I too have a similar problem - I have a helloworld Session Bean which has
only one method, sayHello(String) and the client and the bean work just
great in VAJ and Websphere testenvironment, but when I deploy it to
websphere and try to run the client, either from VAJ or from command line, I
keep getting this nullpointer exception, which I couldnt trace the source...
lookup seems to happen properly, the object returned is of proper type.
Message : RemoteException occurred in server thread; nested exception is:
com.ibm.ejs.container.UncheckedException: ; nested exception is:

EJB in Websphere app server
Dear Aditya
I could't get you?
In normal deployment (which I have done several times for web clients eg
servlets in WebSphere),i dont expose specific method of EJB during
deployment.
Any way if it's reqd in case of stand alone client ,how it's done in
WebSphere?
thanx for your reply..
