Thanks for the reply, at least I know someone else has gotten it to work at
this point.
Sorry for the lack of information. I am on a deadline and trying to do too
many things at once. I've included all the important things I can think of
below.
Tomcat Version: 5.5.17
Error type: I am seeing a 503 http error code being returned, but I want to
be able to catch exception classes rather than specific error codes.
I have tried
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/yourErrorPage.jsp</location>
</error-page>
and
<error-page>
<error-code>503</exception-type>
<location>/yourErrorPage.jsp</location>
</error-page>
in both my application web.xml, and in the tomcat web.xml (with the default
servlet) with no success. I still get a generic tomcat error page showing a
stack trace.
How is the error-page location related to my app? I assumed that the root
of the location corresponded to the root of my app, but maybe I am
mistaken. Would tomcat still use the default error page if it can't find
the error page, or would it give me a different error? Oh, and can the
error pages be static html (mine are, perhaps that is the problem)?
As for the application, the servlet init method sets up all the servlet
dependencies through spring config. When there is a problem with the config
file an exception is thrown and I see the error page.
Thanks for any help,
Adam Parker
