9iAS Connection (DataSource) Pooling

Question

We are having difficulty getting 9iAS DataSource Pooling to work. We are using 9iAS 9.0.3 (without Infrastructure) and, as per the J2EE Services Guide, have :
1) Added...
Context ic = new InitialContext();
DataSource ds (DataSource) ic.lookup("jdbc/OracleDS")
Connection con = ds.getConnection();
...to our code.
2) Modified the default DataSource's url, username, password, min-connections & max-connections from within Enterprise Manager (leaving ejb-location as is at "jdbc/OracleDS") and restarted the Instance.
The app generates an exception when trying to locate the OracleDS, however.
We have also tried replacing the "com.evermind.sql.DriverManagerDataSource" class with "oracle.jdbc.pool.OracleConnectionCacheImpl" as per another post's recommendation.
It appears that others have had similar problems (prior to 903?), but many have, in fact, (now) got this working successfully -- what are we missing please......?
Thanks.

Can you run the server with -Djbo.debugoutput=console property set on the vm command line and send us the detail exception, if any, thrown on the server console.
