Hi, Why go through all this? The point of the JNDI Resources part of the Servlet Specification is to allow portable interaction with external resources. Your approach loses all the portability (it's Tomcat-specific) without gaining much of anything. You could do the same stuff in your webapp, instead relying on a portable notification of app shutdown (ServletCotnextListener) and managing your own object creation/destruction.
