spring exception

I am following this tutorial http://static.springsource.org/docs/Spring-MVC-step-by-step/part4.html to try and learn Spring.

Everything worked fine but when i got to part4 and made the changes at section 4.3 i get a runtime exception

        SEVERE: Context initialization failed

I dont think its an issue with missing jar files or classpath issues because it works fine without the bean properties specified in the xml file. I am not sure why this is happening so any help will be appreciated.

You are probably missing the org.springframework.web.servlet jar if your're using spring 3.0, or the spring-webmvc jar (should be in \dist\modules\ in the spring 2.5 distribution) if you're using 2.5
