Siva,
The DataSource class supported is com.ibm.db2.jcc.DB2DataSource. If you are using JCC driver, the connection parameters should look like this
Transaction Type LOCAL_TRANSACTION
DataSource Class com.ibm.db2.jcc.DB2DataSource
serverName
user
password ******
databaseName
portNumber <Port#>
networkProtocol
Other Properties driverType=4
Hope this helps
