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-A Introduction

UPC-A is also known as Universal Product Code version A, UPC-A Supplement 5/Five-digit Add-On, UPC-A Supplement 2/Two-digit Add-On, UPC-A+5, UPC-A+2, UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12

 

Java UPC-A Generator - Valid Data Scope

Java UPC-A Generator encodes:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

 

1. How to generate barcode UPC-A in Java class?

   // Create Java UPCA object 
   UPCA barcode = new UPCA(); 
   
   // Set UPCA data text to encode. It must be 11 digits, without the first number system and the last checksum digit.
   barcode.setData("12345678912"); 
   
   // Generate UPCA barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate UPCA barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-upca.gif"); 
   
   // Generate UPCA barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-upca.jpg"); 
   
   

   
   
   

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

   // UPCA Java UPCA object 
   UPCA barcode = new UPCA(); 
   
   // Set UPCA data text to encode. It must be 11 digits, without the first number system and the last checksum digit.
   barcode.setData("12345678912"); 
   
   // Generate UPCA barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-upca.eps"); 

   
   
   

3. How to create & encode UPC-A 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=12345678912&TYPE=UPCA
     
     
   • 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=12345678912&TYPE=UPCA" />
     
     
   
   
   

4. How to create & print barcode UPC-A image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.UPCA; 
   import javax.servlet.http.HttpServlet; 
   import javax.servlet.http.HttpServletRequest; 
   import javax.servlet.http.HttpServletResponse; 
   import javax.servlet.ServletException; 
   import javax.servlet.ServletOutputStream; 
      
   public class BarcodeServlet extends HttpServlet 
   { 
       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
       { 
           try { 
               UPCA barcode = new UPCA(); 
               barcode.setData("12345678912"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
                 
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate UPCA barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   }

8. How to set generated barcode UPC-A 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
