Hello,

For example, I have two jars:

1. JpaLib.jar, which contain entity class (for example, Account) and persistence unit JpaLibPU.

2. JpaBean.jar, which contain ejb3 SLSB, which uses JpaLibPU to get Account from database.

@Stateless
public class JpaTestBean implements ...
{
    @PersistenceContext(unitName="JpaLibPU")
    private EntityManager em;

    public Account getAccount( String id )
    {
         return em.find( Account.class, id );
    }
}

After deploy, all works ok.

When I redeploy JpaLib.jar (add another entity class, for example), JpaBean.jar is stopped and started again, when JpaLibPU becomes available.

But, when I invoke getAccount I get exception: "java.lang.ClassCastException: tst.entity.Account cannot be cast to tst.entity.Account". As I understand, this happens due Account in JpaBean.jar and Account in JpaLib.jar loaded using defferent classloaders.

If I manually "touch" JpaBean.jar - jboss redeploy it and all works fine again.

How can I force JBoss to automatically redeploy (not just stop/start) JpaBean.jar when JpaLib.jar is redeployed?

Any ideas?

PS: JBoss version 5.1 or 6 M2
