Error pages do not show in JSF (Woodstock) app ...

[tonyweb]

Hi guys,
you can help me for sure.

I know it's a very popular question but I've never found a working solution (for my case).
I'm trying to show custom error pages for any kind of errors in my App ... but <error-page> configuration is ignored completely.

I'm using version 4.2 of woodstock components and NetBeans 6.1

This is my web.xml

As error-location I tried to put both an html, jsp or the exception handler servlet ... but none of them work :(

Coull you, please, help me ?
I need to use custom error page under jboss 4.2.

Thanks in advance

Regards,
Tony

P.S. Sorry for my bad english ;)

I have worked around by implementin a delegate pattern around the
standard JSF servlet, the best way I have found is with your own custom
servlet which you map to the standard servlet's previous url mapping
(say "*.jsf"); from that custom servlet you use exception handling
around a request dispatcher to the standard jsf servlet's new url
mapping (say "/TheJSFServlet/").

This complicates other issues as well but I've found it to be a working
solution for application exceptions.

Thank you for your quick and detailed answer.
I thought I could preserve declarative error handling ...
