a new ArrayCollection in my ModelLocator and populate this by calling a PHP service which does a joined SELECT statement – disadvantages, need to refresh this AC whenever I change the contents of any of the others, duplication of data being sent/received from the server, ?

    2) create a new ArrayCollection in my ModelLocator and populate by iterating through the 3 ACs in Actionscript each time any of them change – advantage, no excess data sent/received from server but potentially higher processor usage?

    3) don’t create a new ArrayCollection, but use ItemRenderers for each DatagridColumn which takes the appropriate ID field and returns the Name field – again, no excess network but potential high cpu everytime the DataGrid is refreshed

    Or is there another way that I cannot see!

    Maybe this is a simple design concept that people learn in Software Design 101 – but having missed that class, I’m playing catchup!

    Cheers!

  86. Sujit Reddy G Says:
    December 11, 2008 at 2:45 pm

    Hi Kalyan,

    It all depends on the channel you are using. The capacity planning guide which I pointed to you previously has comparison for all channels. BlazeDS supports only Servlet based channels like AMFChannel, HTTPChannel, HTTPStreamingChannel and AMFStreamingChannel. Where as LCDS has these Servlet based channels as well as Java NIO based channels (which scale a lot) and RTMP channel. The code for both LCDS and BlazeDS is same for the channels supported in both the products.

    In the capacity planning guide, you can look at a section where they are comparing Servlet based channel with NIO based channels. Basically, Servlet based channels can handle only few hundreds of clients at one go as there are restrictions on number of threads a web server will run and each connection to a client will occupy one thread in the case of Servlet based channels.

    Hope this helps.

    Here it actually converts the java object to flex as object with no problems.

    But when i am passing the as object to java, it somehow nullifies the array (myAvrgDays) in the java object.

    Hi Ragini,

    I think FlexContext.getHttpRequest() is null in a JSP page because the MessageBrokerServlet is the one which sets the HTTPRequest object to the FlexContext
    As the request is not going thru MessageBrokerServlet I don’t think you will have the HTTPRequest object. Please try the normal J2EE way to get access to the cookie in your JSP page.

    Hope this helps.

    hi sujit,

    i am working on a project using weborb for .net and flex 3.
    i am retrieving an Array of strings from asp.net using weborb. the array has the right length; but all the values are blank. in weborb i have used the test-run feature to invoke this same call; and the array is returned with all the values. i have done the same from an aspx page. maybe it’s the way i am reading the array into actionscript? please help me (and other weborb for.net+flex users) with a tutorial on interaction between these two(and a solution for my problem too :) ) thank you in advance. daniel
    ps: if it makes a difference; the class is written in c#; and the class retrieves a static array and returns an array.(returned_array = static_array).

    Please let me ask you a question.In our application, we are using a custom messaging adapter which uses a rtmp channel. Our intension is to get an acknowledgement in the server. In our case, let us assume a java class is the message producer(like MessageSender.java in your article “Sending messages from Java to BlazeDS destinations using MessageBroker”). If we would have sent message using Flex Producer component, we can optionally specify “acknowledge” and “fault” event handlers for a Producer component. How exactly this could be implemented when a java class is sending the message and this class is acting as a message Producer.

    Hi Sujit,

    I am working on blazeds applications where i
    want to detect browser close event of on server side.
    I have tried using adaptors and session listeners,
    but nothing going right for me.

    i saw your blog and thought that you are the right person to
    solve the problem.

    So please let me know if there is any solution for
    the same.

    Hi Sujith,

    We are trying to integrate Flex with a Single-sign on product (Siteminder). In our environment, the incoming request to the Flex application will get routed via Siteminder. Siteminder will authenticate the incoming request, then append few authorization details (user profile, like role, department, etc) in the Http header and redirect the request to the Flex application.

    Our requirement is to read the http header information, and take some business validation based on user profile. But we couldn’t able to find any direct functions, which helps us to read the http header information. When we browsed through Flex documentation, we found couple of functions for it (like URLLoader). But these functions require sending explict request to the server and reading the response header. But in our case, we are not sending any explicit request to Siteminder. Rather we are just trying to read the http header, when the user request hits the swf file.

    We have managed found a solution using JSP wrapper and Flashvar. But we don’t want to use a JSP wrapper in-between. Is there any other alternate way to read http header? Any suggestion would be greatly appreciated.

    Thanks,
    Kumar

    Hi Pravin,

    Flex application running in Flash Player in browser will not dispatch any event when the browser is closing. You will have to use ExternalInterface for this. Pleaes find more details on how to achieve this at the URL below.

    Hi Souvik,

    Do you want an acknowledgment on the server ? So, you want to make sure the message is being delivered. Did i understand it correctly ?

  109. Sujit Reddy G Says:
    January 6, 2009 at 2:00 pm

    Hi Kumar,

    I don’t think you can do this with out a JSP wrapper :) You basically need a JSP/container/server which will accept a POST/GET from the SSO server. If you are worried about passing these values as Flash Vars, you can consider adding the values in a persistent storage on the server and generate an ID for the same. Now pass this ID to your Flex application and get the values SECURELY from Flex application using the ID from the persistent storage. :)

    Hope this helps.

    Hi,
    i am a coldfusion developer and a flex aspirant. i want to know how we can integrate flex with blazeds and coldfusion. i dont know much abt blazeds. Can we make a chat applicatin in coldfusion with blazeds support and integrate in a flex site? I have tried ur example with blazeds and java and was quite helpful. but the problem is how we can use blazeds along with coldfusion. is there anything we need to change in the CF admin for the blazeds to work along with CF.Is that possible? any tutorial links would be helpful..thnx..

    Hi Sujith,

    Nice articles. In your post “Session data management in Flex Remoting” you talk about calling static method FlexContext.getFlexSession() for Flex Remoting. But, I’m using Servlets. Normally you set objects in HTTP session. But Flex also has one session, and due to some reason 2 sessions are getting created. So I want to access the flex session instead of creating http session in servlet. I tried FlexContext.getFlexSession() but it doesn’t work. It returns null. Can you tell me how to achieve this?

    Thanks,
    Romil Sinha

    Hi Sujit,

    I got your reference from Sambhav Gore in Bangalore.
    I have a few queries related to session management in BlazeDS.
    1. Once a session has been established, how do we ensure that the next request coming in is from a valid user.
    2. How does cache management work in Flex. Is it possible to maintain data at the client side for the specified amount of time?

    Thanks,
    Rabiya

  114. Sujit Reddy G Says:
    January 20, 2009 at 12:43 pm

    Hi Rabiya,

    1. What exactly do you mean by valid user ? if you meant the same user, then you can just check for some object stored in the session. Requests from same user will return one session object
    2. Flex is state full client, any instance of the objects created will remain as long as the user doesn’t reload the entire SWF. That is by refreshing the page loaded. If you want to store a object only for a specified amount of time, you can use a Timer and then remove the instance end of the period.

    Hope this helps.

  115. Sujit Reddy G Says:
    January 20, 2009 at 1:08 pm

    Hi Romil,

    In a Servlet you can get the FlexSession object. It is stored in HttpSession as an attribute. Please get attribute named “__flexSession” from the HttpSession. FlexContext.getSession() works when the request is received my the MessagebrokerServlet only.

    Hope that helps.

    Hi Sujit,

    Is it possible to deploy a flex application using remoting and lcds to a different server? ie remove the flex app from the java web app and deploy it on another server – like a web server?

    The reason I ask is that when running the sample apps on a fresh lcds 2.6 install using flex builder, there is no option to change the output directory. And when we run the samples the desitination cannot be found. So I assume that the flex app must be contained within the lcds web app?

    Is there any way around this? And is this the same situation with AIR apps (that they must be deployed to the lcds web app?

    Hi Sujit,

    I have a real urgent question:

    I want a LineChart to be drawn.
    I have these Timestamps [84, 1000, 34000, 34699, 439999] who are representing the x-Value of DataPoints along the X-Axis.

    Unfortunately the distance between 2 nexted datapoints along the x-Axis is always the same, that means that between the points with x-values 84 and 1000 is the same distance along the axis as between the points with x-values 34699 and 439999.
    But the distance between points with x-values of 34699 and 439999 should be much greater than between 84 and 1000.

    How can I customize the distance between data Points on a LineChart to solve my Problem?

    I really dont know right now and I did not find a solution yet.
    Would be very nice to get some hints.

    Greeting,

    The program runs fine within the Flex Builder environment. However, it does not run from the bin-release compiled version. It doesn’t seem to be talking to the Tomcat server.

    I am trying to write to a file name which is absolute: ie, c:\\….

The client interface has been built with Adobe Flex 3 Builder. The java script has two functions: one that writes a line to a file and another that reads a file. The file name is specified in the Flex client.

    Hope this helps.

    I am looking at adding BlazeDS to an existing Tomcat/JSP application for which we have a functioning web services Flex/AIR app. The app handles lots of images and I felt that AMF would be a good way to improve comms performance.

    However, I am a bit confused. How can I take all my existing JSP based API’s and port them to Blaze so I can use AMF. Today we use Cairngorm as the MVC and HTTP services to do the requisite get and post actions.

    I just need a little pointer in the right direction.

    http://debuggable.com/posts/setting-up-xdebug-on-mac-os-x-or-win32-linux:480f4dd6-0240-4a90-8fa1-4e41cbdd56cb

    I had to compile the xdebug.so plugin from the v2.04 source for it to install properly under MAMP – luckily someone posted this info in the comments below the post.

    Installed PDTv2 via Eclipse software updates:
    http://wiki.eclipse.org/PDT/Installation

    But then I could not get Firefox to connect to Eclipse – the issue seems to have been some faulty prefs in Eclipse. I just created a new workspace, created a new PHP project pointing to my Zend services directory and imported my Flex project.

    It’s probably sad how excited I am to have this working. No more looking at PHP error logs (well less anyway).

    cheers

    Hi Sujit,

    I am a Flash developer for al long time now and I am trying Flex since 1.5 whenever I get time, I had developed a sample application in Flex2 with coldfusion as middle layer and the MSAccess db, it worked out to b well but went on getting complex as the size increased and I got stucked.

    I have gone through and somewhat understood the BlazeDS structure and worked around the examples too, since I cannot install FlexBuilder I am again stucked in compiling Flex3 files on command line comipler which will be deployed on preconfigured tomcat which comes with the BlazeDS Trunkey download whic is for free.

    The same thing is with Carngorm architecture I have gone throught the documentation and some what understood but could not implement due to the lack of any sample application which is with the CG framework and the actual sample application sourcecode, which will make it easy for me to understand the structure in details and help me develop the application on CG framework without any fear.

    I am seeking your help on following points:

    1. Any small sample cairngorm implemented application along with cairngorm framework used in it and the application source code, to understand the CG framework in actual use.

    2. What are the steps to compile the flex application on command line for BlazeDS, so that it takes the configuration from the service-config.xml or other service related xml rather than the default flex-congif.xml. [in short how to compile the flex application on command line using Flex SDK 3 not FlexBuilder to make it work on BlazeDS]

    It would be a great if you would help in these points.

    Thanks & Regards,

    Iresh SA

    Sujith,

    I am having Jboss as my application Server and using Flex for my front end . Essentially I am to convert one legacy application into a Flex one . I am running into the problem
    a lot . In the Java Code of the application lot of application specific Parameters are stored in Request Object and Session Object .is there a way by which I can access HttpSession , HttpRequest object in Flex .
    In java if i do session.setAttribute(“userName”,xxx);
    request.setAttrinute(“userName”,xxx)
    how will i do session.getAttribute in my mxml .

    Hi Sujit,
    First of all I have found your blog extremely helpful as I’m just starting off flex. As a part of my project, I am required to upload an image from the client to the server and I’m using a servlet to handle this request. You might have guessed I’m using Java at the business tier. I found a tutorial http://blog.flexexamples.com/2007/09/21/uploading-files-in-flex-using-the-filereference-class/ using the FileReference object and it seemed to be very clear. The JSP code present in the comment section of that blog doesn’t seem to work whenI try to use a similar code in the doGet() method of my servlet.

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    try{
    DiskFileItemFactory factory = new DiskFileItemFactory();
    ServletFileUpload upload = new ServletFileUpload(factory);
    List list = upload.parseRequest(request);
    for(FileItem items: list){
    File uploadedFile = new File(“H:/”+items.getName());
    items.write(uploadedFile);
    }
    }catch(Exception e){
    e.printStackTrace();
    return;
    }

    }

    This is just a test program but it doesn’t seem to be working. When i submit the file for uploading on the flex front end, it continuously says ‘waiting for localhost’ (I have verified the URL of the servlet and the one mentioned in the URLRequest). When I directly try running my servlet on the server, I get a classNotFoundException for FileItemFactory even though I have imported it.

    Do you know why this is happening or If i can do this in an easier way without using BlazeDS?

    Your suggestions would be valuable.

    regards,

    Nikhil

    Hi Iresh,

    For configuring your services-config.xml to your Flex project you just have to add -services “\services-config.xml” to your compiler arguments

    Please find developer documentation for Cairngorm at this URL http://opensource.adobe.com/wiki/display/cairngorm/Developer+Documentation
    You will find sample at this URL http://www.adobe.com/devnet/flex/articles/introducing_cairngorm.html

    Hope this helps.

    Hi Raj,

    Instead of setting the objects in the session or the request, you can send those objects to Flex application from your Java classes. Please find details on how to invoke Java methods from Flex application at the URL below.

    April 9, 2009 at 5:09 am

    Thanks Sujith. Well I did anyalyze this option , but Since i am a newbie I always thought there must be a straight forward way to store session .
    The problem is I have a jsp page which calls a Controller
    login method on failure it redirects to a page and sucess it redirects to different page . It is not structs completely but still works on the similar concept of Structs .I use Java Page Flow.

    I had written the first login.jsp —-> login.mxml
    login.xmlml Parts of Code where I have issues.

    {userName.text}
    {password.text}

    private function validateForm(evt:MouseEvent):void {
    if(validated)
    –call registrationRequest.send();

    I have two functions handleResult and handleFault. This is where my main question is .

    This is my Controller method Login.do
    method login(
    @Jpf.Action(forwards = { @Jpf.Forward(name = “success”, path = “MainV2.jsp”), @Jpf.Forward(name=”retry”, path = “welcome.jsp”) })
    public Forward login(Controller.loginForm form) {
    Forward forward;
    call db validtor
    if(validated)
    return forward(sucess)
    else
    session.setAttrinute(“errorMessage”, “error message from db”);
    return forward(failure)
    }

    Now I dont know what is the problem , no matter what if there is no exception also , i get debug messages in the handle fault method of MXML . I dont hit the handle result case .

    I am not sure why ? How would i handle this if sucess redirect to different mxml , error show message from db .

    I would apprectiate if you point me to some example .

    2. Second question . I have two list boxes in my MXML . I want to add , add all , remove , remove all the values from the two list boxes . Is there any example for that too .

    Thanks

    org.w3c.dom.Document objects from Java are converted to XML class type by default. You can also send String from Java and convert that to XML using XML(yourXmlString)

    Hi Sujit Reddy, sorry but I don’t speak english. I have a question…
    it’s posible retrieve data from a database on MySQL to application in Flex with LCDS and Data Management Services, but without having a flex client that notify all other clients… ie, that LCDS verify the changes in the database it automatically, by example if you enter data in the database from the console of mysql, that Flex LCDS detect changes and update the view in client Flex with Data Management Service, not AMFPolling.

    hi Sujit,

    i am trying to create Flex portlets in RAD and configure it in WebSphere Portal Server 6.0.

    1) know how to create jsp portlet in Portal Server, to create Flex portlet is there a need of FlexPlugin in RAD as per these below PDF
    http://help.adobe.com/en_US/livecycle/8.2/portal_update_lcds261.pdf
    uses FlexTagLib in jsp.

    2) how to configure Flex Portlet in Portal Server with BlazeDS to invoke Java method using Remote Object…..this is much different than BlazeDS with tomcat.

    may be if BlazeDS is configured properly in PortalServer than Flex can invoke Java method same as in tomcat.

    please reply soon.

    Hi Sujit,

    1) I had made portal project in RAD, by using simple “Hello” Flex application (i.e. used generated swf file ) able to view flex application properly in portal server.
    2) if i will use RemoteObject tag in Flex application, made MessageBrokerServlet entry in web.xml for rmi connection. In same project created java class and made corresponding entry in remote-config.xml.

    My Question
    1)By refering to swf file in jsp through WebSphere Portal Server it is possible to invoke JavaObject using RMI?, if both are deployed on same war file.
    2)while creating Flex project where should i point to i.e. Root folder, Root Url, Context Root. because i am using WebSphere Portal Server.

    In “creating Blaze channel at runtime”, i think it talk about without making entries in remoting-config.xml should be configured in Flex application.

    thanks in advance.

    Hi Sujit, this is a very useful website. Question:

    We are trying to slowly integrate Flex 3 into an existing web app. We plan on adding the Flex client into iFrames where appropriate. The problem that I’m addressing is how to integrate a mixed J2EE/Flex client into a single web app on the server. For the Blaze side we want to hit java classes via destinations.

    The web.xml file contains a which forwards to a .jsp login form (we’re using FORM auth-method). When the BlazeDS url-mapping is added to security-constraints any RemoteObject calls will hit this login-config servlet. That’s OK. We know it’s requesting the Blaze servlet and can try to respond accordingly (i.e. not returning the HTML logon form).

    I tried returning an AMF3 object back to the client (a string that said “noAuth”) but the Flex client had no clue and spewed a “BadVersion” error. I was hoping to have the client recognize some kinda specific String/error so that it could prompt the client to logon (say, in the event of a session timeout while in the Flex portion of our app). I also prefer to avoid creating my authentication via Blaze as both my J2EE client and Flex app are sharing the same session and thus the same timeouts and other settings.

    This seems like a good strategy but I just can’t figure-out how to make it apply. If this isn’t a good strategy do you have any suggestions given this issue? Certainly we can’t be the only Java shop trying to slowly migrate Flex into our web applications. Thanks.

    -Doug

    Hi Sujith,

    My task is as follows ,

    a) I have an AdvancedDataGrid , I have to render icons and label coming from the server . icon data from server comes as byte array. So I created a an image render which has an HBox and to the HBox I added an Image class and a Label Object. I am able to see icon and text as expected,
    now when the user clicks on the cell, I wanted a ComboBox to drop down with choices which again should show the icon and text.

    b) so I created a new class extending ComboBox and I created another image renderer , which is the ItemRenderer for the ComboBox. The dataProvider is an Array of Strings, In the image render based on the “data” property I set the Image and Label in t he renderer

    c) now I set the itemEditor as the above custom ComboBox

    All the above works fine to a certain extent. However when ever I click the Cell the cell changes to a DropDown List and starts showing the “string” from the Array which was the data provider for the ComboBox. and when I click cell again the DropDown List opens and I see the Icons and Text, I want to avoid showing the “text” part when I just click the cell

    Hope I was able to explain clearly.. if you have an exmaple or a refernce to some material on how I can achieve this I will be gratefull

    Regards
    -Chandu

    Hello,

    We are trying to build a high definition PDF (300 dpi, for book printing) from pages designed in a FLEX tool ( like scrapblog.com)

    The flash is included in a web site written in Java/J2EE, so the PDF generation will take place on the Java server (based on a description of the pages sent by the flex tool with BlazeDS

    We need 300 dpi definition and the ability to build the PDF without any template (since the user will be able to change the layout of the pages he wants to print : the description sent by the flash tool includes the location, orientation and source of all the elements in each page).

    From what we have seen up to now, the lack of a template can be difficult to handle with java libraries.

    Any idea how such a PDF can be built in Java ? Or lacking that, with other languages (such as PHP) which could be added on the server side.

    Thanks for your help.

    Hi Sujit,

    I want to appreciate the time you put into replying to the blogs queries. It is tremendous..
    I am using LCDS. In API docs, ServerConfig class xml property should hold all the detinations which are present in the services-config.xml file.

    In my services-config.xml file. i am doing something like below

    but when i access the Services.xml property on creationcomplete. i notice that some of my destinations are missing from the file remoting-config.xml. Due to which i am getting the error from the method

    private static function getDestinationConfig(destinationId:String):XML

    Can you please show me some pointers..

    Hey Sujit,

    First of all, thanks in advance for any help you could bring to me. I really appreciate your time on this.
    Now, I’m working with Charts, right now I’m facing the problem, of the label on the chart. By request of my client, he is asking me to solve the issue that comes up when the label it’s too big, and the graphic (BarSerie) too short, so then the label appears as “…” ok, yes we do have the tooltip, but those graphics are also exported as PDF files, and the requiere to have the graphic information on the report, so I thought that might be a way to specify dinamically to the BarSerie the labelLocation property.
    My problem is that I’m not really a Flex programmer, I had been focused on Java but the client asked me to create this project as this interaction Flex + Java + Oracle. So…

    Do you thinks is there a way to create that dynamic position?

    Also, on the same project and as a plus of the strategy… And taking the advantage of your knowledge, I’m exporting to PDF and Excel, but right now I’m using a JSP page to call the interaction to the exportation. So the way I’m exporting to PDF is using AlivePDF, no problem there, because that API allows me to add images, so there I add the chart object. The problem comes up, when I’m trying to export an image to the Excel file.
    I just started to read about as3xls project on googlecode. But if you have some sample that I can use, would be wonderful!

    Once again, thanks and thanks and thanks in advance.
    I’ll be waiting on your answers!!
    Have a gr8 day!

    2. Have a timer and send request to the server to get data the modified data
    3. Use one of the polling channels in BlazeDS Messaging service and get the modified data

    I am using the Google Calendar API created by you. I am facing two problems while using that:
    1. Firstly if I try to delete an event I get this error:

    ArgumentError: Error #2008: Parameter method must be one of the accepted values.

    Debugging the error gave me some idea that it was coming at:
    urlRequest.method = “DELETE”;
    Any idea on how to rectify it?

    2. Second error is when I try to get events between a given date range. The problem is that the date gets converted to UTC format in ur API and if I try to get events for a single day, i get in result for 2 days.

    Would appreciate if you could help me out..

    Hi Sujit,

    I want to integrate Flex and BlazeDS with my Struts framework using remote object.
    I am able to get the parameters from Flex client to my remote method as arguments.
    But I was earlier using forms to get these parameters and used that form object at many places to update my application.How can these be achieved in Flex ?
    It would be of great help if you could reply with a sample application integrating Struts with Flex and BlazeDS.

    Thanks in advance,
    Lalit.

    Hi Sujit,

    As per my understanding ,Flex is not supporting Map DataType(HashMap/Map). So i wrote the below class to use Map in my application.

    The problem i am facing with doing this is, I am not able to bind my map with the ‘currentState’ property of a “Canvas”. The Class which i have written extends the ArrayCollection but still i am facing issues with binding.

    My Map class which extends ArrayCollection:

    package com.util
    {
    import mx.collections.ArrayCollection;

    public class Map extends ArrayCollection
    {
    private var keyNames:Object = new Object();
    public function Map()
    {
    super();
    }
    public function put(key:String,value:Object):void
    {
    if(keyNames.hasOwnProperty(key))
    {
    setItemAt(value,keyNames[key]);
    }
    else
    {
    keyNames[key] = this.length;
    addItem(value);
    }
    }
    public function getValue(key:String):Object
    {
    return getItemAt(keyNames[key]);
    }
    }
    }

    My MXML:

    It would be of great help to me, if you could post a solution.

    You can try Messaging service BlazeDS/LCDS or try one of the below

    Hope this helps.

  273. Sujit Reddy G Says:
    August 28, 2009 at 6:29 pm

    Hi ishai,

    This might because either the destination doesn’t have any channel defined or Flex application is not recompiled after configuring the channel. You can check the channel used by the RemoteObject by just putting a break point and watching the RemoteObject instance variable.

    Hope this helps.

    Hi Tobias,

    You should be changing the endpoint URLs in your services-config.xml file to point to your hosted website and the Flex application has to be recompiled with the updated services-config.xml configuration file. That change should be sufficient to deploy.

    1. I have used Flex Remoteobject to call Coldfusion CFC to Read/Update/Delete process on MS SQL Server DB for our application. I was not using LCDS. But now i am using LCDS and its charts says that LCDS has RemoteObject. What is the difference between the first RemoteObject and LCDS RemoteObject ?

    2. Is Messaging Service in LCDS and BlazeDs is Same ? Is BlazeDs is a subSet of LCDS ?

    3. I am trying a simple chat application with Producer/Consumer approach. But it is throwing error.

But one thing I would like to know is about Search Engine Optimization (SEO) of Flex sites. Coz when I view the site source, it shows just an swf embedded and I think it don’t help from the SEO perspective. So can we do SEO with flex??

    Hi,

    I’m playing around with the zend framework (zf) and flash builder 4 (fb4), and I’m a bit lost, i read about the new features in the fb4 for connecting with data, so i configure a new zf project, with a virtual host (www.zf-fb4.test).
    I followed the structure recommended on the zf site having the library 1 level behind the public_html folder, create some controlers, default, admin, and service, the default launch the flex app, the admin is serving HTML and javascript, and the services is my messageBroker, where i start the Zend_Amf_Server.

    The problems came when i try setup the data services in fb4. i cant get to the services controller.

    In the URL i specify http://www.zf-fb4.test/services/amf
    where services is the name of the controller and amf is the Action where i start the Zend_amf_server, and use the addDirectory() function to specify the “services” folder under /application/services.
    but i cant get it to load the services in fb4.

    In the file field on fb4 data services wizard i select the index.php on public_html sence it reroutes the requests to the services controler, and amf action.

    But it doesn’t work, my objective is to use the all zf as a server platform, and flash(flex) on the client side for the front-end, and zf and xhtml+ajax on the backend.

    how can i do this? Can you give me some lights?

    Thanks

    Hi sujit,

    Thank you very much for your reply for my earlier post.I’m using flex 3, java, blazeds and spring framework for web application development.

    I’m handling session expire event in java side and flex side in following way.

    I’m setting a sessionId session attribute in flex session once user login to the system. It is done in a java class following way.

    FlexSession session= FlexContext.getFlexSession();
    session.setAttribute(“sessionId”, session.getId());

    Then in each remote call I’m checking the session id as in following code.
    if((session.getAttribute(“sessionId”)==null) || session.getAttribute(“sessionId”)!=session.getId()){
    throw new Exception(“no session”);
    }

    If session attribute is null or stored session id is not equal to current session, exception is thrown.

    I’m catching this exception at flex client side within the fault result handler of remote object call and displaying the login page.

    public function userListFaultHandler(event:FaultEvent):void{
    if(event.fault.faultString==”no session”){
    //shows the login page
    Application.application.showLoginView();
    }
    }

    Can you see any issues or cons in this approach?

    Thanks

    Hi

    I am using the blazeds server. I have created the destination and i am able to recieve the messages.

    The issue i am facing is that i have my java program which keep sending the messages to the blazeds server. At this point i have no client(browser) to consume the messages.So all the messages are accumulated at blazeds. At one point there are so many messages that my weblogic server goes out of memmory. So my question is how to destroy those messages which are not consume. I am using the tag but this does not seem to work. Please see the configuration below.

    Snippet of Java program:
    AsyncMessage msg = new AsyncMessage();
    msg.setDestination(destinationNameFlex);
    try
    {
    msg.setMessageId(objectMessage.getJMSMessageID());
    }
    catch(JMSException e)
    {
    }
    msg.setBody(data);

    MessageBroker.getMessageBroker(null).routeMessageToService(msg, null);

    Thank you so much for your excellent work and support. I recently decided to take out WebORB and replace it with BlazeDS and BlazeMonster-generated code. I’m under the gun for a demo to sell Flex to my management.

    I noticed that with BlazeDS/Monster-generated code, all collections are ArrayCollections, rather than Arrays by default with WebORB. I have a complex (deeply nested and circular) object model and I need to fetch large record sets to the client. When I switched to the Blaze solution, I noticed a considerable slow down in performance.

    My questions is, can I make Blaze send only Arrays (and make the corresponding changes in the generated VO’s), and then just convert to ArrayCollections on the client when/if needed. I suspect this will recover the performance hit I took by switching. I can easily fix up the generated VO code, but how do I force BlazeDS to send only generic arrays? Is there a setting somewhere?

    Thanks again for your generous support to the Flex community.

    hi Sujit,

    I have to traverse an xml tree and build an object(for instance Map) that shows the parent and the children as a collection( parent id – collection). My xml is similar to this.

    I should have properties of the node as object properties. What is the best way to do this?

    Thanks.

    Hi Sujit,

    I want to pass custom properties like host and port to a java class specified in remoting-config.xml.
    I tried something like this,

    com.selectica.javaapi.CxJavaAPI
    localhost
    7000

    but i am getting an error like

    **** MessageBrokerServlet failed to initialize due to runtime exception: Exception: flex.messaging.config.ConfigurationException: Unrecognized tag found in . Please consult the documentation to determine if the tag is invalid or belongs inside of a different tag:
    ‘/remote-host’ in destination with id: ‘CxJavaAPI’ from file: remoting-config.xml
    ‘/remote-port’ in destination with id: ‘CxJavaAPI’ from file: remoting-config.xml

    Now in this case actually my class CxJavaAPI has a constructor which needs the host and port .Is it possible to achieve this? If yes please let me know.

    Thanks in advance,

    Hi Sujit,
    I am having a flex application with BlazeDS and Remote Objects are used to perform the business logic. The remote object also creates a RMI client object and communicates with the RMI server which inturn performs some DB operations.

    After approximately 30 seconds the AMF channel disconnects with a Fault while the backend is still working. The AMF is simple AMF.
    I have tried setting the requestTimeout=0 and also -1 on the remote objects, but the result is same.
    Any help is much appreciated.
    Thanks in advance.

    Morning Sujit,

    I have a problem with the new FB4. I would like to use the generated php wizard but cannot filter the datagrid using filter functions?

    Basically I was working on an date range filter that can filter the data in the datagrid connected to the mysql DB. I can only get it to work if I hard code the whole project and use arraycollections in the main application.

    Please could you create an example that uses dates and applies a range filter in flash builder 4…it would be a massive help?

    Thank you

    Hi Sujit, I have a question related to Flex 3 and ColdFusion that it might be simple to answer but I have been struggling with it for a while.
    I need to create a Flex application to use with ColdFusion and although this is a simple procedure when we are creating the project in a computer where you have ColdFusion installed locally (as all books shows examples of it), but what if the ColdFusion server is installed in another machine in the network?

    My current situation is the following:
    - I have Flex Builder 3 install in my PC at work and its workspace is in a folder in the network outside of my PC.
    - We have a server (ISWEB1) partition in two drives; C, where the ColdFusion 8 is installed and D where all the files the developers work with reside. The ColdFusion installation runs in a server where IIS is used as the web server.
    - I have the drive D on the server ISWEB1 mapped to one of my letter drives and can access it easily
    - The drive C on the Server can only be accessed remotely (or through the web to access the ColdFusion admin page) and is not exposed to the network as drive D is.

    My problem is, I need to create a Flex 3 application that uses ColdFusion using remote object access service (CF Flash Remoting) but I wanted to point to the installation version on the server ISWEB1 and not to the one installed locally. The Configure ColdFusion Server screen in the Flex Builder asked me for the location of ColdFusion root folder, Web root, and root URL. There is no way I can point to the server (ISWEB1)where ColdFusion is installed as those fields seem to required a address that points to a local install or a mapping on that local server.

    So how can I go about to create a project in Flex that uses ColdFusion that is not installed locally? The work around that could be used is to use the ColdFusion developers edition I have installed locally and use during the creation of the project in Flex Builder, but then I would have to have all the same data sources, mappings, and CFCs in my the local server in order to test, which seems double work. To aggravate that when you try to test the application Flex writes the files to the local server and unless you have everything available locally it would not work properly. I am trying to avoid duplicating the work.

    I am seeking some input about session authorization. I am assigned with the task of authenticating against a mysql data table. A userName,userPassword challenge. The development tools are Flex 4, LCDS 3 B2. Is the fiber model able to handle these request, and if so can you recommend a place to start researching or would the Spring framework be better suited for this type of task?

    Generally 10-15 users uses the system simultaneously. The server side code sends
    approx 3000 messages in one second on the destination. Everthing works fine but
    some time the client misses few messages. It happens sometimes. It is difficult

    I have developed the dashboard in my application using flex 3.0. For this I have used JSP wrapper around the flex application. My application runs on JBoss application server. for communication between flex app and my application I am using LCDS. HTTPService component is being used to receive data from the server. Channel definitions are given in service-config.xml for amf and http channels and for both secure secure and not secure mode. In my proxy-config.xml I have defined Channels and destinations.

    In my development environment both secure and non secure mode were working fine. Now when I have deployed it behind the hardware load balancer(which accepts secure requests only and if the request is not secure it redirects it to secure url) there is no response from the message broker servlet. One thing more I have observed is when the environment is non load balanced there are request like ‘http://{server.name}:{server.port}/{context.root}/messagebroker/http’. and these requests are post request. But in load balanced environment with ssl the request is again like ‘http://{server.name}:{server.port}/{context.root}/messagebroker/http’ which is a post request and it is redirected to ‘https://{server.name}:{server.port}/{context.root}/messagebroker/http’ which is a get request. The content returned by this get request is null.
