Java Code EAN-13 Generator - Overview

Java EAN-13 generator is a mature and reliable Java barcode generation component for creating EAN-13 barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects. High-quality EAN-13 barcode images can be drawn and printed into GIF, BMP, PNG, JPEG/JPG & TIFF formats with Java EAN-13 barcode generator. Rich barcode options are provided to customize EAN-13 barcode properties in accordance with your needs.

EAN-13 information:

EAN-13: a super set of UPC-A, was developed by the International Article Numbering Association (EAN) in Europe and now is used worldwide to mark products often sold at retail point of sale.

Available encoding data:

numeric digits: 0-9

The structure of a EAN-13:

1. The company number.
2. The item number.
3. The item reference.
4. Check digit


Java EAN-13 Generator Implementation to Generate EAN-13

1. Generate EAN-13 in Java class with the changing of barcode properties.

// 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. Generate & encode EAN-13 to EPS with changing the values concerned.

// 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. Generate & encode EAN-13 in html or jsp pages.

1. Copy barcode folder and its contents from demo package to Apache Tomcat.

2. Start Apache Tomcat, go to http://YourDomain:Port/barcode/barcode?DATA=1234567&TYPE=EAN13

3. Insert an image tag (img) into your page. For example,

<imgsrc="http://YourDomain:Port/barcode/barcode?DATA=1234567&TYPE=EAN13" />


4. Two ways to set the width and height of generated barcode ISSN image.

1. Set the values of the barcodeWidth and barcodeHeight properties.
or
2. Set X (bar module width) and Y (bar module height) values
