Jaas Login redirects you to error page only when authentication fails. When you get a authorization failure, you would be getting a 403 response status code. Try to configure your web.xml & see if on receiving 403 whether you can redireect to your desired page.
Thanks for help, worked fine by adding
<error-page> <error-code>403</error-code> <location>/sorry.html</location> </error-page>
