Re[2]: If several JSPs share the same action mapping...?
Sorry James, I don't think I described the situation to well and I'm sure there probably is a better way to handle this... Easiest way is an extreme example.. What if you had 4 different JSPs that captured the same information in a form YET everything else on the page was radically different. Upon submission, though, you want to forward all the pages to the same Action and even possibly forward all of them to the same results page. The problem(I think) is you also want to validate the form information. I'm wondering how you would get the validation to know to return back to the correct JSP page if there were validation errors? I thought you needed to provide the input=yourJsp.jsp so that it knew were to go back to, but if all 4 jsps shared this action mapping what would you put in the input=? section? (maybe I'm totally wrong and the validation doesn't need that but I thought it did).

How to do you deal with the input=? parameter when setting up an action mapping that different JSPs will share? I thought this input declaration was so if you are using validation it knows which page to return to with the validation errors. How is this accomplished when you have different JSPs that could share this action mapping but also need to be validated and thus I think also require the input field to be supplied?

Sorry if I was confusing, yes I meant JSPs sharing an action-mapping. I was trying to avoid having to write the same action-mapping over again for a few jsp's that are very similar and will end up fowarding to the same page after validation. The similar forms on each page will need to be validated though and I was just trying to find a good way to accomplish this but ran into a snag because the input has to be defined in the action-mapping that they would all share, so how would the validation know which page to return to if there were errors? TH Of course, action-mappings can also share JSPs, and so forth. There are TH no 1:1's here. TH -T.

RE: Re[2]: If several JSPs share the same action mapping...?
Rick, if you have multiple JSPs all using the same action and need to determine where to send the user upon a validation error, why not just have several action mappings and explicitely define the appropriate input path for each one. That's what the action mappings are for. I don't think it is necessarily bad to have a bunch of action mappings. IMHO, I would rather have multiple action mappings than a code kludge. My advice would be to use the framework. You can always use a tool to manage your struts-config file. I do this very thing for my project. I have productized download screens that all use the same download action. If an error occurs, I need to send them back to the correct product download screen. Using multiple action mappings that all map to the same action but have different inputs defined has made this extremely easy. No kludge at all.
