Tomcat7 deploy Fail: org.apache.catalina.LifecycleException: Failed to start component / w org.springframework.web.servlet.DispatcherServlet

I have a very simple web.xml example written below:

The problem is ... If I delete the org.springframework.web.servlet.DispatcherServlet section, I can successfully deploy my project to Tomcat7 as a simple JSP servlet application. However, as soon as I use Spring MVC, my deployment will be FAIL - The exception org.apache.catalina.LifecycleException is thrown: Failed to start component [StandardEngine [Catalina] .StandardHost [localhost] .StandardContext [/ WebMVCProj2]]

How can I fix this error?

I am adding a Spring MVC dependency from the Enterprise Bundle repository (EBR). I also use the Eclipse Dynamic Web Module 3.0, which should support Tomcat7. My jre is 1.6.x 64 bit used by Tomcat and my project. I also use the web deployment build in Eclipse.

Here is my complete exception:

You must have applicationContext.xml in the web-inf folder or you need to define contextConfigLocation in your web.xml

 <!-- Spring Context --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/application-contexts/*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

It would be more useful if you could post an exception trace.
