Subject RE: [dbcp] Call Oracle stored procedure via DBCP?

If you need to get the underlying connection,

((BasicDataSource) dataSource).setAccessToUnderlyingConnectionAllowed(true);

Before you can getConnection.

That's because you're assuming that dbcp returns you a naked vendor JDBC 
Connection object. It doesn't - it returns you a pooled connection 
wrapper with forwarding methods.  Ditto for CallableStatements.

If you really needed to get the underlying object, you'd have to look at 
the JavaDoc for DBCP.
