Java Code-128 Generator

Create Barcode Code-128 in Java Class, Servlet, Jasper Reports, iReport & BIRT

Code 128 is a very high-density barcode symbology. (A special version of it called GS1-128 is used extensively world wide in shipping and packaging industries.) It is used for alphanumeric or numeric-only barcodes.

Java Code-128 prints:

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

1. How to generate Code-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=0123456789&TYPE=11
4. To generate Code128 barcode images in JSP or HTML pages, insert the following html img tag code:
   <img src="http://localhost:8080/barcoding/linear?DATA=0123456789&TYPE=11" border=0 />

2. How to create Code-128 barcodes in Java Servlet?

        try {
            Barcode barcode = new Barcode();
            barcode.setSymbology(Barcode.CODE128);
            barcode.setCode("JAVA-CODE128-BARCODES");

            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 generate Code-128 barcodes in Java Class?

        Barcode barcode = new Barcode();
        barcode.setSymbology(Barcode.CODE128);
        barcode.setCode("CODE128-BARCODES");
        barcode.drawImage2File("C://code128.gif");

4. How to draw Code-128 barcodes to image files?

        Barcode barcode = new Barcode();
        barcode.setSymbology(Barcode.CODE128);
        barcode.setCode("CODE128-BARCODES-IN-JAVA");
        barcode.drawImage2File("C://code128.gif");

5. How to draw & print Code-128 barcodes to Java image objects or stream objects?

        Barcode barcode = new Barcode();
        barcode.setSymbology(Barcode.CODE128);
        barcode.setCode("JAVA-CODE128");
        barcode.drawOnGraphics("Graphics2D object");
        
        barcode.drawOnStream("OutputStream object");
