[Building Sakai] custom 403 and 404 pages

[Matthew Jones]

Also, if you're running apache (or something) in front of your tomcat with
mod_jk or ajp [1], I think you have to put these in the VirtualHost in
there. Then they can point to anywhere that's under the defined DocumentRoot
or a URL.[2]. Actually seems a bit easier.

        ErrorDocument 503 /ROOT/error-pages/503.html
        ErrorDocument 404 /ROOT/error-pages/404.html
        ErrorDocument 403 /ROOT/error-pages/403.html
