Java UPC-E - Introduction


This Symbology is also known as Universal Product Code version E, UPC-E Supplement 5/Five-digit Add-On, UPC-E Supplement 2/Two-digit Add-On, UPC-E+5, UPC-E+2, UPC-E0, E0, UPC-E1, E1, GTIN-12 with lead "0", GS1-12, UCC-12

UPC-E is a variation of UPC-A which allows for a more compact barcode by eliminating "extra" zeros.
Since the resulting UPC-E barcode is about half the size as an UPC-A barcode, UPC-E is generally used on products with very small packaging where a full UPC-A barcode couldn't reasonably fit.

    //Create BarCode object in Java
    BarCode barcode = new BarCode(); 
    
    //Set barcode symbology type to UPC-E
    //IBarCode.UPCE for UPC-E without supplement code
    //IBarCode.UPCE_2 for UPC-E with 2 digits supplement code
    //IBarCode.UPCE_5 for UPC-E with 5 digits supplement code
    barcode.setType(IBarCode.UPCE_2); 
    
    //Set UPC-E encoding code value. It should be 6 digits.
    barcode.setData("012345"); 
    
    //UPC-E supplement code. It should be 2 or 5 digits.
    barcode.setSupData("01");
    
    
    //Set UPC-E image size
    barcode.setUOM(IBarCode.UOM_PIXEL);        // UPC-E unit of measure
    barcode.setResolution(72);                 // UPC-E image resolution in dpi
    barcode.setX(3);                           // UPC-E bar module width (X dimention)
    barcode.setY(50);                          // UPC-E bar module height (Y dimention)
    barcode.setLeftMargin(0);		       // UPC-E image left margin size
    barcode.setRightMargin(0);		       // UPC-E image right margin size
    barcode.setTopMargin(0);		       // UPC-E image top margin size
    barcode.setBottomMargin(0);		       // UPC-E image bottom margin size
    barcode.setRotate(IBarCode.ROTATE_0);      // UPC-E rotation
    
    //Set UPCE human readable text style
    barcode.setDisplayText(true);              // Display human readable text
    barcode.setTextFont(new Font("Arial", Font.PLAIN, 11));
    
    
    //Generate UPC-E barcodes in image GIF format
    barcode.draw("barcode-upce-java.gif");

    //Create UPC-E barcodes in OutputStream object
    barcode.draw("Java java.io.OutputStream Object");
    
    //Draw & Print UPC-E barcodes to Graphics2D object within specified region
    barcode.draw("java.awt.Graphics2D", "java.awt.geom.Rectangle2D");
    
    //Generate UPC-E barcodes & write to byte[] 
    byte[] barcodeInBytes = barcode.drawOutputAsBytes();
    
    //Generate UPC-E barcodes & encode to System.Drawing.Bitmap object 
    BufferedImage barcodeImage = barcode.draw();

• 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); 
          } 
      }
