1. Barcode Introduction

OneCode 4-State Customer Barcode (4-CB) is the next generation in the evolution of USPS barcode technology. It does not replace existing barcodes - it offers a more effective alternative. Partnering with the Mailing Industry, the Postal Service developed the 4-CB which increases the amount of information carried on letter and flats mail pieces and allows for expanded tracking capability, creating greater visibility into the mailstream.

4-CB is a height-modulated barcode using four distinct, vertical bar types. It encodes a 31-digit string into 65 vertical bars each representing one of four possible states: full bar, ascender, tracker, and descender.

4-State Barcode Bars

4-CB carries a payload 31 digits comprised of the following elements.

Type	Field	Digits
Tracking Code	Barcode Identifier	2 (2nd digit must be 0?)
	Special Services	3
	Customer Identifier	6
	Sequence Number	9
Routing Code	Delivery Point ZIP Code	0, 5, 9, or 11

Table 1 - USPS OneCode SOLUTION Barcode Data Fields

For each of the fields in Table 1, except the Routing Code, leading or trailing zeros shall be provided to achieve the correct size. Spaces and nulls are not acceptable characters for padding. For ZIP Codes, which have one of four lengths, encoding shall provide padding beyond the digits to be encoded. No error detection and correction, such as a checksum with POSTNET or PLANET, shall be included as part of the data fields. The OneCode Barcode Data Fields are described as follows:

The Barcode Identifier is assigned by USPS for the type of tracking service. This is two digits, with the second digit in the range of 0-4
The Special Services is assigned by USPS for any special services on the mailpiece. The allowable encoding range is 000-999
The Customer Identifier is assigned by USPS as a unique identifier for each OneCode SOLUTION customer. The allowable encoding range is 000000?99999
The Sequence Number is assigned by the mailer for tracking mailpieces. The allowable encoding range is 000000000-999999999
The Delivery Point ZIP Code is assigned by the mailer for routing the mailpiece. This replaces POSTNET for routing the mailpiece to its final delivery point. The length may be 0, 5, 9, or 11 digits. The allowable encoding ranges are no ZIP Code, 00000-99999, 000000000-999999999, and 00000000000-99999999999

2. Encoding Data Scope

Onecode 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)

	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.
