RE: EJB-iSeries - Please HELP!

I am stuck with this problem in connection to Database.  Can someone
please help me resolve this issue?  

When I do the default (clouscape) where the tables are created as
default, I am fine but as soon as I create a Database of my own in a
folder and point this to Database, my EJB gets the
java.rmi.RemoteException: ; nested exception is:
java.lang.NullPointerException.  I can insert, update and delete the
rows from Data perspective though with the same connection.  I have also
checked the JNDI which matches with the Datasource that I created i.e.
jdbc/ds1 which points to my database.

I have the same problem with AS/400 database connections as well.  

Is there a sample code or some more information that will help me
resolve this issue?

Thanks,
Sudha

I have pasted my error as it appears on the console.   This happens when
I initialize(call create() method) and then do a work with objects and
call my getFirstName(int id) method.  This method is defined as public
in the interface.

Thanks for your help,
Sudha
