## ClassNotFoundException in a simple spring application

Hello,
I am trying to write a very small web-application using spring framework (MVC). I am using tomcat and eclipse.

When i run the application i get the following error:

Caused by: java.lang.ClassNotFoundException: controller.WelcomeController

But in fact WelcomeController.java exists under controller package, and also i can see that the class file WelcomeController.class exists under WEB-INF/classes/controller/ directory.

What might be the reason of the problem?

As far as i know eclipse is dealing with the classpath by itself, how can i check the classpath used by eclipse?
