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.

UPC-A is also known as Universal Product Code version A, UPC-A Supplement 5/Five-digit Add-On, UPC-A Supplement 2/Two-digit Add-On, UPC-A+5, UPC-A+2, UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12

Java UPC-A Generator supports:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

1. How to generate barcode UPC-A in Java class?

   8     UPCA barcode = new UPCA(); 
   9           barcode.setData("12345678912"); 
   10          barcode.drawBarcode("C://barcode-upca.gif"); 
   

   
   
   
   
2. How to create barcode UPC-A 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=12345678912&TYPE=UPCA
     
     
   • 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=12345678912&TYPE=UPCA" />

   25               response.setDateHeader("Expires", 0); 
   26    
   27               barcode.drawBarcode(servletoutputstream);
