I've followed the advice from Romain about trying to use place holders, and set up a LifecycleListener (see 2 posts down).
However, whenever I try to load context.xml with my listener in, it is either getting ClassNotFoundException (I assume because its in the wrong place for the right ClassLoader), or it is apparently ignored. So I am guessing that context.xml for my app is not being loaded. I've attached a simple project which should print out stuff when constructing or using my Listener. Currently the context.xml ends up in WEB-INF/classes/META-INF whichI *think* is the correct place. Can some one please take a look?
