I am having the same issue as 
h2.  http://community.jboss.org/message/517062#517062 Custom/Wrapped JDBC Driver for DataSource

I need to instantiate a data source connection pool with a proxy user and at the session level switch the connection on behalf of the authenticated user.
I have a jaas security realm implmentation to create a custom principle, 
I have a custom driver that wraps an oracle oci driver in order to inject properties from the custom principal configured in a a datasource 
the issue is that the custom jdbc driver when set in a -ds.xml is ignored and the driver-url is the only element used to make the connection. The custom driver is never loaded.

I am using Pete Bennett's example in
 http://community.jboss.org/docs/DOC-10049 http://community.jboss.org/wiki/IntegratingOracleVPDandJBoss with a custom JAAS realm

I have tried JBOSS 4.2 with JDK 1.6 on solaris
as well as JBOSS 5.0 with JDK 1.6 on solaris

The realm works, the datasource works, the application works, a custom jsp page can interrogate the underlying connection to see that it is a WrappedConnection  but the driver never loads and worse yet never errors out

I see the reference to a jms /jca configuration and I have tried to set up the message queue but I don't see how it applies to the problem Roland and I are encountering.  Is there a more fleshed out discussion regarding interrogating a principle to inject it's properties to the datasource driver?
