I've been over this a hundred times in at least 20 different approaches. I don't know what happened, but my EJB3 entities stopped working. I now get org.hibernate.MappingException: Unknown entity all the time. If I reconfigure things I get other errors, but it never works.

I have a .par file that has my User class. It is annotated properly and the persistence.xml file looks like:

<entity-manager>
 <name>myManager</name>
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:com.me.dsn.myDsn</jta-data-source>
 <class>com.me.entities.User</class>
 <properties>
 <property name="hibernate.dialect"
 value="org.hibernate.dialect.SQLServerDialect" />
 <property name="hibernate.hbm2ddl.auto" value="none"/>
 </properties>
</entity-manager>

In my SLSB, I used to be able to call:

Query q = em.createNamedQuery("UserSelect");
q.setParameter("userId", Integer.valueOf(userId));
User user = (User) q.getSingleResult();

UserSelect is a NativeNamedQuery defined in my User entity. This suddenly and mysteriously stopped working...mybe my upgrade to SP1 had something to do with it. Using this call I get:

15:48:23,625 INFO [STDOUT] javax.ejb.EJBException: null; CausedByException is:
 Named query not known: UserSelect

So, I thought maybe something changed. I altered my SLSB code to:

Query q = em.createNativeQuery("{call svc_user_select(:userId)}",User.class);
q.setParameter("userId", Integer.valueOf(userId));
User user = (User) q.getSingleResult();

Now I get:

15:50:17,794 INFO [STDOUT] javax.ejb.EJBException: null; CausedByException is:
 Unknown entity: com.me.entities.User

Further in the stack trace it shows a org.hibernate.MappingException: Unknown entity error. There is no information more informative than this. However, I can see in the JBoss console that the enity deploys without error. Why is it unknown? I have been running around in circles chasing this error all day, literally! Any help would be GREATLY appreciated.

Thanks,
