Hi there,

I have a simple query like this,
================================================
List<OrderSet> emps = em
.createNamedQuery("findDocSetByNameId")
.setParameter("nameID", this.orderNo)
.getResultList();

if (emps.size() == 0) {
throw createMsgStoreServiceException("Order is not in Message Stoer.");
}

OrderSet os = emps.get(0);
=================================================

When I run as a java application (JUnit case), everything is fine. But when I run via a web service hosted in a WLS 10.3.5, (I think my EclipseLink version is 11) I got an exception the the highlighted line saying can not case between the same java class.

following is the exception. Any help will be appreciated!!

Seems to be a class loader issue. Have you deployed that same classes/jar in two different places or apps?

Are you using a container managed or application managed persistence unit? If you are redeploying, ensure that you have closed the old EntityManagerFactory.
