I think you should be able to avoid geronimo plans for each module.

You need to

1. make sure that the name specified in the annotations or dd resource- 
ref is the same as the datasource name you specify when you deploy the  
connection pool.
2. make the connection pool "visible" to your application by adding  
its id as a dependency to the geronimo plan for your application.

This should be enough to make the auto-map work.

hope this helps
