Code 39, the first alpha-numeric symbology to be developed, is still widely used-especially in non-retail environments. It is the standard bar code used by the United States Department of Defense, and is also used by the Health Industry Bar Code Council (HIBCC).

Our library fully complies with ISO/IEC 16388 (Second edition 2007-05-15).

Sample of a Code 39 Barcode

Sample of a Code 39 Extension Barcode

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.CODE39); 
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=CODE39
     
     
   • 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=CODE39" />
     
     
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.CODE39); 
     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(3, "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
