Can't get the Seam Exception Handling feature to work.

[whuang]

I try to setup Seam to handle all JSF exceptions and redirect to a generic error page, but still when exceptions occur, it is not redirecting in to my generic error page.

Based on the Seam doc, I config my exceptions.xml in WEB-INF

<!DOCTYPE exceptions PUBLIC
 "-//JBoss/Seam Exceptions Configuration DTD 1.1//EN"
 "http://jboss.com/products/seam/exceptions-1.1.dtd">

<exceptions>
 <exception>
 <redirect view-id="/error/error.xhtml">Unexpected failure</redirect>
 <end-conversation/>
 </exception>

</exceptions>

and on web.xml

<!-- =================================================================== -->
 <!-- Seam -->
 <!-- =================================================================== -->
 <listener>
 <listener-class>org.jboss.seam.servlet.SeamListener</listener-class>
 </listener>

 <!-- Propagate conversations across redirects -->
 <filter>
 <filter-name>Seam Redirect Filter</filter-name>
 <filter-class>org.jboss.seam.servlet.SeamRedirectFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>Seam Redirect Filter</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 </filter-mapping>

 <!-- Needed to ensure safe tx cleanup when using Seam-managed sessions/persistence contexts -->
 <filter>
 <filter-name>Seam Exception Filter</filter-name>
 <filter-class>org.jboss.seam.servlet.SeamExceptionFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>Seam Exception Filter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

Where is the error being generated?

[whuang]

I have seen it on during the Apply Request Values or Update Model life-cycle when I purposely map a invalid method binding... But I've also experience it during other life-cycles.

[whuang]

Does seam exception handling only handle in invoke application phase? or is suppose to handle exceptions in ALL phases?

BTW, my environment is MyFaces 1.1.3, Facelets 1.1.11, Seam 1.1.0, A4J 1.0.2, weblogic.. Everythings else works great including seam(mainly use for wizard conversation)

Thanks,
Bill

I am seeing this on my log


2007-01-22 10:26:06,636 INFO org.jboss.seam.core.Exceptions - reading exceptions.xml

2007-01-22 10:26:06,667 ERROR org.jboss.seam.core.Exceptions - redirecting to debug page


Looks like I am in the right path, but I don't remember requiring to create a debug page and how come it does not redirect to my error page..

Thanks,
Bill

I am having the same problem, I'm eager to see the solution to this.

one year later - and the same problem, now with seam 2.0.0.
is there "already" a solution to this?

note: if I set a class to the exception like "" it works! but using just "" without specifying a class, it does not redirect to desired page.

oh sorry, it lost my xml tags:

for the first "", replace

<exception class="javax.servlet.ServletException">

for the second one, think of

<exception>
