Hello Pradeep,
Check this note:
#1138877 - PI 7.1 : How to Deploy External Drivers JDBC/JMS Adapters
And also the FAQ of JDBC, note #831162.

Hi,
What kind of class is "XXXXXXXXXXXXXXXXXXXX" ? A custom JDBC driver ? A JDBC lookup wrapper ? Did you deploy the JDBC drivers according to SAP official how-to guide (search for it in SDN) ?

Are you running XI or PI (in PI, it's easier to add new JDBC drivers, everything is done thru the NWA tool, but you need to be authorized to use it) ? In XI, I can't remember exactly, but deployment means some JARs at file system level ...
But if drivers weren't deployed, you should get another sort of exception (not the ClassCastException) ... Btw, for ORACLE, your datasource needs to be set up as "Vendor SQL"
