Tomcat not loading Dispatcher Servlet (ClassNotFoundException) - spring

Question

I have tried to search and make changes as per answers for above question, but not working. I am not using any build tool.
All the jar files jstl1.2, common loggings 1.1.3 , and Spring 3.2.3 jars are in WebContent/WEB-INF/lib
index.jsp is welcome file is shown properly in Eclipse browser, but when I click on hyperlink for controller, give 404 Requested resource not available. From the log seems tomcat is not loading dispatcher servlet
I tried restarting/clean and publish tomcat,
using tomcat 7, jre7, eclipse kepller 4.0, with java ee 2.0
Appreciate your help

Answer 1

Based on the stack trace you are missing spring-webmvc.jar which contains DispatcherServlet class. Try check your classpath again (WEB-INF/lib) to make sure that jar is there. Typically on a Spring MVC application you'll need these jars:
I also recommend you use dependency management tool (eg: Maven / ivy) otherwise it's too hard to manage the jars yourselves

Answer 2

Just add all needed jar files to WEB-INF/lib folder, then it works for me.
in this case only that DispatcherServlet class found
