ModelDriven Interface to get the values on success.jsp page

I wrote the code in my struts 2 application all is working fine but i am not getting attribute at succecc.jsp page. Please tell me where i am making mistake...

My Action class is

package action;

import java.util.Map;

import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

import dao.Empdao;
import model.Empmodel;
public class Empaction extends ActionSupport implements ModelDriven<Object>,SessionAware{

private static final long serialVersionUID = 1L;
    Empmodel modelobj;
    Map<String, Object> map;
    public String execute() throws Exception{
        map.put("a", modelobj.getFirstname());
        Empdao empdao = new Empdao();
        int queryResult = empdao.registration(modelobj);
        if (queryResult==0)
        {   
          addActionError("it is a dublicate entry please enter anothe id");
              return ERROR;
        }   
        else{   
         return SUCCESS;    
         }
}

    @Override
    public Object getModel() {
    modelobj = new Empmodel();
    return null;
    }

    @Override
    public void setSession(Map<String, Object> map) {
        // TODO Auto-generated method stub
        this.map =map;
    }

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
       "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
       "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.enable.DynamicMethodInvocation" value="true" />
    <constant name="struts.devmode" value="true" />
<package name="loginmodel" extends="struts-default">
    <action name="emplogin" class="action.Empaction">
        <result name="input">/Registration/empregistration.jsp</result>
        <result name="success">/Registration/success.jsp</result>
        <result name="error">/Registration/empregistration.jsp</result>
    </action>
</package>
</struts>

success.jsp is

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

</head>
<body>
    Registration successful
    <s:property value="#session.a" />
</body>
</html>

Empmodel class

package model;

public class Empmodel {

public long getMobileno() {

public int getPincode() {

public void setPincode(int pincode) {
    this.pincode = pincode;
}

First you need to correct your action, the idea of using ModelDriven is that you push your model onto the stack, you are pushing null.
You can also get rid of the SessionAware if that's all you are using it for.

public class Empaction extends ActionSupport implements ModelDriven<Empmodel> {

    private static final long serialVersionUID = 1L;
    Empmodel modelobj = new Empmodel();

    public String execute() throws Exception {

        Empdao empdao = new Empdao();

        int queryResult = empdao.registration(modelobj);

        if (queryResult == 0) {
            addActionError("it is a dublicate entry please enter anothe id");
            return ERROR;
        } else {

            return SUCCESS;
        }
    }

    @Override
    public Empmodel getModel() {
        return modelobj;
    }
}

Now your Empmodel is at the top of the ValueStack so this will work:

<s:property value="%{firstName}"/>

Make sure that the ModelDrivenInterceptor is on your interceptor stack.

why using session,if you can achieve this using valuestack, you have many ways to achieve this

using ognl

<s:property value="modelobj.firstname "/>

using scriptlet

<%
String fName=(String)session.getAtribute("a");

%>
