I'm new to struts 2 and I keep getting this error message 'No result defined for action com.jjpeople.action.HelloAction and result success' while I think I have properly refrenced it.What might be the problem?

Action class

package com.jjpeople.action;

import com.jjpeople.model.Hello;
import com.opensymphony.xwork2.ActionSupport;

public class HelloAction extends ActionSupport 
{
    private static final long serialVersionUID = 1L;
    private Hello hello;

    public String execute() throws Exception 
    {
        hello = new Hello();
        return SUCCESS;
    }
    public Hello getMessage() 
    {
        return hello;
    }
    public void setMessage(Hello hello) 
    {
        this.hello = hello;
    }
}

In your xml file

<action name="hello" class="com.jjpeople.action.HelloAction" method="execute">                 <result name="success">/welcome.jsp</result>         </action>

result name is "success",But in your Action class you returnd "SICCESS" variable.So please check the SUCCESS variable value.

The result is struts.xml and Action didn't equals.So returned the exception you didn't be defined.
