How to Generate Barcodes in Java Class?
Here is the Java sample codes for generating a Code 128 in Java Class, please copy to your project for a test. Developers can call barcode.drawBarcode() method to draw barcode on image file or paint barcode in the memory.
// Select a barcode type to create a Java barcode object 
Code128 barcode = new Code128();

// Set barcode data text to encode

// Set barcode data text to encode

// Generate barcode & encode into GIF format

// Generate barcode & encode into JPEG format

// Generate barcode & encode into EPS format

// Generate barcode & print into Graphics2D object
barcode.drawBarcode("Java Graphics2D object");
How to Generate Barcodes in html or JSP Pages with Tomcat?
  1. Under demo package, copy barcode folder and its contents to your tomcat webapps file
  2. Start tomcat, and navigate to http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE128
  3. To create bar code images in html or jsp pages, you can insert an image tag (img) into your page.
  4. Demo tag: <img src="http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE128" />
How to Create & Print Barcode Image in Java Servlet Class?
import com.onbarcode.barcode.AbstractBarcode;
import com.onbarcode.barcode.Code128;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;

public class BarcodeServlet extends HttpServlet
 public void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException
  try {
   Code128 barcode = new Code128();

   ServletOutputStream servletoutputstream = response.getOutputStream();

   response.setHeader("Pragma", "no-cache"); 
   response.setHeader("Cache-Control", "no-cache");
   response.setDateHeader("Expires", 0);
   // Generate Code-128 barcode & output to ServletOutputStream
  catch (Exception e) {
   throw new ServletException(e);
