    Can you give your opinions on concurrent users? The article I read at said there was a major difference in the number of concurrent users that BlazeDS would support vs LiveCycleDS.

    Hi Tretola,

    The difference in the scalability is because the BlazeDS is using the web server sockets and there is a limitation on the number of active connections a web server can have at a point of time. Even the browser has limitation on the number of active sockets. πŸ™‚

    Are you sure that RTMP is supported with BlazeDS? I downloaded blazeds_b1_121307 and blazeds_b1_020108 and cannot find any references to supporting RTMP at all. Your list seems to indicate it is supported, just not RTMP/T.

  8. Kevin says:

    Quick Followup. The official word from Adobe on BlazeDS and RTMP is :

    What capabilities are being released as open source?
    Adobe is contributing the core and proven Java remoting and HTTP-based publish and subscribe messaging technologies to the community under LGPL v3.

    This is a long way to say no. RTMP is not HTTP-based so it is not supported in BlazeDS.

  9. Sujit Reddy G says:

    Hi Kevin,
    RTMP is not supported in BlazeDS. Please let me know Which feature in the list indicates that RTMP is supported by BlazeDS.

  10. Kevin says:

    Sure. They way I read the “Real – Time Data” section under Blaze DS has two smileys for “Publish and Subscribe messaging” and “Real -time data quality of service”. I think the term “Real Time” led me to believe this was publish and subscribe and qos over true full duplex / non-polling channels (i.e. RTMP).

    I can see how you might argue that “Real Time” can be done w/o RTMP (like with long polling) but I think the subtlety there (and the fact that Adobe doesn’t really come out and say “no RTMP in Blaze) threw me off.

    Your list is great (thanks) but I think it might be clearer to indicate somewhere that LCDS has RTMP and BlazeDS does not.

  11. Sujit Reddy G says:

    Kevin, thanks for the suggestion πŸ™‚ I will update my blog to reflect that. πŸ™‚

  12. Sujit,

    you say that webtier compiled is available within BlazeDS but in the current build it doesn’t seem to provide one.

  13. Sujit Reddy G says:

    Yes, the webtier compiler is not available with BlazeDS. But you can still use the webtier compilation feature by downloading the installer from the URL below. As the feature can be used even without LCDS, i did indicate that webtier compilation (as a feature) is possible using BlazeDS.

    Hi Sujit,

    I’m still confused if the BlazeDS AMFEndpoint (non-streaming endpoint) uses the underlying NIO support from the application server (I’ve seen a couple of claims AMFEndpoint does support the underlying NIO).

    To me this confusion arises as LCDS has an AMFNIOEndpoint, which makes me believe AMFEndpoint is synchronous.

    Do you have information on this?


  21. Hi Alexander,

    AMF Ednpoint in BlazeDS will depend on the web server connection pool and so its up to the web server how it is handled. LCDS has an AMF NIO Endpoint, which will not depend on the web server connection pool. Both these end points handle requests in individual threads.

    Hope this helps.

    I have a problem. I am using messagePerformanceUtils to measure the total time and serverresponsetime. When i was using java 1.5 as middletier and flex 3.2.0 i was getting correct response time. But i moved to Java 1.6 the response time received in totaltime method of MessagePerformanceUtils come as 0. So that total time value comes as a negative number. Is there any compatability issue of Java 1.6 with Flex 3.2.0 and LCDS 3.2????
