Unable to instantiate Action, signupFormAction, defined for 'signupForm' in namespace '/'signupFormAction. ClassNotFoundException: signupFormAction

Been trying to setup a Struts2 + Sprint + Hibernate basic framework and was working on creating a sample application. Everything configured and the stack doesnt through any error/exception while starting tomcat. Even when I run the action it doesnt throw any Exception, but on the browser it throws the following stack

I made a trivial mistake which costed me hours of pain. Silly me the problem was that my class name in struts.xml and id in register.xml were not matching and hence the issue.
