Re: [eclipselink-users] eclipselink-users Digest, Vol 62, Issue 1 
Trying using the JPA entityManager.unwrap(Class) API.
If that does not help, there are some methods in our org.eclipse.persistence.jpa.JpaHelper class that may help.

Hi Tom,

Thanks for the prompt reply.

I have found the root cause of the issue but need your advise/recommendation on
how to resolve this.

We have the EntityManager injection working on the EJB and inorder to try to
call a storedproc we have been
doing the following steps before injection was working.

final Session session = ((EntityManagerImpl) em).getActiveSession();
session.executeQuery(query, args);

But now since the injected entitymanager is of type
com.ibm.ws.jpa.management.JPATxEntityManager
we are getting java.lang.ClassCastException.

In this scenario what is the best approach to invoke a storedrpoc?

Regards
Gibi

    Hi,

    I am using Websphere 7.0.0.23 with EclipseLink 2.2.1, getting the following
    exception

    java.lang.ClassCastException: com.ibm.ws.jpa.management.JPATxEntityManager
    incompatible with org.eclipse.persistence.internal.jpa.EntityManagerImpl


    I have tried setting the property

    eclipselink.jpql.parser=org.eclipse.persistence.queries.ANTLRQueryBuilder.
    but it has not helped.

    Also have tried using 2.3.3, but did not work.

    Regards
    Gibi Luckose
