I just don't (yet) see how or where you can set an action override. Am I supposed to add a chain called "servlet-complete-preprocess" and put my own code in to figure out what action is being invoked and somehow which chain I want to call next? I guess I was expecting something in the struts-config.xml via a set-property or something that easy to suggest where or how to chain it. I suppose this means I need more reading. Can you suggest any links?
David:
There isn't a lot of existing doc for struts-chain. This will be the major task for making it the base request processor for a future version of Struts. Discussions like this will help us understand how to explain it to people!
I'm not sure I understand exactly what you're trying to achieve. Do you have a case where you have significant control logic which benefits from being broken out into "sub-chains"? It would be interesting to hear some more specifics about how people are thinking of applying the chain model to Struts.
In any case, it would probably be a lot of redundant work to have parallel chains that duplicate most of the logic flow in "servlet-standard", so selecting an entire chain in "servlet-complete-preprocess" may be the "wrong" place. Depends on how different your processes are.
In many cases, you could just add a few commands into servlet-standard which inspect the request state contained in the chain Context and which optionally perform behavior, rather than duplicating the entire "servlet-standard" chain.
Of course, you could also replicate the "set default, then identify sub-chain" type logic which happens in servlet-complete to configure a bit of branching within servlet-standard, minimizing duplication, but still providing some flexibility.
It may be because I'm conditioned to solving problems within the standard Struts request processing sequence-of-events, but for my first struts-chain based app, I simply added a few commands in the main line, rather than configuring any kind of branching.
