Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.

 

Barcode Code-128 Introduction

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 Generator - Valid Data Scope

Java Code 128 Generator encodes:

• 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 barcode code 128 in Java class?

   // Create Java Code128 object 
   Code128 barcode = new Code128(); 
   
   // Set Code128 data text to encode
   barcode.setData("CODE128-IN-JAVA"); 
   
   // Generate Code128 barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate Code128 barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-code128.gif"); 
   
   // Generate Code128 barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-code128.jpg"); 
   
   

   
   
   

2. How to generate & encode Code-128 barcodes to EPS?

   // Create Java Code128 object 
   Code128 barcode = new Code128(); 
   
   // Set Code128 data text to encode
   barcode.setData("Create Code128 in EPS"); 
   
   // Generate Code128 barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-code128.eps"); 

   
   
   

3. How to create & encode Code 128 image in html or jsp pages?

   
   
   
   • Under demo package, copy barcode folder and its contents to your tomcat.
     
     
   • Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE128
     
     
   • To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
     For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=0123456789&TYPE=CODE128" />
     
     
   
   
   

4. How to create & print barcode Code 128 image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.Code128; 
   import javax.servlet.http.HttpServlet; 
   import javax.servlet.http.HttpServletRequest; 
   import javax.servlet.http.HttpServletResponse; 
   import javax.servlet.ServletException; 
   import javax.servlet.ServletOutputStream; 
      
   public class BarcodeServlet extends HttpServlet 
   { 
       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
       { 
           try { 
               Code128 barcode = new Code128(); 
               barcode.setData("0123456789"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
                 
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate Code-128 barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   }

8. How to set generated barcode Code 128 image width and height?

   1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values.
   
   or
   
   2) You can set X (bar module width) and Y (bar module height) values
