Paul, If manager is in this install then when you view the manager page it is listed at the bottom.
If you are able to put the context.xml in the META-INF directory and it get deployed via that context then you are on TC5. If this is TC4 then that is part of your problem. It will deploy using the default context which will not give you the link to the resource. Look in your logs for the deploy actions and see if it is seeing the context.xml. While you are there also see if any error are showing up in the logs. Yeah, go ahead and post all your config file parts and the code snippet that calls the database.
