I am working on a web app that I'm running on Tomcat 6.0.18, and I am using Apache 2 as a reverse proxy. This works fine. I'm also trying to get Apache to display error pages when, for example, I've shutdown Tomcat for redeployment etc. However, the ErrorDocument directive in my httpd.conf doesn't seem to work at all for local files. I've tried external urls and strings and both of these cases work fine. But the below does not work:
ErrorDocument 403 /Oops.html
ErrorDocument 404 /Oops.html
ErrorDocument 502 /Oops.html
ErrorDocument 503 /Oops.html
The Oops.html file is in my htdocs folder. Here is some log output from httpd when I try accessing app when Tomcat is not running but httpd is:
==> access_log <==
localhost - - [21/Nov/2010:12:23:36 -0800] "GET /home HTTP/1.1" 503 -

Note that I'm not using an .htaccess file. It seems that there is some problem with the settings related to htdocs folder. Below are some bits from my httpd.conf file that has to do with the htdocs foler. I'm new to working with Apache so I'm not sure how relevant this is or if I should post more.
<Directory "/usr/local/apache2/htdocs">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Any help much appreciated!
EDIT:
When Tomcat is running I see these lines in the error log:
[Sun Nov 21 13:30:11 2010] [error] [client ::1] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

Something isn't configured correctly but I have no I what or where. Thanks for the responses so far, but still stumped.
