The finalize method in the struts sessionImpl logs an "unclosed connection" warning in this JSP application I have running in Tomcat. I use C3p0 for connection pooling and obviously if I close the connection myself it will break the application. Has anyone out there ever encountered this? My Oracle server confirms that these connections are left open and inactive after I'm done. So clearly there has to be something I can do?

You're pretty vague but do you session.close() somewhere
