1. Barcode Introduction

The ISSN (International Standard Serial Number) is an eight-digit number which identifies periodical publications as such, including electronic serials.

The ISSN is a numeric code which is used as an identifier: it has no signification in itself and does not contain in itself any information referring to the origin or contents of the publication.

The ISSN takes the form of the acronym ISSN followed by two groups of four digits, separated by a hyphen. The eighth character is a control digit calculated according to a modulo 11 algorithm on the basis of the 7 preceding digits; this eighth control character may be an "X" if the result of the computing is equal to "10", in order to avoid any ambiguity.

Sample of an ISSN Barcode

Add-On or Supplement code

The Add-On Symbols were designed to encode information supplementary to that in the main bar code symbol on periodicals and paperback books. The Add-On can be composed of 2 digits only.

2. Encoding Data Scope

ISSN Barcode for Java supports.

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

3. How to Generate Barcode Image in Standalone Applications?

The following code illustrates how to create a barcode in a Java class

1            Barcode barcode = new Barcode(); 
2            barcode.setData("123456789"); 
3            barcode.setType(Barcode.CODE39); 
4            barcode.createBarcodeImage("c:/code39.gif");

Create a Barcode object (line 1)
set Barcode object properties (line 2 - 3)
save into gif file (line 4)

4. How to Generate Barcode Image in Web Applications?

There are two ways to create barcode images in your Java web applications.

This is the simplest way to stream barcode image using our provided barcode servlet classes.

And it will not save barcode images in your server side.
- Under demo package, copy barcode folder to your java servlet container like tomcat.
- To test your installation, goto http://YourDomain:Port/barcode/barcode?Data=123456789&Type=CODE39
- To create barcode image in your JSP page, you can pass the url to IMG tag src value. For example, <img src="http://YourDomain:Port/barcode/barcode?Data=123456789&Type=CODE39" />

The second method is similar with the way to generate barcode in Java applications.

Create a barcode image in server side

1            Barcode barcode = new Barcode(); 
2            barcode.setData("123456789"); 
3            barcode.setType(Barcode.CODE39); 
4            barcode.createBarcodeImage("C:/Tools/Tomcat 5.5/webapps/YourWebApp/bimages/code39.gif");

In your JSP page, you can using IMG tag to display generated image, like <img src="http://YourDomain:Port/YourWebApp/bimages/code39.gif" />

5. How to Generate Barcode Image in JasperReports?

The following jasper xml content illustrates how to insert a barcode into JasperReports

<import value="com.barcodelib.barcode.BarcodeFactory"/>

Import class BarcodeFactory to report.

<image scaleImage="Clip" hAlign="Center"> 
    <reportElement x="50" y="110" width="515" height="120"/> 
    <graphicElement/> 
    <imageExpression class="net.sf.jasperreports.engine.JRRenderable">
     <![CDATA[new com.barcodelib.barcode.BarcodeJasperRenderer(BarcodeFactory.createLinear(13, "0470821632"))]]></imageExpression> 
</image>

Please go to class BarcodeFactory in Java doc for all methods to create linear barcode.

Developers also can extend BarcodeFactory class to meet their own requirements. Complete BarcodeFactory.java Source Code

6. How to Save Barcode Image?

Just call Barcode object method createBarcodeImage, e.g. barcode.createBarcodeImage("c:/code39.gif");

7. Barcode Property Settings

Category	Attribute/Method	Servlet Attribute	Default Value	Description
Basic Settings
	type	Type	CODE128 (22)	View all supported barcode types and values. Use the number value for the java bean class and the number or text value for the servlet. For example, the servlet query url should include: Type=CODE128 or Type=22
	data	Data	""	This is the barcode text to be encoded. The type is String. EAN 8: User should only provide 7 digits, and DO NOT include last digit checksum character. EAN 13: User should only provide 12 digits, and DO NOT include last digit checksum character. UPCA: User should only provide 11 digits, and DO NOT include last digit checksum character. UPCE: User should only provide 6 digits, and DO NOT include last digit checksum character.
	sData	SData	""	Supplement data for ISBN, ISSN, EAN 8, EAN 13, UPCA, UPCE only. The type is String.
	addCheckSum	AddCheckSum	true	Valid values are true and false. If barcode type check sum is compulsory or not applied, addCheckSum will not work. Please check each barcode symbologies to get more details.
	processTilde	ProcessTilde	true	For barcode Code 128 only. Set the ProcessTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is true. ~NNN: is used to represent the ASCII character with the value of NNN.
Codabar
	codabarStartChar	CodabarStartChar	A	One of four possible start characters (A, B, C, or D).
	codabarStopChar	CodabarStopChar	A	One of four possible stop characters (A, B, C, or D).
UPC-E
	UPCENumberSystem	UPCENumberSystem	0	Valid values are 0 and 1. The default is 0. UPC-E may only be used if the number system is 0 or 1. The characters encoded are encoded with odd and even parity from the left-hand columns of the EAN-13 character formats in the table previously provided. The parity used for each character depends on the number system (0 or 1) and the check digit from the original UPC-A barcode.
Barcode Image Style
	uom	UOM	0 (pixel)	Unit of measure for barcode size settings, type is float, default is 0 (pixel). Valid values are 0 (pixel), 1 (CM), 2 (Inch)
	resolution	Resolution	96	Image resolution. Default is 96 DPI.
	barWidth	BarWidth	0	Bar cell width, type is float. Its unit of measure is decided by uom.
	leftMargin	LeftMargin	0	The left margin. Its unit of measure is decided by uom.
	rightMargin	RightMargin	0	The right margin. Its unit of measure is decided by uom.
	topMargin	TopMargin	0	The top margin. Its unit of measure is decided by uom.
	bottomMargin	BottomMargin	0	The bottom margin. Its unit of measure is decided by uom.
	showText	ShowText	true	If this value is true (T in servlet), barcode data will be displayed with the barcode. The servlet convert "T" to true and "F" to false.
	textFont	TextFont	Arial	The font used to display text in barcode image. To change the font, use the following format: Font font = new Font("Arial", Font.BOLD, 13); barcode.setTextFont(font); and to change the font in the servlet, use this format: &TextFont=Arial\|Bold\|13
	imageFormat	ImageFormat	gif	Valid values are "gif" and "jpeg". This setting is only valid in Servlet not in bean class.
