spring MVC helloworld application shows CannotLoadBeanClassException

I am a novice to spring MVC.I am follwoing a tutorial from the bellow link: Spring Hello World

While running the application on tomcat server it shows following exception,I guess it is related to the controller class file path,but can't solve it:

javax.servlet.ServletException: Servlet.init() for servlet SpringMVCTutorial threw exception

Looks like you class file corresponding to java.com.springmvctutorial.web.controller.HelloWorldController is not under classpath.

So two things to check here ;-

1)Class file for HelloWorldController created or not.

2)If yes, folder containing i.e java.com.springmvctutorial.web.controller.HelloWorldController should be under classpath

Ideally package name should start with com.springmvctutorial.. not with java.com.. as per java convention

You put wrong class path at SpringMVCTutorial-servlet.xml. Use following path

<bean name="/helloworld.htm"
     class="com.springmvctutorial.web.controller.HelloWorldController"/>
