Getting ClassNotFoundException while setting up Spring 4.0 Simple project Setup

Question

I'm setting up a simple project with Spring 4. I'm not using Maven. Instead I've simply added the Spring Dependencies by adding the Jars to the classpath. I'm using RAD 8.5 and Websphere 8.5 for this project.

When I am trying to start up the project, it is giving error: class java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

I've provided the following in the web.xml:

<servlet>
        <display-name>Controller</display-name>
        <servlet-name>Controller</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Controller</servlet-name>
        <url-pattern>*</url-pattern>
    </servlet-mapping>

My Controller-servlet.xml looks like:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
 xmlns:context="http://www.springframework.org/schema/context"  
 xmlns:p="http://www.springframework.org/schema/p"   
 xmlns:mvc="http://www.springframework.org/schema/mvc"   
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
 xsi:schemaLocation="http://www.springframework.org/schema/beans  
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
http://www.springframework.org/schema/context  
http://www.springframework.org/schema/context/spring-context-4.0.xsd  
http://www.springframework.org/schema/mvc  
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> 

    <context:component-scan base-package="com.spring4.controller" />
    <bean id="viewResolver"
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/view/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>  
</beans>

My Controller class looks like:

@Controller
public class HelloSpring4Controller {
    @RequestMapping("/hello")    
      public ModelAndView sayHello() {    
       String message = "Welcome to Spring 4.0 !!! ";    
       return new ModelAndView("welcome", "message", message);    
      } 
}

I have a welcome.jsp under WEB-INF/view where I'm fetching the value put in message Object.

Can someone let me know where I'm going wrong?

Thanks, Sayantani

evidently however you added the jars to the classpath didn't work. — Nathan Hughes, Feb 13 '15 at 14:18
Is there a reason you're not using Spring Boot and Maven or Gradle? — chrylis -cautiouslyoptimistic-, Feb 13 '15 at 14:18
Nathan, since the Controller servlet contains classes from the spring package, I can understand that the jars have been added correctly. The classes are not showing any error. Even when I click on org.springframework.web.servlet.DispatcherServlet, in the web.xml, it is redirecting me to the Dispatcher Class, though I cannot see the source. — Sayantani Roy Chaudhuri, Feb 13 '15 at 14:29
Chrylis, There is no such reason as to why I'm not using Maven or gradle, but my development tool is RAD 8.5 and I could not find enough support document to use Maven from RAD. — Sayantani Roy Chaudhuri, Feb 13 '15 at 14:31
Isn't RAD based on Eclipse? Maven is thoroughly supported with m2eclipse. — chrylis -cautiouslyoptimistic-, Feb 13 '15 at 14:44
And you have added the jars to the compile-time classpath, but clearly not runtime. — chrylis -cautiouslyoptimistic-, Feb 13 '15 at 14:45
I've created a user library with spring jars and added to my java build path. I am unable to understand where am going wrong. — Sayantani Roy Chaudhuri, Feb 13 '15 at 14:52
that's an important detail you should add to the question. (as a comment it's not visible enough.) — Nathan Hughes, Feb 13 '15 at 14:58
