Hello,
I am Oracle employee in Ottawa. I have defined <persistence-unit-ref> in
ejb-jar.xml, just like the following (part of ejb-jar.xml):
<enterprise-beans>
<session>
<ejb-name>ServerSideTestHelper</ejb-name>
<home>oracle.toplink.essentials.testing.ejb.testframework.ServerSideTestHelperHome</home>
<remote>oracle.toplink.essentials.testing.ejb.testframework.ServerSideTestHelper</remote>
<ejb-class>oracle.toplink.essentials.testing.ejb.testframework.ServerSideTestHelperBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<persistence-unit-ref>
<persistence-unit-ref-name>persistence/myPersistenceUnit</persistence-unit-ref-name>
<persistence-unit-name>ejb30_Advanced</persistence-unit-name>
</persistence-unit-ref>
</session>
</enterprise-beans>
But when I try getEntityManager using this persistence-unit-ref-name to
lookup, I got *javax.naming.NameNotFoundException*. The following are
segment of my code:
public EntityManager getEntityManager(){
EntityManager em;
if (this.entityManager == null){
try{
Context ctx = new InitialContext();
this.entityManager =
((EntityManagerFactory)ctx.lookup("persistence/myPersistenceUnit")).getEntityManager();
}catch (NamingException ex){
throw new TestException("Unable to look Up EnityManager
:" + ex.toString());
}
}
return this.entityManager;
}
Would you mind to point me if I could getEntityManager like the above?
Thanks a lot,
Kevin
