RequestProcessor is the class to which the ActionServlet delegates the bulk of its work processing a request (ie: populate form, call Action execute, etc...).
Struts makes it easy to replace the standard RequestProcessor with your own implementation. Normally this would extends org.apache.struts.action.RequestProcessor and selectively override the methods that it is interested in modifying the behaviour of. You specify which RequestProcessor to use in your struts-config (there can be only one...) Be aware that some extensions (I think Tiles is one of them) already override it - so you would need to override their version instead of the base one. The node of interest in struts-config is the "controller" node. ie: <controller processorClass="com.unist.plot.to.subvert.struts.EvilRequestProcessor" locale="true" contentType="text/html; charset=UTF-8" nocache="true" maxFileSize="128M" bufferSize="8192" debug="5" /> The RequestProcessor has enormous power over the struts request processing lifecycle and hence can be *very* useful to override to provide custom processing for certain things... It was introduced in struts 1.1 - in struts 1.0 the functionality for it was part of the ActionServlet class itself, so if your still on 1.0.2 you need to override that instead. Check the docs for details: http://jakarta.apache.org/struts/api/index.html Though in this case the best documentation is the source code itself :-) -----Original Message----- From: Renato Romano [mailto:[EMAIL PROTECTED] Sent: Tuesday, 25 March 2003 22:17 To: [EMAIL PROTECTED]; 'Struts Users Mailing List' Subject: RE: ActionForm reset method Ok. That's all clear but one thing: what is RequestProcessor? ____________________________________ Renato Romano Sistemi e Telematica S.p.A.

In my app I needed to switch it off for certain specific actions so I created my own action mapping class with a noReset parameter , and overrode RequestProcessor to check for that. Needless to say I later needed something a little more dynamic - so I also added the ability to control it with a certain query parameter which I checked for in my base ActionForm class which all my ActionForms extend. I then renamed all my ActionForms reset methods doReset() and called that from the base only if the parameter was set. -at which point I realised that I should simply have added a check for that parameter in the RequestProcessor (thats lack of sleep for you!). <btw> While adding this functionality to RequestProcessor is quite simple, you will note that it isnt there already as a feature (likewise for conditional population). This is because the struts developers considered it likely to cause people more problems than ... ummm ... whats a good word ... 'unproblems', I believe they did think it okay for people to do it themselves as if they know how they probably know what their doing and wont get into strife... :-) <btw> -----Original Message----- From: Renato Romano [mailto:[EMAIL PROTECTED] Sent: Tuesday, 25 March 2003 21:40 To: 'Struts Users Mailing List' Subject: ActionForm reset method Is there any way to control the ActionForm reset method invocation ? I need to call it "manually", only in some cases. It seems the only alternative is to define a myReset method ... Thanks ____________________________________ Renato Romano Sistemi e Telematica S.p.A.
