Java Codabar - Introduction


It 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.

• Draw barcodes to image files

   BarCode barcode = new BarCode(); 
    barcode.setType(BarCode.CODE39); 
    barcode.setData("0123456789"); 
    barcode.draw("C://code39.gif"); 
  

• Draw barcodes to java.io.OutputStream object

   BarCode barcode = new BarCode(); 
    barcode.setType(BarCode.CODE39); 
    barcode.setData("0123456789"); 
    barcode.draw(outputStreamObject); 
  

• Draw barcodes to java.awt.Graphics2D object

   BarCode barcode = new BarCode(); 
    barcode.setType(BarCode.CODE39); 
    barcode.setData("0123456789"); 
    barcode.draw(graphicsObject); 
  

• How to generate barcode image in html or jsp pages?

  1. Download trial package, unzip it, copy barcode folder and its contents to your Java Servlet container like Tomcat, or Jboss.
     
     
  2. Start Tomcat, navigate to http://url:port/barcode/barcode?data=0123456789&type=4
     
     
  3. To generate barcodes in html page or jsp page, insert the following html code.
     <img src="http://url:port/barcode/barcode?data=0123456789&type=4" />
     
     

• How to generate barcode image in Java Servlet?

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws
     ServletException 
      { 
          try { 
              BarCode barcode = new BarCode();
              barcode.setType(BarCode.CODE39); 
              barcode.setData("0123456789"); 
               
              ServletOutputStream sout = response.getOutputStream(); 
   
              response.setContentType("image/jpeg"); 
              response.setHeader("Pragma", "no-cache"); 
              response.setHeader("Cache-Control", "no-cache"); 
              response.setDateHeader("Expires", 0); 
   
              barcode.drawBarcode(sout); 
   
          } catch (Exception e) { 
              throw new ServletException(e); 
          } 
      }
