exception action

[denis.diggin]

The exception handling in pages.xml is excellent

<exception class="java.lang.Throwable">
 <redirect>
 <message severity="warn">#{m.exception_general}</message>
 </redirect>
</exception>

Is there any way I can extend this "catch all" handler to execute an action e.g. e-mail an administrator?

You could redirect to a page with a page action.

Note that pages defined in pages.xml don't have to be real pages, you can use the render element inside a page element to render something else than the name specified.

Works, thanks.

<!-- Catch all exception handler -->
<exception class="java.lang.Throwable">
 <redirect view-id="/notify.xhtml">
 <message severity="warn">#{m.exception_general}</message>
 </redirect>
</exception>

<!-- notify the administrator that an exception has occurred -->
<page view-id="/notify.xhtml" action="#{exceptionNotificationService.send}">
 <navigation>
 <redirect view-id="/error.xhtml" />
 </navigation>
</page>

Use Contexts.getConversationContext().get("org.jboss.seam.handledException") to get the exception in ExceptionNotificationService.send()
