| | | Two phase commit transaction using WSAD5.0 and DB2 | Two phase commit transaction using WSAD5.0 and DB2 2005-04-27 - By Hrishikesh Barua

Hello,
You should cast the object that you look up to a javax.sql.DataSource object.
Using any proprietary APIs means your app will not run on any other appserver.
In this case the object that you get back from the lookup is a WAS datasource
wrapper - which is correct.
Declare
javax.sql.DataSource db2Datasource = null;
Regards
Hrish

InitialContext ctx = null;
DB2XADataSource db2Datasource = null;
Connection conn = null;
try {
