how to move the jar from the war web-inf directory?

[frank yin]

hi,all
I'm using the Jboss-3.2.2 and I deploy some ears.
In one ear, there is a war, and in this war's web-inf directory, there are some jars which have existed in the other ears. I just want to remove these redundant jars from the war/web-inf/lib, but if I do so, when jsp compiling, jboss give the error of no class found exception.
Is there some way in jboss that in the war, it can share all the jars in the other ears? how can I config this feature?
Thx
