Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.

 

Barcode EAN-13 Introduction

EAN-13 barcode (originally European Article Number) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States. The EAN-13 barcode is defined by the standards organisation GS1. The numbers encoded in EAN-13 bar codes are product identification numbers which are called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.

 

Java EAN 13 Generator - Valid Data Scope

1. How to generate barcode EAN-13 in Java class?

   // Create Java EAN13 object 
   EAN13 barcode = new EAN13(); 
   
   // Set EAN13 data text to encode. It must be 12 digits, without last checksum digit.
   barcode.setData("012345678912"); 
   
   // Generate EAN13 barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate EAN13 barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-ean13.gif"); 
   
   // Generate EAN13 barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-ean13.jpg"); 
   
   

   
   
   

2. How to generate & encode EAN-13 barcodes to EPS?

   // Create Java EAN13 object 
   EAN13 barcode = new EAN13(); 
   
   // Set EAN13 data text to encode. It must be 12 digits, without last checksum digit.
   barcode.setData("012345678912"); 
   
   // Generate EAN13 barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-ean13.eps"); 

   
   
   

3. How to create & encode EAN-13 image in html or jsp pages?

   
   
   
   • Under demo package, copy barcode folder and its contents to your tomcat.
     
     
   • Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13
     
     
   • To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
     For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13" />
     
     
   
   
   

4. How to create & print barcode EAN-13 image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.EAN13; 
   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 { 
               EAN13 barcode = new EAN13(); 
               barcode.setData("012345678912"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
                 
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate EAN13 barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   }
