really dumb question: tomcat + apache

I'm trying to merely run the sample application given with the Tomcat documentation. I'm using tomcat-apache.conf. Merely using the ant tool like to doc tells me... Why do servlets only work when I address it as: http://localhost:8080/myapp/hello but it doesn't work when I put:

Servlets wont run

When I run Tomcat with Apache, I can't get the sample Tomcat to execute the servlet (non jsp). I'm guessing its a config issue but I'm merely experimenting. Does anybody have any suggestions?
