Tuscany Web Application based Integration with Geronimo

Package the Tuscany application as a WAR with all the application jars/classes and Tuscany jars (including the dependencies) in the WEB-INF/lib folder. Configure the deployment plan to enable "inverse-classloading" so that the Tuscany jars and dependencies are loaded first by the web app classloader.
