Named queries with dynamic entities? [message #992011]

Hello everyone!

The question is in the title Razz

I have some dynamic entities and I want to have named query on them.
The problem is that my dynamic entities are created after my spring context is fully loaded so EclipseLink does not know them at startup.

Is there a way to create dynamic entities at startup before compilation of the named queries? Very Happy

I tried to look at Session customizers but I didn't find how to get an entity manager from a session.

Solution found!

public class AuditCustomizer implements SessionCustomizer{
	@Override
	public void customize(Session session) throws Exception {
        	DynamicClassLoader dcl = DynamicClassLoader.lookup(session);
        	DynamicHelper helper = new JPADynamicHelper(JpaHelper.createEntityManagerFactory(session.getProject().createServerSession()));
		...
	}
}

and add this to your persistence unit :

<property name="eclipselink.session.customizer" value="<full package>.AuditCustomizer"/>
