error at the place "home.create()"

[Ravisankar.N]

Hi,   I got a doubt in websphere 4.0. I am able to deploy and run a session bean in the websphere 4.0. But while in the entity bean it deploys sucessfully. But while contacting from the client it gives error at the place "home.create();". I think the data base mapping is the problem. Where to give the mapping.   Well, thanks a lot in advance. Ravisankar
