Hi experts

I have a problem in injecting EntityManager when I have multiple ejb module in my ear file. Actually, only in one EJB module I need the EntityManager and the others are only a bunch of stateless business object.
there is no persistence.xml in any module except the one that needs EntityManager. the code I am using is:

private EntityManager entityManager

but during the deployment the container complains that could not set the em.

I have test with and withour unitName attribute but no success.

the thing is when I make all my classes into one jar file and declare it as an EJB module in the application.xml everything is OK.

I am using TopLink and Sun Glassfish v9.x

I am really stuck any help would be appreciated

Regards, Mohammad

By the way, I eventually end up to injecting EMF as the following code

private EntityManagerFactory emf;

private EntityManager em;

public void construct(){
em = emf.createEntityManager();

public void destroy(){

but this is not good nor does it work fine

please help me
