Still no answers so I will add more information: 1. I'm using jboss 5.0.1 and 5.1 and see the same problem 2. I'm throwing RuntimeException from the application 3. even when using exception-type instead of error-type and setting it to Exception I still can not reach to my custom error page. Again, any ideas??? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4258057#...
