Java Database Connectivity (JDBC)

Hello,

Iam trying to connect to a oracle database from websphere through datasource (connection pooling). Iam geting the following error
Unable to get a PooledConnection from the DataSource. and
The Network Adapter could not establish the connection

Can someone kindly send a solution for this issue
