Java Barcode 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.

 

GS1 DataBar Introduction

The GS1 DataBar (formerly RSS) family consists of the following versions:

  • GS1 DataBar-14
  • GS1 DataBar-14 Truncated
  • GS1 DataBar-14 Stacked
  • GS1 DataBar-14 Stacked Omnidirectional
  • GS1 DataBar Limited (formerly RSS Limited)
  • GS1 DataBar Expanded (formerly RSS Expanded)
  • GS1 DataBar Expanded Stacked (formerly RSS Expanded Stacked)

How to Generate GS1-DataBar in Java Class?
Top
Below is the sample code for generating GS1-DataBar in Java Class.
// Build Java GS1-DataBar barcode object 
GS1DataBar barcode = new GS1DataBar();

// Encode GS1-DataBar data
barcode.setData("GS1DataBar-JAVA");

// Generate GS1DataBar barcode & print into Graphics2D object
barcode.drawBarcode("Java Graphics2D object");

// Generate GS1DataBar barcode & encode into GIF format
barcode.drawBarcode("C://barcode-gs1-databar.gif");

// Generate GS1DataBar barcode & render into JPEG format
barcode.drawBarcode("C://barcode-gs1-databar.jpg");

// Draw GS1DataBar barcode & paint into EPS image format
barcode.drawBarcode2EPS("C://barcode-gs1-databar.eps");
How to Create & Encode GS1-DataBar 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=11111555551234&TYPE=GS1DataBar
  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=11111555551234&TYPE=GS1DataBar"/>

try {
GS1DataBar barcode = new GS1DataBar();
barcode.setData("11111555551234");

ServletOutputStream servletoutputstream = response.getOutputStream();

response.setContentType("image/jpeg");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);

// Generate EAN128 barcode & output to ServletOutputStream
barcode.drawBarcode(servletoutputstream);

} catch (Exception e) {
throw new ServletException(e);
}
}
