Re: MyFaces failing to show JSF error page (bug)

Wed, 23 Aug 2006 04:52:36 -0700

If your error page contains JSF then the location should use the .jsf extension (or whatever url mapping the FacesServlet is configured to use): 

<error-page>
   <error-code>404</error-code>
   <location>/resources/pages/fileNotFound.jsf</location>
</error-page>

etc.

Hi, Browsing through earlier posts, it appears that if you specify an error-page in the web.xml <http://web.xml> AND IF this page contains jsf tags (pure jsp & html goes aparently fine), MyFaces throws an Exception. I've experienced this myself too. Is there a remedy/fix planned? 
The code:

In my web.xml <http://web.xml> I have:
/<!-- For Error Handling: for both general java exceptions and the Page Not Found case: -->/ 
/<error-page> /
/<error-code>404</error-code> /
/<location>/resources/pages/fileNotFound.jsp</location> /
/</error-page> /
/<error-page> /
/<exception-type>java.lang.Exception</exception-type> /
/<location>/resources/pages/generalJavaErrorPage.jsp</location> /
/</error-page>/


E.g. the fileNotFound page features:

/<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>/
/<jsp:root / /xmlns:jsp="http://java.sun.com/JSP/Page"; version="2.0"/
