Ok, I must be doing something silly... I've deployed tomcat hundreds
of times, and never had something like this happen.
Just needed to test something simple on a new system.
Grabbed tomcat 7.0.26, unzipped it.
Configured it to run with my local java:

Is there a proper way to write an error page, so that it will work

There seems to be a bug or inconsistency in how tomcat handles the error page.
In Tomcat 6.0.20, if I define my error page like this in web.xml
On the page: http://tomcat.apache.org/tomcat-6.0-doc/jasper-howto.html

Then put your timer code into a new servlet that you add to your
