How to use AJAX with JAGUAR Struts?
Dec 18, 2025

AJAX (Asynchronous JavaScript and XML) is a powerful web development technique that allows web pages to update asynchronously by exchanging small amounts of data with the server in the background, without reloading the entire page. When it comes to integrating AJAX with Jaguar Struts, it can significantly enhance the user experience of web applications. As a Jaguar Struts supplier, I'd like to share some insights on how to effectively use AJAX with Jaguar Struts.
Understanding the Basics of AJAX and Jaguar Struts
Before diving into the integration process, it's essential to have a clear understanding of AJAX and Jaguar Struts. AJAX uses a combination of technologies, including HTML, CSS, JavaScript, and XML (although JSON is more commonly used nowadays), to create dynamic web pages. It enables web applications to make asynchronous requests to the server and update parts of the page without refreshing the whole page.
Jaguar Struts, on the other hand, is a framework that provides a set of tools and components for building web applications in Java. It follows the Model - View - Controller (MVC) architectural pattern, which separates the business logic, presentation logic, and data. Struts helps developers manage the flow of requests and responses in a web application, making it easier to develop and maintain large - scale web projects.
Setting Up the Environment
To use AJAX with Jaguar Struts, you first need to set up a proper development environment. Here are the steps:
- Install Java and a Java IDE: You need to have Java Development Kit (JDK) installed on your machine. Popular Java IDEs like Eclipse or IntelliJ IDEA can be used for development.
- Download and Configure Struts: Download the Jaguar Struts framework from the official website. Add the necessary JAR files to your project's classpath. You also need to configure the
struts - config.xmlfile to define actions, forms, and other Struts components. - Include AJAX Libraries: There are several AJAX libraries available, such as jQuery. You can download the jQuery library and include it in your HTML pages. For example, you can add the following code to your HTML file:
<script src="https://code.jquery.com/jquery - 3.6.0.min.js"></script>
Making Asynchronous Requests with AJAX in Jaguar Struts
Once the environment is set up, you can start making asynchronous requests using AJAX in your Jaguar Struts application. Here's a step - by - step guide:
Step 1: Create a Struts Action
First, create a Struts action class that will handle the AJAX request. This class should extend the Action class provided by the Struts framework. For example:
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class AjaxAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
// Perform some business logic here
String data = "This is the response from the server";
response.setContentType("text/plain");
response.getWriter().write(data);
return null;
}
}
Step 2: Configure the Action in struts - config.xml
Add the following configuration to your struts - config.xml file to map the action class to a specific URL:
<action - mappings>
<action path="/ajaxAction" type="com.example.AjaxAction"/>
</action - mappings>
Step 3: Make an AJAX Request from the HTML Page
Use jQuery to make an AJAX request to the Struts action. Here's an example:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery - 3.6.0.min.js"></script>
<script>
$(document).ready(function () {
$("#ajaxButton").click(function () {
$.ajax({
url: "ajaxAction.do",
type: "GET",
success: function (response) {
$("#resultDiv").text(response);
},
error: function () {
alert("An error occurred");
}
});
});
});
</script>
</head>
<body>
<button id="ajaxButton">Make AJAX Request</button>
<div id="resultDiv"></div>
</body>
</html>
In this example, when the user clicks the "Make AJAX Request" button, an AJAX request is sent to the ajaxAction.do URL. If the request is successful, the response from the server is displayed in the resultDiv element.
Handling JSON Data
In modern web applications, JSON is the preferred data format for AJAX requests and responses. To handle JSON data in a Jaguar Struts application, you can use a JSON library like Jackson.
Step 1: Add Jackson Dependency
Add the Jackson library to your project's classpath. If you're using Maven, add the following dependencies to your pom.xml file:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson - databind</artifactId>
<version>2.13.0</version>
</dependency>
Step 2: Modify the Struts Action to Return JSON
Modify the Struts action class to return JSON data. For example:
import com.fasterxml.jackson.databind.ObjectMapper;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import java.util.HashMap;
import java.util.Map;
public class JsonAjaxAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
Map<String, String> data = new HashMap<>();
data.put("message", "This is a JSON response");
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(data);
response.setContentType("application/json");
response.getWriter().write(json);
return null;
}
}
Step 3: Update the AJAX Request to Handle JSON
Update the AJAX request in the HTML page to handle JSON data:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery - 3.6.0.min.js"></script>
<script>
$(document).ready(function () {
$("#jsonAjaxButton").click(function () {
$.ajax({
url: "jsonAjaxAction.do",
type: "GET",
dataType: "json",
success: function (response) {
$("#jsonResultDiv").text(response.message);
},
error: function () {
alert("An error occurred");
}
});
});
});
</script>
</head>
<body>
<button id="jsonAjaxButton">Make JSON AJAX Request</button>
<div id="jsonResultDiv"></div>
</body>
</html>
