Problem getting DB Connection from Datasource in OpenEJB

[Rajul Konkar]

Hi

I am having problem getting DB Connection from Datasource
though I can get the DB Connection using DriverManager using same credentials : url/name/password
I get the datasource object using JNDI, but when i try to get Connection from datasource object, It gives following error :

Caused by: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

Hello,
Please share how you have configured the Datasource.
I believe it must be done on Tomcat.
It might give us a clue.
