Stanadard 2 of 5 is a low-density numeric symbology that has been with us since the 1960s. It has been used in the photofinishing and warehouse sorting industries, as well as sequentially numbering airline tickets. The symbology is called "2 of 5" due to the fact that digits are encoded with 5 bars, 2 of which are always wide (and the remaining three are narrow).

Standard 2 of 5 is a very simple symbology in that all encoding information is encoded in the width of the bars. The spaces in the barcode exist only to separate the bars themselves. Additionally, a bar may either be wide or narrow, a wide bar generally being 3 times as wide as a narrow bar. The exact size of the spaces is not critical, but is generally the same width as a narrow bar.

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

1            Linear linear = new Linear(); 
2            linear.setData("123456789"); 
3            linear.setType(Linear.CODE2OF5); 
4            linear.renderBarcode("c:/barcode.gif"); 

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

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

1. 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/linear?Data=123456789&Type=CODE2OF5
     
     
   • To create barcode image in your JSP or html page, you can pass the url to IMG tag src value. For example, <img src="http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE2OF5" />
     
     
2. The second method is similar with the way to generate barcode in Java applications.
   
   
   • Create a barcode image in server side

     1            Linear linear = new Linear(); 
     2            linear.setData("123456789"); 
     3            linear.setType(Linear.CODE2OF5); 
     4            linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/bimages/barcode.gif"); 
     
     
     

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

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

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

Import class BarcodeJasperFactory 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(BarcodeJasperFactory.createLinear(2, "47082163"))]]></imageExpression> 
</image>

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

Developers can also extend or modify BarcodeJasperFactory class to meet their own requirements. Complete BarcodeJasperFactory.java Source Code
