Java Postnet Barcode Generator - Common Questions



1. How to generate Postnet barcodes in JSP & HTML pages?

  1. Copy "barcoding" folder contents to your Java Servlet container like Tomcat'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=5
  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=0123456789&TYPE=5" border=0 />


2. How to create Postnet barcodes in Java Servlet?

        try {
            Barcode barcode = new Barcode();
            barcode.setSymbology(Barcode.CODE128);
            barcode.setCode("0123456789");

            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 Postnet barcodes in Java Class?
