Java Barcode Code 39 Generator - Java Class Implementation

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       }

Java Barcode Code 39 Generator - Java Servlet Implementation

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   }

Java Barcode Code 39 Generator - HTTP Request Implementation

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/linear?data=12345678&type=8
You can also insert barcodes in HTML or JSP pages.

Java Barcode Code 39 Generator - java.awt.Image Object Implementation

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       }
