Exception handling with @HttpError not working

[susnet]

My Exception class:

@ApplicationException(rollback=true)
@HttpError (errorCode=HttpServletResponse.SC_NOT_FOUND)
public class PageNotFoundException extends Exception {


 /** Creates a new instance of PageNotFoundException */
 public PageNotFoundException () {
 super ("Page not found");
 }
}

In web.xml

<error-page>
 <error-code>404</error-code>
 <location>/pages/error/error404.xhtml</location>
 </error-page>

Instead I get a 500 error.

Why is this not working? Any ideas?

I use Seam 1.2.1 on JBoss 4.0.5. I don't have any other problems with my application.

In web.xml I also have:

<filter>
 <filter-name>Seam Filter</filter-name>
 <filter-class>org.jboss.seam.web.SeamFilter</filter-class>
 </filter>

 <filter-mapping>
 <filter-name>Seam Filter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

When I deploy my app i can read in the log:

INFO [Lifecycle] starting up: org.jboss.seam.servlet.exceptionFilter

If I put

 <exception>
 <end-conversation/>
 <redirect view-id="/pages/error/error404.xhtml">
 <message>Unexpected Failure. </message>
 </redirect>
 </exception>

in pages.xml, it does not work either. The exception just falls through and an ugly error message will be shown (if i'm not adding an errorpage for 500 in web.xml).

I have <core:init debug="false" .. in my components.xml.

I have searched the internet, read in this forum, read the seam manual 1.2.1 and I've spent several nights testing everything i can come up with but I can't get this to work. Please help!

The problem was solved by adding

<context-param>
 <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
 <param-value>client</param-value>
 </context-param>

to web.xml.

No, forget what i wrote in my last post.
The problem was that i'm using Tuckey URLRewrite. Then the Seam filter must come BEFORE the URLRewriteFilter in web.xml.

Like this:

<filter>
 <filter-name>Seam Filter</filter-name>
 <filter-class>org.jboss.seam.web.SeamFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>Seam Filter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

 <filter>
 <filter-name>UrlRewriteFilter</filter-name>
 <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
 <init-param>
 <param-name>confReloadCheckInterval</param-name>
 <param-value>0</param-value>
 </init-param>
 <init-param>
 <param-name>logLevel</param-name>
 <param-value>WARN</param-value>
 </init-param>
 </filter>
 <filter-mapping>
 <filter-name>UrlRewriteFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
