 private UserBean bean;
 public String execute() {
  return SUCCESS;
 public UserBean getBean() {
  return bean;
 public void setBean(UserBean bean) {
  this.bean = bean;

Create Bean Class

package com.dineshonjava.struts2.bean;

 * @author Dinesh Rajput
public class UserBean {

 private String userAge = "27";
 private String userPhone = "9874563210";

 public String getUserName() {
  return userName;
 public void setUserName(String userName) {
  this.userName = userName;
 public String getUserAge() {
  return userAge;
 public void setUserAge(String userAge) {
  this.userAge = userAge;
 public String getUserPhone() {
  return userPhone;
 public void setUserPhone(String userPhone) {
  this.userPhone = userPhone;
 public String getUserAddress() {
  return userAddress;
 public void setUserAddress(String userAddress) {

  <li>User Name : <s:property value="name" /></li>
  <li>User Age : <s:property value="age" /></li>
  <li>User Phone : <s:property value="phone" /></li>
  <li>User Address : <s:property value="address" /></li>
 <h4>Set value of property in session by set tag</h4>
 <s:set name="name" value="#user.userName" scope="session"/>
