How to print list in a jsp?

For some reason Apache Tomcat 7.0 doesn't run my main servlet (PlaceListServlet) that should list a bunch of database items on place-list.jsp page. I keep getting 404 everywhere, and Eclipse doesn't report any errors in the source. What seems to be the problem?

• Answer:

  If you do not configure the servlet and servlet mapping in web.xml the request will not reach your servlet and you will get 404.
