Try this, will help you in Struts 2.0.14 with jsonplugin-0.32.jar.

struts.xml:

     
        
            
        
              
            example/HelloWorld.jsp
        
    

action class Helloworld.java:

package prabhakar;

import glb.DB;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

/**
 * Prabhakar
 */
public class HelloWorld  {


    private List stateList= new ArrayList();
    private List regnList= new ArrayList();

    private Integer stateId;
    public Integer getStateId()
    {
    return this.stateId;
    }
    public void setStateId(Integer stateId)
    {
    this.stateId=stateId;
    }
    public List getStateList() {
        return stateList;
    }

    public void setStateList(List stateList) {
        this.stateList = stateList;
    }
     public void setRegnList(List regnList) {
        this.regnList = regnList;
    }
    public List getRegnList() {
        return regnList;
    }

    public String execute() throws Exception {

        stateList=DB.getStateData()//
        if(stateId !=null)
          {
         regnList=DB.getRegnByStateId(stateId);
          }

        //setMessage(getText(MESSAGE));
        return "success";
    }

    /**
     * Provide default valuie for Message property.
     */

}

You can directly call HelloWorld.action to view the JSON data or else you can bind the JSON data to a form element below.

JSP page HelloWorld.jsp:

  /*
     Prabhakar
  */

<%@ page contentType="text/html; charset=UTF-8" %>

<%@ taglib prefix="s" uri="/struts-tags" %>

    


  



    
        State List 
        Regn List 
    

Happy coding :)
