Java Barcode EAN-8 Generator Introduction

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-8 Introduction

EAN-8 is a barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.

 

Java EAN-8 Generator - Valid Data Scope

Java EAN 8 Generator encodes:

  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9



 

Java Barcode EAN-8 Generation FAQ

  1. How to generate barcode EAN-8 in Java class? (Complete Java EAN-8 Generator Demo Source Code)

    // Create Java EAN8 object 
    EAN8 barcode = new EAN8(); 
    
    // Set EAN8 data text to encode. It must be 7 digits, without last checksum digit.
    barcode.setData("1234567"); 
    
    // Generate EAN8 barcode & print into Graphics2D object
    barcode.drawBarcode("Java Graphics2D object"); 
    
    // Generate EAN8 barcode & encode into GIF format
    barcode.drawBarcode("C://barcode-ean8.gif"); 
    
    // Generate EAN8 barcode & encode into JPEG format
    barcode.drawBarcode("C://barcode-ean8.jpg"); 
    
    


  2. How to generate & encode EAN-8 barcodes to EPS?

    // Create Java EAN8 object 
    EAN8 barcode = new EAN8(); 
    
    // Set EAN8 data text to encode. It must be 7 digits, without last checksum digit.
    barcode.setData("1234567"); 
    
    // Generate EAN8 barcode & encode into EPS
    barcode.drawBarcode2EPS("C://barcode-ean8.eps"); 


  3. How to create & encode EAN-8 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=1234567&TYPE=EAN8

    • 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=1234567&TYPE=EAN8"/>
