Java Barcode UPC-E Generator Introduction

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.

 

Barcode UPC-E Introduction

UPC-E 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

Java UPC-E Generation FAQ?

  1. How to generate barcode UPC-E in Java class? (Complete Java UPC-E Generator Demo Source Code)

    // Create Java UPCE object 
    UPCE barcode = new UPCE(); 
    
    // Set UPC-E data text to encode. It must be 6 digits, without the first number system and the last checksum digit.
    barcode.setData("123456"); 
    
    // Generate UPC-E barcode & print into Graphics2D object
    barcode.drawBarcode("Java Graphics2D object"); 
    
    // Generate UPC-E barcode & encode into GIF format
    barcode.drawBarcode("C://barcode-upce.gif"); 
    
    // Generate UPC-E barcode & encode into JPEG format
    barcode.drawBarcode("C://barcode-upce.jpg"); 
    
    


  2. How to generate & encode UPC-E barcodes to EPS?

    // Create Java UPCE object 
    UPCE barcode = new UPCE(); 
    
    // Set UPC-E data text to encode. It must be 6 digits, without the first number system and the last checksum digit.
    barcode.setData("123456"); 
    
    // Generate UPCE barcode & encode into EPS
    barcode.drawBarcode2EPS("C://barcode-upce.eps"); 


  3. How to create & encode UPC-E 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=123456&TYPE=UPCE

    • 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=123456&TYPE=UPCE"/>

                barcode.setData("123456"); 
                     
                ServletOutputStream servletoutputstream = response.getOutputStream(); 
                  
                response.setContentType("image/jpeg"); 
                response.setHeader("Pragma", "no-cache"); 
                response.setHeader("Cache-Control", "no-cache"); 
                response.setDateHeader("Expires", 0); 
               
                // Generate UPCE barcode & output to ServletOutputStream
                barcode.drawBarcode(servletoutputstream); 
          
            } catch (Exception e) { 
                throw new ServletException(e); 
            } 
        } 
    }

  7. How to generate & print barcode UPC-E image in Eclipse BIRT?



    You can stream barcodes into your BIRT reports using Java Barcode Generator.

    However we recommend you use our BIRT Barcode Generator Plugin to generate and print UPC E barcodes in your BIRT reports.

  8. How to set generated barcode UPC-E image width and height?

    1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values.

    or

    2) You can set X (bar module width) and Y (bar module height) values
