First off, let me start by saying that I am new here and I am new to Spring, so forgive me for asking remedial questions. I have been going through the Spring Framework Tutorial that is provided by spring source on this site (http://static.springsource.org/docs/Spring-MVC-step-by-step/index.html). In going through this tutorial, I have come across some odd behavior regarding servlet mapping (or so I think). What is happening is that I am trying to map a "hello.htm" url to reference a specific class which then pulls the view from a hello.jsp file. Well, this is not working. When I try to look up http://localhost:8080/springapp/hello.htm Tomcat says the resource could not be found. When I try to pull up http://localhost:8080/springapp/hello.jsp, the page views as it should. However, in the tutorial, it specifically states that you are supposed to be able to view it through looking up the hello.htm URL. I have looked over and over all of the files in the project and cannot figure out what could be going on. Please help. I believe that all of the relevant config files are listed below...
