It is probably possible to do this, but depending on what parts of WW2 you want to leverage, it's also probably working too hard. To me, the coolest part of WW2 (and the part of the merger will help Struts 1.x users the most) is the way that XWork is used inside to build up an interceptor chain that customizes the behavior of each request. This can be done (if I'm understanding WWiA correctly :-) either locally or globally. It turns out that you can do that on top of JSF as it is today, pretty easily. * For global interceptors, use a servlet filter similar to what Shale already does with a global Commons Chain for pre-process and post-process behaviors. (There might be some issues I haven't explored yet because a filter separates the pre and post processing.) * For local interceptors, JSF lets you override the "default action listener" ... the gadget that actually calls your action's execution method when a submit happens. It's pretty straightforward to implement a custom listener that looks up an appropriate XWork definition and wraps the call to the action. It's much easier to use extension points built in to the architecture than replace the whole implementation :-). Side note -- you know the way that WW2 lets you combine the Struts notions of Action and ActionForm into a single class? JSF does that already too :-). -- > James Mitchell Craig
