A simple test, is little program called "HitServlet", the code could be something like this .
You might need to compile it, or get the class file here. In Your Tomcat/webapps, You create a library called "hitservlet". Under this You further create some other libray so You end up with a structure like this:

Tomcat/webapps/hitservlet/images/tomcat.gif
Tomcat/webapps/hitservlet/META-INF/context.xml
Tomcat/webapps/hitservlet/WEB-INF/classes/HitServlet.class
Tomcat/webapps/hitservlet/WEB-INF/lib/
Tomcat/webapps/hitservlet/WEB-INF/web.xml
Tomcat/webapps/hitservlet/index.html

And now to the test. In order to test it You have to restart Apache and Tomcat.
Do this:
Start the browser and put in the url:
"localhost/hitservlet"
and next
"localhost/hitservlet/HitServlet"
