Shelby and Karl on EJB, J2EE, and XMT in JBuilder 2005

Listen to the audio replay.

This is a log of the chat room during the live audio chat from January 31, 2005 on JBuilder 2005 with Shelby Sanders and Karl Ewald. They discuss EJB support, targetting EJB servers, the EJB designer, and XMT in JBuilder 2005.

Note: This log is only the chat room transcript. There is much additional information covered in the audio replay that is not available in this chat log. For all previous and upcoming live chats, see http://bdntv.borland.com/chat.html.

aohlsson: As John announced, feel free to use /ask or the "ask" button at any time to submit questions for Shelby. Thanks!

aohlsson: Karl just joined us, so now you can feel free to ask him questions about the EJB designer as well. :)

jkaster: kensipe: "Is the XMT API documented in the OT docs?" - Shelby: it is in the help now, and we definitely want to hear about anything that's missing.

jkaster: doychin: "Is there support for converting application from one Application server to another? If I have Jboss based application how much of jboss specific descriptors are converted to the corresponding custom descriptors for the other server I need to target?" - Shelby: Say you have an app on Weblogic you want to take to JBoss. A lot of the descriptors are common to both. One of our test scenarios is taking everything from CMP and moving from server to server to server.

jkaster: kensipe: "are you looking at geronimo" - Shelby: we're watching it and trying to keep up with the various changes. With the first run of a server, particularly in the Open Source world, it's hard to tell how stable it's going to be. So we need to watch its development, have an idea to support it, and we're trying to collect market data on what servers people are using in development and production.

jkaster: doychin: "The JBoss support is superb ;-). Great work ;-)" - Shelby and Karl: thank you very much!

jkaster: doychin: "Is there specific way of making few app servers supported in the same project with same source code? So when I change something in the module for JBoss this change is propagated to the descriptors for the other server." - Shelby: We have baseline support for multi-targeting, so it should be possible. We haven't seen the demand yet to implement this ourselves.

jkaster: doychin: "Why is the Bean properties windows in EJB designer are not resizeable?" - Karl: (laughs) good question. I don't remember getting this request before.

jkaster: doychin: "Karl said that he is working on EJB designer redesigning. How much will this going to affect the performance?" - Karl: The EJB designer is always in flux. I'm certainly looking at ways to change the performance characteristics. From JBuilder 6 to 9 we made major changes to improve performance.

jkaster: kensipe: "how does jb handle developers working with jboss and then packaging for a WAS deployment" - Shelby: That is still multi-targeting. What we have heard of people doing is taking a snapshot of a project, putting that project in a separate workspace, then re-targeting it to another server.

jkaster: kensipe: "adding resource ref / ejb refs seems difficult... is there another way of managing this outside the structure pane?" - Karl: I think that's the only mechanism we provide right now. That's been on our perennial list since JBuilder 6.

aohlsson: We're running low on questions. Feel free to feed us a few more questions on today's topics. Thanks.

aohlsson: doychin: "there is JSR for pay API http://jcp.org/en/jsr/detail?id=182" - Thanks!

jkaster: doychin: "Do you think will be good idea to make as open source EJB designer for JBoss?" - Do you mean an open source plug-in for the EJB designer?

jkaster: doychin: "Can generics in Java 5 be used with EJB designer now?" - Karl: It would be outside of the EJB standard code signatures. Inside your own code, it's all based on JAM/JOM. Java Abstraction Model (ro) and Java Object Model (r/w)

jkaster: kensipe: "as we look to move to EJB3, are you looking a hibernate mapping tool or jdo mapping" - Shelby: We're actually looking at a lot of persistence frameworks. We're trying to pick the winning one. Both of those are candidates.

jkaster: doychin: "Open sourcing the JBoss plugin" - Karl: Certainly, that goes way beyond the EJB designer, which is a small piece of that support. Shelby: We've had that proposal kicking around since JB 7.

jkaster: doychin: "Great chat" - Thanks!
