DataSource Connection in WSAD

I have problems in connecting to the Database using Datasource. Previously i was using VAJ3.5 there the connection to local UDB is working fine with "COM.ibm.db2.jdbc.app.DB2Driver". But now when i use the same driver iam getting the following exception while the Entity bean(BMP) is being loaded into the local test Environment.
ERROR:

java.sql.SQLException: CONM7005E: The class (COM.ibm.db2.jdbc.app.DB2Driver) does not implement javax.sql.ConnectionPoolDataSource or javax.sql.XADataSource

Please help me to sort out this problem.
Thanks a lot in Anticipation.

This will need to be moved to the IBM/Websphere forum, but what version of WSAD are you using? They're different.

Iam using WSAD4.0. Now iam testing my application in WSAD4.0 Test Environment.

Did you add db2 to the classpath for your EJB project? It's one of the predefined variables, but you need to explicitly include it. Otherwise, you get lots of classpath issues.
Also, check whether the EJB project is set up to use the same server as the one that you set up the datasource on.

Thanks Jeanne and David for your interest.
The problem is solved when i changed the DB2 driver to COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource
Now it's working fine.
