Rendering Barcode to Servlet in Java

Introduction

In the fast-paced world of technology, creating and rendering barcodes has become an integral part of various applications. Aspose.BarCode for Java provides a powerful and versatile solution for generating barcodes seamlessly. This tutorial will guide you through the process of rendering barcodes to a Servlet in Java using Aspose.BarCode, allowing you to enhance your applications with efficient barcode functionalities.

Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

• Java Development Environment: Ensure you have a Java development environment set up on your machine.

• Aspose.BarCode for Java Library: Download and install the Aspose.BarCode for Java library from the download link.

Import Packages

To begin, import the necessary packages into your Java project. These packages will provide the essential tools for barcode generation and servlet functionality.

import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.OutputStream;
import javax.imageio.ImageIO;

import javax.servlet.*;
import javax.servlet.http.*;

import com.aspose.barcode.generation.BarcodeGenerator;

Now, let’s break down the process into simple, actionable steps.

Step 1: Create a Servlet Class

Begin by creating a servlet class that extends HttpServlet.

public class RenderBarcodeToServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

Step 2: Implement doGet Method

Implement the doGet method within the servlet class. This method will handle the barcode generation and rendering process.

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        BarcodeGenerator bb = new BarcodeGenerator(com.aspose.barcode.EncodeTypes.CODE_128, "1234567");
        BufferedImage image = bb.generateBarCodeImage();

Step 3: Set Response Parameters

Configure the response parameters, specifying the content type as “image/png.”

        response.setContentType("image/png");
        OutputStream outputStream = response.getOutputStream();

Step 4: Write Image to Output Stream

Write the generated barcode image to the output stream.

        ImageIO.write(image, "png", outputStream);
        outputStream.close();
    }
}
//ExEnd: RenderBarcodeToServlet

And that’s it! With these simple steps, you’ve successfully integrated barcode rendering into your Java Servlet.
