Exception during lookup of object *defaultPMF, cannot resolve object ref

[kumarkk]

Hi,

We have a EJB built on 7.0 which was working fine. After migrating to 7.3 when I run the application it is throwing the below exception;

javax.naming.NamingException: Exception during lookup operation of object with name ejbContexts/.........../JDODataManagerBean/java:comp/env/jdo/defaultPMF, cannot resolve object reference. [Root exception is com.sap.engine.services.connector.exceptions.BaseResourceException: ConnectionFactory "" does not exist. Possible reasons: the adapter in which ConnectionFactory "" is defined is not deployed or not started.]

The status of below in NWA are green;

1) JDBC data source alias

2) jdo/defaultPMF-com.sap.jdo.jca.spi.SAPJDOManagedConnectionFactory (JCA managed connection factory)

3) jdo/defaultPMF (Resource)

Code:

			Context ctx = new InitialContext();
			PersistenceManagerFactory pmf = (PersistenceManagerFactory) ctx.lookup("java:comp/env/jdo/defaultPMF");
			pm = pmf.getPersistenceManager();

Apparently in the above error message, it is not showing which ConnectionFactory it is looking for (it just says "") so i can check the connection factory as well as the adapter in which the connection factory it is defined.

Can anyone please advise?

Any thoughts ?
