Du you have classes12.jar or ojdbc14.jar available in ur Lib file system of server running on windows 7?

From error it looks that your driver classes are not loaded, take the class12.jar or ojdbc14.jar (client driver), put them in IS/lib/jars and restart the IS… if you still face the issue then your driver might be incorrect. Try to get the drivers jar from the DB server installation directory.

I fixed the issue. i have got new classes12.jar and placed in Integration server/lib/jars. Now it is connected.

Thank You very much
