Struts 2 Iterator Tag Example

Struts 2 iterator tag is useful for iterating a value which of type java.util.Collections or java.util.Iterator. This example demonstrates with a simple iteration block which is taking the users list and displaying the list of users in the list.

1. Create Data Bean

Create a bean to hold the user details.


public class UserDetails {
	private String name;
	private String city;
	public UserDetails(String... args){ = args[0]; = args[1];
	public String getName() {
		return name;
	public void setName(String name) { = name;
	public String getCity() {
		return city;
	public void setCity(String city) { = city;


2. Create Struts 2 Action

Create a action class for storing the values and passing the UserDetails object to the screen.


import java.util.ArrayList;

public class Struts2Iteration {
	private ArrayList<UserDetails> users;

	public ArrayList<UserDetails> getUsers() {
		return users;

	public void setUsers(ArrayList<UserDetails> users) {
		this.users = users;
	public String execute(){
		users = new ArrayList<UserDetails>();
		users.add(new UserDetails("Krishna","Bangalore"));
		users.add(new UserDetails("Rahul","Bangalore"));
		users.add(new UserDetails("Arjun","Bangalore"));
		return "success";

3. Iterator Example

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
<title>Struts 2 Iteration Example</title>
   <B>Struts 2 Iteration Example</B>
   <form action="iterationexample">
     <s:iterator value="users">
		<s:property value="name"/> ,
		<s:property value="city"/><br/>

4. Struts.xml configurations

Create a simple struts.xml configuration file with action mappings.

<?xml version="1.0" encoding="UTF-8"?>
   "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
	<constant name="struts.devMode" value="true" />
	<package name="tags" extends="struts-default">
		<action name="iterationexample" class=""
			<result name="success">/index.jsp</result>
