jars in Lib directory within a .EAR is copied to every .WAR

Hi,

I have a .EAR with about 15 wars. When the .EAR is deployed, I found out from server.log, any jars in the webapp.ear/lib are copied "number of .war" times by the jboss main deployer. Say for example, I have jdom.jar in webapp.ear/lib, and the jdom.jar is copied to the lib directory of every single .WAR during deployment. Is this a bug? Or am I missing something?

Thanks

1) don't post on the _design_ forum --> use _user_ forum
2) give more info: what JBossAS, JDK, ...

Let me give a guess:
- for JBossAS 4.x that's expected
- for JBossAS 5.0 that's expected, but can be changed

The issue here is how to handle nested jars.
It's the file-system framework that knows how to handle it.
Using just JDK stuff requires to unpack things.
With new VFS you can do much more.

Hi, thanks for reply, I am on JDK1.5 and Jboss4.2.2GA

So is there anyway I can get jboss4.2.2 not to duplicate the jars?
