Is it possible to get the entity manager from a servlet? I am using JBoss-Seam
CVS and running it on Tomcat under the ejb3 container. I am trying to integrate
support with PayPal and have written a servlet to catch the call from paypal.
In that method I want to get access to my PayPalTransaction object to persist a
new object/record to the database.
What I tried:
UserTransaction utx = Transactions.getUserTransaction();
| utx.begin();
| try
| {
| EntityManager entityManager = (EntityManager)
|
Naming.getInitialContext().lookup("java:/EntityManagers/entityManager");
|
I also tried "java:/entityManager" and just "entityManager"
The lookup is failing.
Error I got:
javax.naming.NameNotFoundException: EntityManagers not bound

Is it possible to do this outside of the faces context?
Thanks,
