Re: How to configure a custom page for JSP 404 errors?

[Ryan Lubke <Ry...@Sun.COM>]

Hi Pierce,

 From what I've been able to gather, you should be able to set
the error page using the <error-page> directive within the
deployment descriptor for a web app (web.xml).

<error-page>
    <error-code>404</error-code>
    <location>/error.jsp</location>
</error-page>

Looking through the bug database, there was an open issue
regarding the use of static html pages within the <location>
tag.  I'm uncertain at this time what release it's actually fixed
in, but if you try it and get a stacktrace, then I guess you know :)

The bug report can be found here:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=291

I did find this information in the archives.  
Try looking at the results of the following search:
http://mikal.org/interests/java/tomcat/archive/search?search=error+page+custom+404

I'm sure those who are more experiences could expand/correct on this 
information.
Hope this helps.
