Error 404: javax.servlet.UnavailableException: SRVE0203E Error in Spring Application / Rational Application Developer 9 / WAS 8.5

I am currently attempting to run a very simple Spring application in RAD 9, on the local Websphere 8.5 Liberty profile. The code is from this site: http://ift.tt/1yJE2ow

I'm using Maven. Here's my pom.xml:

There is a very simple view in WEB-INF/views. The controller is defined in the Java classes The Spring DispatcherServlet is configured in web.xml as described in the tutorial mentioned above:

HelloWorldController.java

package com.programcreek.helloworld.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {
    String message = "Welcome to Spring MVC!";
    public HelloWorldController(){
        int i = 5;
    }

    @RequestMapping("/hello")
    public ModelAndView showMessage(
            @RequestParam(value = "name", required = false, defaultValue = "World") String name) {
        System.out.println("in controller");

        ModelAndView mv = new ModelAndView("helloworld");
        mv.addObject("message", message);
        mv.addObject("name", name);
        return mv;
    }
}

I have arrived at a point where the application will run, and I can visit a simple index.jsp. However, any other route leads to the error below.

I have found many questions and posts dealing with this particular error, but no real help diagnosing or resolving it. I have reviewed all the dependencies of the DispatcherServlet and, as far as I can tell, they're all present in the jar file that is deployed. Any guidance would be greatly appreciated!! TIA!

Error 404: javax.servlet.UnavailableException: SRVE0203E: Servlet [DispatcherServlet]: org.springframework.web.servlet.DispatcherServlet was found, but is missing another required class. SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server. SRVE0187E: Check your class path to ensure that all classes required by the servlet are present.SRVE0210I: This problem can be debugged by recompiling the servlet using only the classes in the application's runtime class path SRVE0234I: Application class path=[C:\Program Files\IBM\WebSphere\AppServer\java\lib;C:\Program Files\IBM\WebSphere\AppServer\java\lib\dt.jar;C:\Program
