Hi Sahoo,
I tried add ejb-jar.xml file to my EJB Module.
But still doesn't work.
I put ejb-jar.xml file into WEB-INF, is it right?
I need to look up the SimpleBean from the SimplePOJO because my SimplePOJO
contains an entity manager:
@PersistenceContext (unitName="Test_Sample1-ejbPU")
private EntityManager em;
Is there another way to create SimpleBean?
If I do:
SimpleBean bean = new SimpleBean();
The EntityManager (em) has not been injected and is null.
Angelo.
