DataSource Problem

[9727604]

Hi all,
I am trying to access my database using a DataSource but I am encountering a problem and have tried in vain to find a solution(code snipet and stacktrace given below). I am using websphere application server and the database is Oracle 9i. I the server running. Any help would be greatly appreciated.

Thanks

String dsName1 = "jdbc/UpaidPool"; // JNDI name
DataSource ds1 = null;
Connection conn = null;

/**
* Construct an access object.
*/
public access ()
{
try
{
Context ctx = new InitialContext();
ds1 = (DataSource)ctx.lookup(dsName1); // Problem here

} catch (Exception e) {
e.printStackTrace();
}
}

I have added the appropriate jar files to my classpath and tnow the error seems to have migrated to the DataSource as opposed to the Initial Context. I now get a different error (Stack trace below). Any Ideas?
