How to Generate Barcode Image in Web Applications?

1. The simplest way - How to generate barcode image is to use our Build-in Barcode Generation web application (The application is included in Barcode for Java trial package. download it).
   And it will not save generated barcode images in your server side. Follow the steps to see how:
• Copy folder barcode, under BarcodeLib_JavaBarcode_Trial (or BarcodeLib_JavaBarcode_Production), to your java servlet container like Tomcat.
• Restart Tomcat, and test your installation, open web browser and navigate to:
  http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE128
• To create & insert barcode images in your JSP or html pages, you can pass the url to IMG tag src value. For example,
  <img src="http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE128" />
2. The second method - Similar with the way to generate barcode in Java class.
• Create a barcode & save the barcode image to your server side:
  Linear linear = new Linear();
  linear.setData("123456789");
  linear.setType(Linear.CODE128);
  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" />
