Retrieving remote EntityManagerFactory from jndi (ex: for JUnit test)

[taccart.thierry.accart.name]

Hi

I've build a 'basic' seam project, and added an open API  - mainly DAO and tools-  to offer possibility to external tools to access it.

The API is by default seting up the entityManager via 

((InjectedEntityManagerFactory) new InitialContext()
  .lookup("xxxEntityManagerFactoryName"))
  .createEntityManager());

I started to build the JUnit test for my API and I'm facing a problem ... that many people are facing, without solution.

In my JUnit test, I need to setup the EntityManager via somethting like

Properties env = new Properties ();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");
try {
  Context ctx = new InitialContext(env);
  EntityManager em = ((InjectedEntityManagerFactory) ctx
    .lookup("java:/myprojectEntityManagerFactory"))
    .createEntityManager();     
}
(...)

Of course, the JBoss server is started, EAR is deployed, and  persistence.xml sets up the java://myprojectEntityManagerFactory via

 <property 
  name="jboss.entity.manager.factory.jndi.name"
  value="java:/myprojectEntityManagerFactory" />

Trying to retrieve the EntityManagerFactory always throws a naming exception

javax.naming.NameNotFoundException: myprojectEntityManagerFactory not bound
     at org.jnp.server.NamingServer.getBinding(NamingServer.java:542)
     at org.jnp.server.NamingServer.getBinding(NamingServer.java:550)
     at org.jnp.server.NamingServer.getObject(NamingServer.java:556)
     at org.jnp.server.NamingServer.lookup(NamingServer.java:296)

     at javax.naming.InitialContext.lookup(InitialContext.java:351)
     at org.my.test.myprojectTest.prepare_Tests(prepare_Tests.java:48)

Has anybody an idea on how to retrieve the EntityManagerFactory from remote Jboss (jnp://127.0.0.1:1099 ?)
Any idea for a workaround to test the API ?
