Hello, I created an EJB that uses a resource adapter that I created. It works fine in Glassfish, but while trying it in Websphere 7.0 I am getting the following error:

Exception in thread "P=355599:O=0:CT" java.rmi.RemoteException: CORBA UNKNOWN 1229127302 Maybe; nested exception is:

Java Result: 1

My EJB is trying to retrieve the connection factory with the following code:

// retrieve the application server naming context (JNDI)
initctx = new InitialContext();

// retrieve the connection factory
connFactory = (ConnectionFactory) initctx.lookup("eis/myConnFactory");

Do you have any idea about what is wrong?

Thank you

Enrico
