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
