What I did before the integrated version was to import one of the example .war files that came with Struts into WSAD. I stripped out everything about the app to make a skeleton Struts/Tiles app and packaged _that_ as a war file I could import in, rename, and go to work with. This means I can skip the wizards and get all the defaults that I use for my projects at the same time.
