What does action="/Resources" mean to JSP/Servlet?

What does action ="/Resources" mean in <form ... action="/Resources"> for JSP/Servlet?

In a JSP/Servlet side it could mean anything since any URL can be aliased to a givn resource, it could be translated by the server as resource.html, resource.jsp, another.jsp, and Servlet/ResourceServlet or even an image although these do not make that much sense.

Remember that the web.xml file allows you to define custom translations between a URL and what resource ultimately gets returned.
