Thanks Chris, After messing around with JNDI yesterday I came to the same conclusion that Tomcat is doing some isolation and I can understand why. I will look into the JMX approach you suggest as I am running out of options. If That doesn't provide a solution I think I will have to deploy our connection pool logic to the shared 'tomcat/lib' directory where static collections will be available to all contexts. Do you see any issues with deploying code within the lib directory?
