[jboss-user] [JBoss Seam] - How can I get jsf error pages to work similar to the blog sa

[Basel]

In my case I get "Exception Processing ErrorPage" when I try to access a jsf page that does not exist such as doe.jsf.

According to the following post on one of the mailing lists, having jsf/xhtml to handle error pages is not possible.
http://mail-archives.apache.org/mod_mbox/myfaces-users/200606.mbox/%3Cbc36a6210606241518w1b3879advfa85c6b1955a911a@mail.gmail.com%3E

However, this does not happen with the blog sample application. Also, the error page gets rendered without exceptions when I access a non-jsf page that does not exist such as asdoe.jsp, doe.other and doe.js. What could be the problem?
