Holger,
I implemented both dopost and doget. Both write contain a write to log. Neither
seem to execute.

Hello,
the path in the tomcat manager app brings you to http://localhost/WEBAPP/
or http://localhost/WEBAPP/index.html via HTTP GET. Is your servlet
configured to reply to that url? This is normally done in web.xml with
the <url-pattern> Element.
Moreover: as you seem to be writing a doPost() Method. You will
get a 405 when using HTTP GET via the link at best.
