adidar,
you will have to explain in a little more detail what you want… let me explain how I understood you:
1) You have 2 projects, A and B
2) You want to setup A to be a dependency of B (e.g. maybe a library or something)
3) When you deploy B to Tomcat, you want it to deploy A as well?
Is this accurate? If so, then this is a very common enhancement request to the deployment tool that will be added in the upcomming release of ME. If this wasn’t what you were asking, please describe the kind of behavior you wished ME had.
