I trying to get a EntityManagerFactory from a POJO using this code:

private EntityManagerFactory emf;
....
emf = Persistence.createEntityManagerFactory("fonocontrolDatabase");

but when I run the app I get and Exception.

I'm using Seam with the embedded microcontainer in a Tomcat server so
I think the problem is with the tomcat JNDI beacuse the datasource its in the microcontainer and the method it's looking in the in the wrong enviroment.
