Tomcat 7 is a Servlet 3.0 compatible container. Since Servlet 3.0, the servlets can be configured by @WebServlet annotation on the class without the need for a web.xml configuration entry. Look closer at the servlet class you just created, there's a @WebServlet annotation on it containing all information you specified in New Servlet wizard.

Effectively, this new way of configuring servlets

public class HelloServlet extends HttpServlet {}

does exactly the same as this legacy way of configuring servlets


If you still want Eclipse to create a web.xml entry for some reason, then you should change the Dynamic Web Module version back from 3.0 to 2.5 in Project Facets section of project's properties.
