Actually, that's another way to go, a Filter. However, I was actually referring to the fact that Struts 1.3 uses a composable request processor based around the CoR pattern. With that, you can modify the series of steps (Commands) that get executed with each request. This is within the context of ActionServlet though, so you get access to all the Struts internals this way. It soundslike adding a Command or two to the processing chain would allow you to do what you need. But, if you wanted to support pre-1.3 as well (and I would think you would since 1.3 isn't officially out yet) then you'd have to go the custom RP route (although, there would be nothing to stop you from simply executing a chain from the RP, so at least your Commands could theoretically be identical for both versions).
Question: is there any way to do what you require within an Action? I just *very* briefly skimmed over the doc you referenced here, and it seems like you might be able to get away with it. If you have a specific Action that does what your servlet does, invokes the referenced class method and all, would that suffice? That way you could avoid all the Struts customization entirely. -- Frank W.
