Rammohan,
Can you connect to Oracle throught SQL Plus? This will narrow down if it a connection problem or a datasource problem.

Thanks Jeanne Boyarsky ,
I was away for awhile,

I am able to connect through SQL PLUS.

I need to know if the connection works proper through WSAD.

Let me know please..

Rammohan,
I am using Oracle through WSAD and it works fine. So the problem is something in the datasource configuration. Double check your driver, URL connection string, password, etc.
