When I am starting the server the server is showing that the connection pool is sucessful. But when I am trying to connect my client from command prompt , like this:

:\EJB\Bean2>java -Djava.naming.factory.initial=weblogic.jndi.TengahInitialConte
xtFactory fenb.Client t3://localhost:7002

It is showing the following error:

Caught exception!
