Java Barcode EAN-13 Generator Introduction
Top
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

Java EAN 13 Generator encodes:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to Generate EAN-13 in Java Class?
Top
Provided below is some Java sample codings for creationg EAN-13 barcode images in Java Class. To view more EAN-13 barcode settings, see here: Java EAN-13 Generator Demo Source Code
// 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");

// Generate EAN13 barcode & encode into EPS
barcode.drawBarcode2EPS("C://barcode-ean13.eps");
How to Create EAN-13 Image in Html or JSP Pages?
Top
  1. Under demo package, copy barcode folder and its contents to your tomcat.
  2. Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13
  3. To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
  4. For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13" />
