Hi,
I'm getting the following IOException while trying to connect to the DB from my web application using connection pooling.
Io exception: The Network Adapter could not establish the connection
But, am able to connect to the same DB from my Eclipse using the same following oracle thin driver statement.
jdbc 
racle:thin:@<server>:1521:<instance name>
I've also tried replacing the server name with ip and also with fully qualified dns name. But nothing worked.

Please help.
