Demo Code to Create GS1-128 in Java

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. GS1-128 is also called EAN-128, UCC-128, USS-128, GS1 128, UCC.EAN-128, GTIN-128, UCC-12, EAN/UCC-13, EAN/UCC-14.

Java Barcode EAN-128 / GS1-128 Generator prints:

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

The GS1-128 barcode above encodes a production date as Jan 01, 2009

1. How to generate EAN-128 / GS1-128 barcodes in JSP & HTML pages?

1. Copy "barcoding" folder contents to your Java Servlet container like Tomcat or JBoss's applications folder
2. Restart your Java Servlet container
3. Open your web browser like IE, Firefox, and navigate to http://localhost:8080/barcoding/linear?DATA=(11)090101&TYPE=15
4. To generate barcode images in JSP or HTML pages, insert the following html img tag code:
   <img src="http://localhost:8080/barcoding/linear?DATA=(11)090101&TYPE=15" border=0 />

2. How to create EAN-128 / GS1-128 barcodes in Java Servlet?

        try {
            Barcode barcode = new Barcode();
            barcode.setSymbology(Barcode.EAN128);
            barcode.setCode("(11)090101");

            response.setContentType("image/jpeg");
            response.setHeader("Pragma", "no-cache");
            response.setHeader("Cache-Control", "no-cache");
            response.setDateHeader("Expires", 0);
            ServletOutputStream servletoutputstream = response.getOutputStream();

            barcode.drawOnStream(servletoutputstream);

        } catch (Exception e) {
            throw new ServletException(e);
        }        

3. How to encode Application Identifier (AI) to compatible with GS1 128 in Java Class?

You need put parentheses around AIs. View the details in the following Java code:

        Barcode barcode = new Barcode();
        barcode.setSymbology(Barcode.EAN128);
        // The first AI 11 means production date is Jan 01, 2009
        // The second AI 13 means packaging date is Feb 01, 2009
        barcode.setCode("(11)090101(13)090201");
        barcode.drawImage2File("C://ean128.gif");

4. How to generate EAN-128 / GS1-128 barcodes in Java Class?

        Barcode barcode = new Barcode();

        barcode.setCode("(11)090101");
        barcode.drawImage2File("C://ean128.gif");

5. How to draw EAN-128 / GS1-128 barcodes to image files?

        Barcode barcode = new Barcode();
        barcode.setSymbology(Barcode.EAN128);
