Java GS1 DataBar Generator to generate, create DataBar barcode in Java Class, JSP, Servlet application using Java Barcode Generator Library

Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.

The GS1 DataBar (formerly RSS) family consists of the following versions:

• GS1 DataBar-14
• GS1 DataBar-14 Truncated
• GS1 DataBar-14 Stacked
• GS1 DataBar-14 Stacked Omnidirectional
• GS1 DataBar Limited (formerly RSS Limited)
• GS1 DataBar Expanded (formerly RSS Expanded)
• GS1 DataBar Expanded Stacked (formerly RSS Expanded Stacked)

1. How to generate barcode in Java class?

   8     Code39 barcode = new Code39();
   9           barcode.setData("0123456789");
   10          barcode.drawBarcode("C://barcode.gif");
   

   
   
   
   
2. How to create barcode image in html or jsp pages?
   
   
   • Under demo package, copy barcode folder and its contents to your tomcat.
     
     
   • Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE39
     
     
   • To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
     For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE39" />
     
     
   
   
   
3. How to create barcode image in Java Servlet?

   1    package com.onbarcode.barcode.test;
   2    
   3    import com.onbarcode.barcode.AbstractBarcode;
   4    import com.onbarcode.barcode.Code39;
   5    
   6    import javax.servlet.http.HttpServlet;
   7    import javax.servlet.http.HttpServletRequest;
   8    import javax.servlet.http.HttpServletResponse;
   9    import javax.servlet.ServletException;
   10   import javax.servlet.ServletOutputStream;
   11   
   12   public class TestServlet extends HttpServlet
   13   {
   14       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException
   15       {
   16           try {
   17               Code39 barcode = new Code39();
   18               barcode.setData("0123456789");
   19   
   20               ServletOutputStream servletoutputstream = response.getOutputStream();
   21   
   22               response.setContentType("image/jpeg");
   23               response.setHeader("Pragma", "no-cache");
   24               response.setHeader("Cache-Control", "no-cache");
   25               response.setDateHeader("Expires", 0);
   26   
   27               barcode.drawBarcode(servletoutputstream);
   28   
   29           } catch (Exception e) {
   30               throw new ServletException(e);
   31           }
   32       }
   33   }
