Java Data Matrix Generator

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.

Data Matrix code is a two-dimensional matrix barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.

Java Data Matrix Generator supports:

• all 128 characters of ASCII
  
  
• values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

1. How to generate barcode Data Matrix in Java class?

   8     DataMatrix barcode = new DataMatrix(); 
   9           barcode.setData("0123456789"); 
   10         barcode.drawBarcode("C://barcode-datamatrix.gif"); 
   

   
   
   
   
2. How to create barcode Data Matrix 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=0123456789&TYPE=DATAMATRIX
     
     
   • 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=0123456789&TYPE=DATAMATRIX" />
     
     
   
   
   
3. How to create barcode Data Matrix image in Java Servlet?

   
   1    package com.onbarcode.barcode.test;

   11    
   12   public class TestServlet extends HttpServlet 
   13   { 
   14       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
   15       { 
   16           try { 
   17               DataMatrix barcode = new DataMatrix(); 
   18               barcode.setData("0123456789"); 
   19                
   20               ServletOutputStream servletoutputstream = response.getOutputStream(); 
   21    
   22               response.setContentType("image/jpeg"); 
   23               response.setHeader("Pragma", "no-cache"); 
   24               response.setHeader("Cache-Control", "no-cache"); 
   25               response.setDateHeader("Expires", 0); 
   26    
   27               barcode.drawBarcode(servletoutputstream); 
   28    
   29           } catch (Exception e) { 
   30               throw new ServletException(e); 
   31           } 
   32       } 
   33   } 
   34
