I based mine on the existing struts2 plugin, and it's much more complicated :) There is a lot of code in there to ensure that an interceptor only gets created once (at least that is what I think it's doing). Is all that code unnecessary? I suppose I could test if it's an interceptor and use the singleton scope from guice, and that might solve the problem as well.
I guess based on your example that binding the classes isn't necessary either, we can just use the implicit bindings, which makes total sense once you see it. That was part of my biggest disconnect, was trying to bind all the struts2 classes when that wasn't necessary. Thanks again Dhanji! Brian On Jan 22, 11:51 pm, "Dhanji R.
