Moving web-application from WebLogic 10.0.0 to 10.3.3 - EJB Exception

Question

Hello all,
I've moved my web-application from weblogic 10.0.0 to the new platform with Weblogic 10.3.3. After this I had some JMSEceptions (unable to run JMS methods inside of servlet or EJB) and they were fixed. For now I got new exception:
####<07.12.2012 16:03:06 FET> <Info> <EJB> <pc-XXXXXX> <AdminServer> <[ACTIVE] ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <BEA1-00340877198035A73969> <1354885386932> <BEA-010227> <EJB Exception occurred during invocation from home or business: weblogic.ejb.container.internal.StatelessEJBHomeImpl@14df37f threw exception: javax.ejb.EJBTransactionRolledbackException: EJB Exception: : java.lang.ClassCastException: com.XXX.XXXX.XXXXXX.persistence.OperatorBean cannot be cast to com.XXX.XXXX.XXXXXX.persistence.SwitchboardBean

@Entity
public class OperatorBean extends OwnerBean
@ManyToOne(optional = true, fetch = FetchType.EAGER)
private SwitchboardBean switchboard;
@Entity
public class SwitchboardBean extends OwnerBean
@OneToMany(mappedBy = "switchboard", cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
private List<OperatorBean> itsOperators = new ArrayList<OperatorBean>();
Seems that it happened due to updating weblogic version (changes in jee, jms, ejb, jpa versions?). Could you please advice me how to fix this issue?
Thanks, Ilya

Answer 1

I belive there is no problems for this change, because the versions are the same for java at least for OaS, for weblogic you should see documentation. I think you can try deploying you app to new environment if you get any noclassdeffound error or something like it then you could have problems for versions.
