create struts application in myeclipse-IGI

To create a Struts 2 application in MyEclipse, you can follow these steps:

Launch MyEclipse: Open the MyEclipse IDE and create a new workspace.
Create a new project: Select the "File" menu and choose "New" and then "Project". In the "New Project" dialog box, select "Web" and then "Web Project". Give a name to the project, and click "Next".
Select the Struts 2 framework: In the "New Web Project" dialog, select the "Struts 2 Project" option and click "Next".
Configure the Struts 2 project settings: In the "Struts 2 Project" dialog box, enter the project details such as the Struts version, package namespace, and default package location. Click "Finish" to create the project.
Create an action class: Once the project is created, you can create a new Java class that extends the ActionSupport class, which provides several helper methods for processing user input. In this class, you can define a method that handles a user request and returns a result.

For example, you can create a class named HelloAction that has a method named execute() that returns a result named "success".

re‮t ref‬o:theitroad.com

package com.example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloAction extends ActionSupport {

    public String execute() {
        return "success";
    }
}

Define the view: The view is the user interface that the user interacts with. In Struts 2, you can use JSP pages or FreeMarker templates to define the view. Create a JSP page that displays a welcome message to the user.

<%@ page contentType="text/html; charset=UTF-8" language="java" %>
<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <h1>Hello, Struts!</h1>
  </body>
</html>

Configure the application: Struts 2 requires several configuration files to work correctly. You need to configure the struts.xml file to specify the application's settings and dependencies. In this file, you can define a mapping between the user request and the action class, and specify the result to be returned.

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
    "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
  <package name="default" namespace="/" extends="struts-default">
    <action name="hello" class="com.example.HelloAction">
      <result name="success">/hello.jsp</result>
    </action>
  </package>
</struts>

Deploy and test the application: You can deploy the Struts 2 application on a web server such as Apache Tomcat, and test it by entering the URL of the action in a web browser.

For example, if you have named the action "hello", you can access it by entering the following URL in the browser:

http://localhost:8080/yourapp/hello

This should display the welcome message on the web page.

Overall, creating a Struts 2 application in MyEclipse involves creating a new project, defining the action class, creating the view, configuring the application, and testing it. MyEclipse provides a powerful and flexible environment for building robust web applications in Java.
