Are you familiar with my project Paul? If not, I'll briefly explain (otherwise, just skip to the third paragraph)...
It is a project that allows Actions to be exposed as Web Services with no changes to the existing code. All a developer has to do is add a plug-in, and optionally a new webservices-config.xml file, and the Actions can be called by SOAP clients without doing anything more. However, one of the things that is lacking in the current version is proper handling of form validation errors. I think essentially the request would die a horrible death at worst, and at best just return gibberish, because the errors are not handled in any way. I need to add that capability. To address your specific question, the input page is irrelevant in this situation because input did not come from that page. However, I want such a request to return a "real" error message, still as a valid SOAP-based response. As all the output is now generated by JSP templates, it makes sense to do the same to handle these validation errors. So, I therefore need a way to make the RequestProcessor (where all the things that make this work in the first place are done) forward to a JSP, regardless of what the input page attribute might say. Alternatively, a developer would have to add an extra mapping for every Action they want to expose as a service, but that is contrary to my "quick ,easy and transparent" goal that I've been following all along. -- Frank W.
