Java Code-128 Generator

Barcode Code-128 Generation in Java Class, Jasper Reports, iReport, BIRT

Java Barcode offers the most affordable Java barcode generator for barcode Java professionals.

Java Code-128 Introduction

Code 128 is also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, Code 128 Code Set A, Code 128 Code Set B, Code 128 Code Set C, Code 128A, Code 128B, Code 128C

Code 128 is a very effective, high-density symbology which permits the encoding of alphanumeric data. The symbology includes a checksum digit for verification, and the bar code may also be verified character-by-character verifying the parity of each data byte. This symbology has been widely implemented in many applications where a relatively large amount of data must be encoded in a relatively small amount of space. It's specific structure also allows numeric data to be encoded at, effectively, double-density.

Java Barcode Code 128 Generator - How to generate barcode Code-128 in Java Class?

The following Java code illustrates how to generate a barcode in Java class:

BarCode barcode = new BarCode();

// set code 128 barcode properties
barcode.setSymbologyType(BarCode.CODE128);
barcode.setCodeText("CODE128");

// draw and generate barcode to buffered image object
BufferedImage code128Image = barcode.drawBarCode2Image();

Java Barcode Code 128 Generator - How to generate Code-128 barcodes to Java Servlet applicatons?

The following Java code illustrates how to generate a barcode in Java Servlet class:

public class BarcodeServlet extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException
    {
        try {
            BarCode barcode = new BarCode();

            // set barcode properties
            barcode.setSymbologyType(BarCode.CODE128);
            barcode.setCodeText("CODE128");

            // draw and generate barcode to response's ServletOutputStream
            ServletOutputStream servletoutputstream = response.getOutputStream();

            barcode.drawBarCode2Stream(servletoutputstream);

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

Java Barcode Code 128 Generator - How to create Code-128 barcodes through HTTP Request?

Install Java Barcode Generator Servlet application to Tomcat or JBoss, developers need copy the barcode folder to your Tomcat application folder, and restart the Tomcat.
After Tomcat restarted, open your browser and navigate to http://your_tomcat_url:port/barcode/barCode?code-text=CODE128&symbology-type=8
You can also insert barcodes in HTML or JSP pages.

Java Barcode Code 128 Generator - How to draw & print barcode Code-128 to java.awt.Image Object

The following Java source code shows how to generate a barcode in a java.awt.Image object:

private static void demoLinearBarcode() throws Exception
{
    BarCode barcode = new BarCode();

    // set barcode properties
    barcode.setSymbologyType(BarCode.CODE128);
    barcode.setCodeText("CODE128");

    // create image object
    java.awt.image.BufferedImage image = new java.awt.image.BufferedImage(300,300,java.awt.image.BufferedImage.TYPE_BYTE_INDEXED );
    // get graphic context of image
    java.awt.Graphics2D imgGraphics = image.createGraphics();

    // draw barcode to specified location in Rectangle
    barcode.paintBarCode(imgGraphics, new java.awt.Rectangle(0, 0, 300, 300));
}
