I've been tasked with converting an application which was developed by myself in the Waffle Framework using PicoContainer as a DI mechanism into our new "stack" which is to use Struts2 as a framework with Guice as the DI mechanism. Does anyone out there have any helpful pointers as to how to do this with minimal pain and at the same time getting the best out of both the new framework and DI mechanism? Many thanks in advance.
