Spring MVC Problem

Hi,

I'm new to Spring So I'm develop some Spring MVC application. But I got 404 error. Here is the code.

HelloController.java

hello.jsp

web.xml

springapp-servlet.xml

ref : http://static.springsource.org/docs/Spring-MVC-step-by-step/part1.html

When I'm going to run on tomcat server I got the following Exception

org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [springapp.web.HelloController] for bean with name '/hello.htm' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]; nested exception is java.lang.ClassNotFoundException: springapp.web.HelloController

What is the wrong with this code ? Please give a help to run this.

This exception clearly tells you that, spring can't find the controller class.. Are you sure, your controller class is compiled..
Try rebuilding the application.

Just an added note. If you are learning Spring and Spring MVC here, I recommend using the latest version of Spring, which deprecates the Controller interfaces for the better @MVC approach.
