This guide provides a quick start to get you up and running with Struts 2, one of the most popular open-source web application frameworks in the Java ecosystem.

Overview

Struts 2 is built on top of the Apache Struts framework and offers a robust and powerful solution for developing web applications. It follows the Model-View-Controller (MVC) architecture, making it easier to manage the presentation, business logic, and data of a web application.

Getting Started

  1. Download Struts 2:

  2. Set Up Your Project:

    • Create a new Java web project in your preferred IDE (e.g., Eclipse, IntelliJ IDEA).
    • Add the Struts 2 JAR files to your project's classpath.

  3. Create a Web.xml Configuration:

    • Add the necessary filters and servlet mappings to your web.xml file to configure Struts 2 for your web application.

  4. Create a Struts 2 Action Class:

    • Create a Java class that extends com.opensymphony.xwork2.ActionSupport to define your action.
    • Implement the necessary methods to handle the business logic of your application.

  5. Create a JSP View:

    • Create a JSP page to display the output of your action.
    • Use Struts 2 tags to interact with your action and display dynamic content.

Example

Here's a simple example of a Struts 2 action and view:

Action Class (MyAction.java):

package com.example;

import com.opensymphony.xwork2.ActionSupport;

public class MyAction extends ActionSupport {
    public String execute() {
        return SUCCESS;
    }
}

JSP View (index.jsp):

<%@ taglib uri="http://struts.apache.org/tags-struts" prefix="struts" %>
<html>
<head>
    <title>Struts 2 Quickstart</title>
</head>
<body>
    <h1>Welcome to Struts 2!</h1>
    <struts:action name="myAction">
        <struts:forward name="success" path="/success.jsp" />
    </struts:action>
</body>
</html>
