Re: TC 4.0 newbie - servlet app won't run (correction)
Correction, using POST results in a 405-Resource not allowed due to the HelloWorldExample servlet not implementing doPost(). Others do and work fine with POST. My apologies.

Re: TC 4.0 newbie - servlet app won't run (correction)
I will reply, Mark, in bits and drabs, as I try to figure out what you are missing and what you may have wrong. First, the servlets I referred to are not any different as servlets. They are not compiled JSP pages. The are regular old servlets. Compiled JSP page servlets are kept in tomcat/work/.

Re: TC 4.0 newbie - servlet app won't run (correction)
I have not looked at the webapps/examples except incidentally, Mark, so I am not sure how the HelloWorldExample servlet is accessed. How you access a servlet and where the servlet is are very important in these contexts. Inside and outside WEB-INF are very different, for example. Inside WEB-INF is dark to the outside world and must be accessed differently than outside WEB-INF. There must, as it were, be a portal. I still have not received answers from my last questions, which I need to go forward in my attempt to see what you may be doing. Certain answers to those questions could resolve everything.
