I didn't try for the 500 error. Only 404 is handled "nativly" in OpenCms for
sure, for reasons of the static export. IIRC for all other error codes your
must add something into web.xml.

So for a XXX handler, you should add

    <error-page>
      <error-code>XXX</error-code>
      <location>/opencms/system/handler/handleXXX.html</location>
    </error-page>

Not sure about what's available in the JSP and what not. Try accessing the
Java servlet / JSP standard objects for the error handler (see above),
probably located in the request context. These should provide you with all
information required. Didn't try that so far.

It's not unlikley we will add some handlers / pages by default until the 6.0
final is ready. 

Best Regards,
Alex.
