Servlet Mapping w/ Error Page
I have a servlet mapping for a page named
/403.html
I can invoke that URL and get a page as expected.
In my deployment descriptor, I have an error mapping:
<error-page>
<error-code>403</error-code>
<location>/403.html</location>
</error-page>
in my code I have
if (someCondition) {
res.sendError(HttpServletResponse.SC_FORBIDDEN);
return;
}
When this code is hit, my custom page is not displayed. I get a blank
page. No error is thrown by tomcat.
If I change the error-page entry to reference a static HTML page, the
page is displayed as expected.
This looks like a bug to me, but I wanted to run it past tomcat-user
and see what other people think.

Hi, George-
One thing to look out for is that <location> is "relative to the root of
the web application". To me, this means that the error page must exist
in every context in which it is declared.

Sorry, I had the best of intentions here. I dl'd the 6.0 for testing.
6.0.35

I looked at this a little more. It looks like the response may have been
committed before calling HttpServletResponse.sendError(). Once I
re-structured the code to not commit the response, it started working.

1. Tomcat version=?
Overall it looks like a bug. But if you submit it I expect you to
provide a simple sample webapp that reproduces it on 7.0.23.
