How to create Bar Code in java (using aspose and itext) ?

Using aspose API.

For creating a Bar Code is very simple in java using aspose apis. We can use “aspose-barcode-5.4.2-jdk15.jar” for this.





Step 1: Create “BarCode.java” as a servlet. Within this class we have to create BarCodeBuilder object and set certain property to it and we will get the bar code image and later we will add this image as response in form of any image format and send it to the browser.

BarCode.java

package p1;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.aspose.barcode.*;
import java.awt.image.BufferedImage;
import java.io.OutputStream;
import javax.imageio.ImageIO;

public class BarCode extends HttpServlet
{
   public void doGet(
        HttpServletRequest request,
        HttpServletResponse response)
        throws IOException, ServletException
    {
        System.out.println("bar code servlet");
        // Create BarCodeBuilder instance
        BarCodeBuilder b = new BarCodeBuilder();
        // Set up symboogy
        b.setSymbologyType(Symbology.Code128);
        // Set up code text
        b.setCodeText("12345678");
        
        b.setCodeLocation(CodeLocation.None);
        
        // Render barcode
        BufferedImage image = b.getBarCodeImage();

        response.setContentType("image/png");
        OutputStream outputStream = response.getOutputStream();
        ImageIO.write(image, "png", outputStream);
        outputStream.close();
    }

}

Step 2: Add the entry into web.xml.

<?xml version="1.0" encoding="UTF-8"?>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

Step 3: Create jsp page. And use <img src="http://localhost:8084/AllPOC/BarCode" /> for rendering the Bar code at appropriate page.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

    <body>
        This is a barcode image generated by servlet:
        <br />
        <img src="http://localhost:8084/AllPOC/BarCode" />
    </body>
</html>

Note: We can customize the Bar code as per our requirement. 

A) Bar Code Alignment. 
1- If you don’t want to show the code as part of barcode use b.setCodeLocation(CodeLocation.None); or b.setCodeLocation(2);
2- If you want to display the code top of bar code use b.setCodeLocation(CodeLocation.Above); or b.setCodeLocation(0);
3- If you want to display the code bottom of bar code use b.setCodeLocation(CodeLocation.Below); or b.setCodeLocation(1);

B) Bar Code pattern . 
There are so many style for bar code you can change the Symbology to obtain the different - different style.  There are 48 type of Bar code available you just use any one of them using-

b.setSymbologyType(Symbology.Code128); 

Instead of Code128 you can choose any one from below. 
1-    Codabar
2-    Code11
3-    Code39Standard 
4-    Code39Extended 
5-    Code93Standard 
6-    Code93Extended 
7-    Code128

Some of the code and related bar code is given below-



Store the the Bar Code into PDF.

If you want to store BarCode in pdf file use below program using itext apis using  “itext-1.3.jar”. In this program you need not to use aspose apis.

import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.Barcode128;
import com.lowagie.text.pdf.PdfWriter;

public class BarCode128 {

    public static void main(String[] args) throws FileNotFoundException, DocumentException {

        Document document = new Document(new Rectangle(PageSize.A4));
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("h:/a2z_BarCode_128.pdf"));

        document.open();
        document.add(new Paragraph("Generated Bar Code"));

        Barcode128 code128 = new Barcode128();
        code128.setGenerateChecksum(true);
        code128.setCode("ram123");

        document.add(code128.createImageWithBarcode(writer.getDirectContent(), null, null));
        document.close();

        System.out.println("Bar code generated.");
    }
}

You will get Generated PDF with Bar Code


 Note : You can verified your generated bar code whether it’s correct or not using below url :
           http://www.onlinebarcodereader.com/

 open this url browser you bar code and click on send file you will get you code and bar code format name as well



Answer 2: Using itext apis ?

public class BarcodeServlet extends HttpServlet {

    
    public void service(HttpServletRequest request, HttpServletResponse response) throws IOException {

        System.out.println(1);
        try {

            code39ext.setCode("Testing Text");
            code39ext.setStartStopText(false);
            code39ext.setExtended(true);
            java.awt.Image rawImage = code39ext.createAwtImage(Color.BLACK, Color.WHITE);
            BufferedImage outImage = new BufferedImage(rawImage.getWidth(null), rawImage.getHeight(null), BufferedImage.TYPE_INT_RGB);
            outImage.getGraphics().drawImage(rawImage, 0, 0, null);
            ByteArrayOutputStream bytesOut = new ByteArrayOutputStream();
            ImageIO.write(outImage, "png", bytesOut);
            bytesOut.flush();
            pngImageData = bytesOut.toByteArray();

        } catch (Exception e) {
            e.printStackTrace();

        if (pngImageData != null) {
            response.setContentLength(pngImageData.length);
            response.setContentType("image/png");
            OutputStream out = response.getOutputStream();
            out.write(pngImageData);
            out.flush();
            out.close();
        } else {
// Add code to display noimage
            response.sendRedirect("/images/nophoto.jpg");
        }
    }
}

Step 2: Add entries into web.xml.

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

Step 3: Create BarCodeCreator.jsp

        This is a barcode image generated by servlet:
        <br />
        <img src="http://localhost:8084/AllPOC/BarcodeServlet" />
    </body>
</html>

The output of this program is same as above one.

Note : The itext apis are open source.
