Java QR Code 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.

QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.

Java QR Code Generator supports:

• numeric data (digits 0 - 9);
  
  
• alphanumeric data (digits 0 - 9; upper case letters A -Z; nine other characters: space, $ % * + - . / : );
  
  
• byte data (default: ISO/IEC 8859-1);
  
  
• Kanji characters.

1. How to generate barcode QR Code in Java class?

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

   
   
   
   
2. How to create barcode QR Code 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=QRCODE
     
     
   • 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=QRCODE" />

   17               QRCode barcode = new QRCode(); 
   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   }
