Problem while creating Oracle DataSource in WebSphere Studio version 5.x

[Pramod Pant]

I had been trying to create Oracle DataSource connection in WebSphere Studio Version 5.0. I created DS jdbc/LMSDriver and looking up the same with same name, but test server on WSAD throws the following exception.
I'll really appreciate if you solve this issue.Thanks a lot !!
