How to get the TransactionManager in a stateful EJB (using JPA toplink)

Question

I use weblogic 10.3
This is my stateful EJB and I need to get the TransactionManager because I want to suspend my transaction...
Here it is ok for the UserTransaction ut but I got an error with the TransactionManager
EJB Code
//@Stateless(name = "MyFacadeEJB", mappedName = "MyFacadeEJB")
@Stateful(name = "MyFacadeEJB", mappedName = "MyFacadeEJB")
@TransactionManagement(TransactionManagementType.BEAN)
@Remote
@Local
public class MyFacadeEJBBean implements MyFacadeEJB, MyFacadeEJBLocal, Serializable {   
@Resource javax.transaction.UserTransaction ut;
@Resource javax.transaction.TransactionManager tm;
Error Message at the deploy EJB
Unable to deploy EJB: MyFacadeEJB from PocJTA-PEJB-ejb:
[EJB:011026]The EJB container failed while creating the java:/comp/env namespace for this EJB deployment.
weblogic.deployment.EnvironmentException: [EJB:010176]The resource-env-ref 'test.ejb.MyFacadeEJBBean/tm' declared in the ejb-jar.xml descriptor or annotation has no JNDI name mapped to it. The resource-ref must be mapped to a JNDI name using the resource-description element of the weblogic-ejb-jar.xml descriptor or corresponding annotation.

Chpruvos,
Hi, I ran into a similar issue when specifying WebLogic specific descriptors in ejb-jar.xml and the corresponding weblogic-ejb-jar.xml. I no longer use this approach in our example code - we just use annotations. see: http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial#Tutorial_Source
My session bean is stateless - I don't know how much it will help with your statefull bean managed config but here are copies of the ejb.jar configuration xml I used to use. All the resource*ref elements (see the resource-description* element) ended up in the weblogic specific weblogic-ejb-jar.xml descriptor file.
ejb-jar.xml
