Unable to lookup EntityManager in 4.0.3 SP1 with EJB3 RC4-PF

[donniedarko]

Im trying to convert our RC3 apps to RC4-PFD but I cannot get EntityManager lookup through JNDI to work. Similar posts have already been posted , but I have read them and none have concluded with an answer to this.

The following persistence.xml registers my entitymanager in JNDI just fine.

<persistence>
 <persistence-unit name="test">
 <jta-data-source>java:testDS</jta-data-source>
 <properties>
 <property name="jboss.entity.manager.jndi.name" value="java:/EntityManagers/testEM"/>
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/EntityManagers/testEMFactory"/>
 <property name="hibernate.hbm2ddl.auto" value="update"/>
 <property name="hibernate.show_sql" value="false" />
 </properties>
 </persistence-unit>
</persistence>

So far so good and I can see in the JNDI view service in JMX-Console that it is registred correct

java: Namespace
EntityManagers (class: org.jnp.interfaces.NamingContext)
 | +- testEMFactory (class: org.jboss.ejb3.entity.InjectedEntityManagerFactory)
 | +- testEM (class: org.jboss.ejb3.entity.InjectedEntityManager)

, but when i try to look it up it just returns null....

EntityManager em = (EntityManager)ctx.lookup("java:/EntityManagers/testEM");

No exception...nothing..the "em" variable just gets set to null.

I cannot reproduce the problem. Our testsuite does *actually* test this stuff you know.

I need more information. Are you sure something else isn't null?

I have the same problem.

I can also see the JNDI entries of my "EntityManager" and "EntityManagerFactory" inside the JNDI view service but when executing the JNDI lookup method the same error occurs: em or emf are null!

..well... you might have test suites that tests all possible aspects of this, and probably I'm not adopting the "new" RC4_PFD ways of doing things correctly ... but I have set up a new JBoss IDE project for the sole purpose of reproducing the issue. I have uploaded it to the following url:
http://www.lightminds.com/ShowDocument.asp?id=735
To reproduce the issue just point your browser to http://localhost:8080/testentitymanager/test and set a breakpoint
withing the getEntityManager method of the com.lightminds.test.EntityManagerStoreBean class and step. You should see that the looked up entity manager will become null.

Please tell me if this is an error in my setup/ usage error and in that case shouldn't it at least throw an exception instead of just returning null?

Best regards

[bill.burke]

ok, i'll try it out.

Bill,

What was your foundings on this...?

Best regards

Same problem here.

Actually, the JNDI lookup works... the injection using @PersistenceContext(unitName="foo") does not.

[donniedarko]

Rorschach...If you got my test project to work...what exactly did you do? You are not saying that you got it to work with my setup unmodified on 4.0.3 SP1 with EJB3 RC4-PFD are you?

Bill... what was your conclusion running the test project as described?

[rorschach]

Please disregard, my issue was on 4.0.4.
