Dear all,
=20
I am trying to find out if there is an alternative way of telling Tomcat
not to send information to the client browser in a=20
case of an error (Stack trace, Root Cause ...) in the application rather
than by defining an error-page in web.xml.

Solution I already implemented in web.xml:
=20
<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/page_not_foung.jsp</location>
</error-page>
=20
<error-page>
    <error-code>500</error-code>
    <location>/page_not_foung.jsp</location>
</error-page>

The above solution works fine. But what I am trying to find out is - if
there is a way to tell Tomcat not to send=20
error messages and Version Information to the client browser with out
using the above mentioned error-page.
=20
Is this possible? If yes - I will be very thankful for any hint!
