i placed the spring-webmvc.jar in the classpath which i think contains org.springframework.web.servlet.DispatcherServlet and other combinations of various libraries but that hasn't solved it. any suggestions? also is there any place to pick up all the current dependencies for an mvc application?

thanks

Use spring.jar may be there are missing dependencies which is actually causing this problem


I just want to know is there any body call my bean's Getter and Setter methods with "Please" in front - My favorite quip from Bugzilla
