Hot-deployment of java files

[Wouter Oet]

Hi Francesco,

During JFall 2009 I attended a presentation by Arun Gupta about J2EE 6 and Glassfish v3. He talked among other thinks about hot-deployment of java files with glassfish. Currently I'm doing the same with JBoss AS and Seam however I was wondering if JBoss AS will be going to support this feature for J2EE 6. Because it drastically shortens the develop-compile-test cycle which makes it much easier to work with.

Thanks,
Wouter

Not that i know. However, Seam 3 has some plans for supporting this for Seam beans.

That´s too bad. I really hope that it will be implemented.

How?

[Wouter Oet]

Because the class is replaced at runtime and therefor no need to re-deploy the application.

Hi Wouter,
sorry for replying too late to your question. I'm not really sure if I understand your query, however if you refer to hot-deployment of applications this can be already be done, provided that you're using an exploded file format: for example in an exploded .war application you can hot-deploy partially your JSPs/Servlet without the need to stop/start the application.
Hope this was the meaning of your question.....
regards
Francesco

I am still not understanding how development cycle can be shortened due to hot deployment.

I can make out that it helps deployment and I have used that when I deploy on JBoss. But I do not necessarily think development cycle is affected
