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.

 

GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.

 

Java EAN 128/GS1 128 Generator supports:

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

 
Java EAN 128/GS1 128 Generator in Java Class: com.onbarcode.barcode.EAN128

Category	Class Properties	Servlet Properties	Default	Comments
Basic	data	DATA	""	value to encode
	addCheckSum	ADD-CHECK-SUM	true	addCheckSum property is not applied. Barcode Library will automatically add a check sum in the end.
EAN 128 Special	processTilde	PROCESS-TILDE	false	Set the processTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is false. ~NNN: is used to represent the ASCII character with the value of NNN. NNN is from 000 - 255.
Size Related	uom	UOM	0	Unit of meature for all size related setting in the library. 0: pixel; 1: inch; 2: cm.
	X	X	1	width of barcode module (narrow bar), default is 1 pixel
	Y	Y	30	barcode module height, default is 30 pixel
	barcodeWidth	BARCODE-WIDTH	0	generted barcode image width
	barcodeHeight	BARCODE-HEIGHT	0	generted barcode image height

Text & Color	showText	SHOW-TEXT	true	If true, display barcode data text, otherwise do not display.
	showCheckSumChar	SHOW-CHECKSUM-CHAR	true	If true, display the check sum character in the end of data, if there is a check sum.

Java Barcode Generation FAQ?

1. How to generate barcode in Java class?

   8     Code39 barcode = new Code39(); 
   9           barcode.setData("0123456789"); 
   10          barcode.drawBarcode("C://barcode.gif"); 
   

   
   
   
   
2. How to create barcode 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=CODE39
     
     
   • 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=CODE39" />
