GS1 128 / EAN 128 Introduction

GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.

Java GS1 128 / EAN 128 Generator - Valid Data Scope

Java EAN 128/GS1 128 Generator encodes:

• all 128 characters of ASCII
  
  
• values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

GS1 Function Code 1 (FNC1) and the Application Identifier (AI)

OnBarcode Java Barcode Generator allows easily to add application identifiers in GS1 128 / EAN 128, by add parentheses to AIs.

For example, to encode AI (00), with data 350123451234567894, with second AI (21), with data 01234567, you need pass string "(00)350123451234567894(21)01234567" to barcode data property

	        EAN128 barcode = new EAN128(); 
	        
	        barcode.setData("(00)350123451234567894(21)01234567"); 
	    
	        ean128.Format = ImageFormat.Gif;
	        ean128.drawBarcode("java-ean128.gif");

1. How to generate barcode GS1 128 in Java class? (Complete Java GS1 128 Generator Demo Source Code)

   // Create Java EAN128 object 
   EAN128 barcode = new EAN128(); 
   
   // Set EAN128 data text to encode
   barcode.setData("(00)350123451234567894"); 
   
   // Generate EAN128 barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate EAN128 barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-ean128.gif"); 
   
   // Generate EAN128 barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-ean128.jpg"); 
   
   

   
   
   

2. How to generate & encode GS1-128/EAN-128 barcodes to EPS?

   // Create Java EAN128 object 
   EAN128 barcode = new EAN128(); 
   
   // Set EAN128 data text to encode
   barcode.setData("(00)350123451234567894"); 
   
   // Generate EAN128 barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-ean128.eps"); 

   
   
   

3. How to create & encode GS1-128/EAN-128 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=(00)350123451234567894&TYPE=EAN128
     
     
   • 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=(00)350123451234567894&TYPE=EAN128" />
     
     
   
   
   

4. How to create & print barcode GS1-128/EAN-128 image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode;

       { 
           try { 
               EAN128 barcode = new EAN128(); 
               barcode.setData("(00)350123451234567894"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
                 
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate EAN128 barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       }
