Subject Re: DBCP Registering a PoolingDataSource in JNDI
Date Mon, 02 Feb 2004 20:53:48 GMT
I created the following subclass:
class ReferencablePoolingDataSource extends PoolingDataSource 
implements Referenceable

and the exception goes away.

Tomcat initializas its JNDI tree using a Reference and a 
ObjectFactory, that's also a way to do it.
