Java Code-128 Generator

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

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.

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

22       private static void testLinear() throws Exception 
23       { 
24           Linear barcode = new Linear(); 
25    
26           // set barcode properties 
27           barcode.setType(Linear.CODE128); 
28           barcode.setData("1234567890"); 
29    
30           // draw and generate barcode to specified file 
31           barcode.draw("C:\\Code128.gif"); 
32       } 

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

11   public class BarcodeServlet extends HttpServlet { 
12       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
13       { 
14           try { 
15               Linear barcode = new Linear(); 
16    
17               // set barcode properties 
18               barcode.setType(Linear.CODE128); 
19               barcode.setData("1234567890"); 
20    
21               // draw and generate barcode to response's ServletOutputStream 
22               ServletOutputStream servletoutputstream = response.getOutputStream(); 
23    
24               barcode.draw(servletoutputstream); 
25    
26           } catch (Exception e) { 
27               throw new ServletException(e); 
28           } 
29       } 
30   } 
31   

View BarcodeServlet.java source code

1. 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.
   
   
2. After Tomcat restarted, open your browser and navigate to http://your_tomcat_url:port/barcode/linear?data=12345678&type=8
   
   
3. You can also insert barcodes in HTML or JSP pages.

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

21    
22       private static void testLinear() throws Exception 
23       { 
24           Linear barcode = new Linear(); 
25            
26           // set barcode properties 
27           barcode.setType(Linear.CODE128); 
28           barcode.setData("1234567890"); 
29            
30           // create image object 
31           java.awt.image.BufferedImage image = new java.awt.image.BufferedImage(300,300,java.awt.image.BufferedImage.TYPE_BYTE_INDEXED ); 
32           // get graphic context of image 
33           java.awt.Graphics2D imgGraphics = image.createGraphics(); 
34    
35           // draw barcode to specified location in Rectangle 
36           barcode.draw(imgGraphics, new java.awt.Rectangle(0, 0, 300, 300)); 
37       }
