1. Java Codabar Introduction

Codabar is also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.

Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It was designed to be accurately read even when printed on dot-matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007.
This symbology is used by U.S. blood banks, photo labs, and on FedEx airbills. Because Codabar is self-checking, it does not define a check digit. This symbology starts and finishes with one of four possible characters A, B, C, or D.

2. Java Codabar Encoding Data Scope

Java Codabar Generator supports 16 letters.
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • - (Dash), $ (Dollar), : (Colon), / (Slash), . (Point), + (Plus)


 

3. How to Generate Codabar Barcode in Java Class?

The following Java code illustrates how to create a Codabar barcode, and output to various formats

1            Linear linear = new Linear(); 
2            linear.setType(Linear.CODABAR); 
3            linear.setData("123456789"); 
4            linear.renderBarcode("c:/barcode.gif"); 
	
5            BufferedImage bufferedImage = linear.renderBarcode();

6            byte[] barcodeBytes = linear.renderBarcodeToBytes();

7            Graphics2D g = ...
8            Rectangle2D rectangle = ... 
9            linear.renderBarcode(g, rectangle);

10           OutputStream outputStream = ...
11           linear.renderBarcode(outputStream);

  • Create a Linear barcode object (line 1)
  • Set Linear object barcode type to Codabar (line 2)
  • Set Codabar barcode data to encode (line 3)
  • Encode generated Codabar barcode into gif image file (line 4)
  • Generate Codabar and output to BufferedImage object (line 5)
  • Generate Codabar in bitmap and output to byte[] (line 6)
  • Generate Codabar and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
  • Generate Codabar and output to OutputStream (line 10-11)



 

4. How to Generate Codabar Image in Java Web Applications?

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

  1. The simplest way is to stream barcode image using our buildin barcode servlet application.

    • Download the Barcode for Java Trial Package, and unzip it.


    • Under java_barcode_trial package, copy barcode folder to your java servlet container like tomcat.


    • Restart tomcat. Now you have installed successfully.


    • To test your installation, open your web browser and navigate to
      http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODABAR


    • To create barcode image in your JSP or html page, you need pass the url to IMG tag src value. For example,
      <img src="http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODABAR" />

      Using this method, it will not generate any barcode images in your server side.


  2. The second method is to generate barcode images in your server side

    • Create a barcode image in server side 
      1            Linear linear = new Linear(); 
2            linear.setData("123456789"); 
3            linear.setType(Linear.CODABAR); 
4            linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/barcode-images/barcode.gif");


    • In your JSP or HTML page, you need use IMG tag to display generated image, like
      <img src="http://YourDomain:Port/YourWebApp/barcode-images/barcode.gif" />

6. Java Codabar Property Settings

  • Set the type property to Linear.CODABAR
    Servlet URL Parameter: "Type". Value: 0. Sample: &Type=0
  • Set the data property with the value to encode.
    Type is String.
    • Valid Data Scope:
      • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
      • - (Dash), $ (Dollar), : (Colon), / (Slash), . (Point), + (Plus)
    • Valid Data Format: Valid Codabar data includes the above chars only, do not include Codabar Start and Stop chars ("A", "B", "C", and "D") in this property.
    • Sample: "123456789012"
    Servlet URL Parameter: Data.
  • addCheckSum property is not applied here. Codabar does not require any check sum.
  • Set N property, Wide bar vs Narrow bar ratio. Valid values are from 2.0f to 3.0f, inclusive.
    Default is 2.0f.
    Servlet URL Parameter: N. Sample: &N=3
  • Barcode image size settings:
    • Set property uom (Unit of Measure) for properties X, Y, leftMargin, rightMargin, topMargin and bottomMargin.
      Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
      Servlet URL Parameter: "UOM". Value: 0 (pixel), 1 (cm), 2 (inch). Sample: &UOM=0
    • Set the X (for barcode module width) and Y (for barcode module height) properties.
      Both types are float. Default X is 3. Y is 75.
      Servlet URL Parameter: "X", "Y". Sample: &X=3&Y=75
    • Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
      Default values are 0 for all 4 margin settings.
      Servlet URL Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin". Sample: &LeftMargin=0
    • Set the resolution property (Value is expressed in DPI - Dots per inch).
      Default is 72 dpi.
      Servlet URL Parameter: "Resolution". Sample: &Resolution=72
  • Setting up text style in barcode image:
    • Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
