i have jboss-5.0.0.Beta2

i deployed jar(hot deployment) with ejb3 session bean and jpa entity. i.e i pasted the jar file when the server is running. it worked fine.

i modified the session bean, created same jar and deployed again(hot).

but it is throwing exception. what is the procedure for re-deployment ? pls help to understand.
