Hi, All:
I am trying to setup the MusicCD store from IBM's tuto on EJB's. I have finished the deployment w/o error, and am trying to run the client to get run it. Both clients talking to EntityBean and SessionBean have errors. But I think they are related so only show the error of the EntityBean here. I have confirmed that the following codes run successfully:

I got the home stub using JNDI lookup. But then when I tried to use the home to run methods. I got the following. Any Ideas?

I found the problem, it was with DB config. Nothing to do with EJB. The error reporting was indirect so kinda of misleading ...
