Embeddable Ejb problem

[ramanap]

When I tried to run Entity Bean from Stateless session beans using Embeddable Ejb, I get the following error:

Did you ever figure this out or get an answer? I have the same problem "all of a sudden" EJB3 CMP entity beans are failing with the same error you had " javax.ejb.EJBException: java.lang.IllegalArgumentException: Unknown entity: __" when I call em.persist(MyCMPBean) from the session bean. Don't think it matters but... the Session Bean is a Stateless EJB as a webservice. All beans are done with annotations.

Maybe this will help anybody in an web environment (Persistence Manager is not synchronized and not intended to use in Multithread environments)
