Hi Joe! When I posted the initial mail I didn't understand well how ExceptionHandler works, but now I think already do, I'll tell you how I figure it out and if perhaps I'm wrong please correct me, ok?
- We can have as many exceptionHandler as we need, and we configure who will be or ExceptionHandler indicatting in the struts-cfg.xml as well the Exception type to be handled; - The default ExceptionHandler receives this request and looks for the action scope and then stores ActionErrors objects; - In the JSP side the <html:errors /> taglib looks in the pageContext the ActionErros, read the ApplicationResources and mount the output as defined in the taglib(but it allways want a key and the ApplicationResources); I had a specific need, and didn't want to work the way described bellow, I wanted an *Exception* to be in the pageContext not an *ActionErrors* cause what is printed is got from an XML file. I created my SisprevException with cause, action and code attributes, I needed this attributes to be printed out to user. So I created my own ExceptionHandler and handled my exceptions according to my needs, put my SisprevException in the request/session. I also create my own taglib to handle this SisprevException in the request/session and print out its attributes values. The question: did I reinvented the wheel? is there already a way to do what I did without the need to write what I wrote? thanks * Leandro Dorilêo Desenvolvedor Java ÁBACO Tecnologia de Informação Ltda Qualidade: Um Compromisso de todos!

One common error which might be related to what you're seeing is when the ExceptionHandler is invoked during Tiles evaluation; in this case, the response is usually already committed, so the ExceptionHandler can't forward to the configured JSP. If you aren't using Tiles, then you probably have a different kind of misconfiguration. I'd suggest posting some of your config info to this list to see if anyone can help you. I have been using a local ExceptionHandler which tests to see if the response is committed and uses "include" instead of "forward" when it is; this works pretty well if your error page would look OK inlined in a subregion of a page as well as in the main page body. I'm hoping to refine this a little and introduce some kind of support for it in Struts 1.3 joe -- Joe Germuska [EMAIL PROTECTED] http://blog.germuska.com "Narrow minds are weapons made for mass destruction" -The Ex
