Redirect from Exception Page (with Tomcat) in 5.1

[Moritz Gmelin]

Hi,

I'd like to have all Exception of my Application handled by its  
special ExceptionReport in the way that on the production system the  
ExceptionReport directly redirects the user to the start page.
This works well using Jetty as AppServer and checking for the error  
reason in beginRender and then sending a redirect.
Using Tomcat this fails and brings a Tomcat 500 error message
java.lang.RuntimeException: Page ExceptionReport did not generate any  
markup when rendered. This could be because its template file could  
not be located, or because a render phase method in the page prevented  
rendering.
The Error did not appear in T5.0.18.

So how can I realize such a redirect from the ExceptionReport page  
(which does not get through onActivate) using T5.1 and Tomcat?

Thanks

Moritz
