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-39 Introduction

Code 39 (also known as "USS Code 39", "Code 3/9", "Code 3 of 9", "USD-3", "Alpha39", "Type 39") is a barcode symbology that can encode uppercase letters (A through Z), digits (0 through 9) and a handful of special characters like the $ sign.

Code 39 is restricted to 44 characters. In Full ASCII Code 39 Symbols 0-9, A-Z, "." ,and "-" are the same as their representations in Code 39. Lower case letters, additional punctuation characters and control characters are represented by sequences of two characters of Code 39.

 

Java Code-39 Generator - Valid Data Scope

Java Code 39 Generator encodes:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  
  
• Uppercase letters (A - Z)
  
  
• - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)

Java Code 39 Extension Generator supports:

• all 128 ASCII characters

 

1. How to generate barcode code 39 in Java class?

   // Create Java Code39 object 
   Code39 barcode = new Code39(); 
   
   // Set Code39 data text to encode
   barcode.setData("CODE39-IN-JAVA"); 
   
   // Generate Code39 barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate Code39 barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-code39.gif"); 
   
   // Generate Code39 barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-code39.jpg"); 
   
   

   
   
   

2. How to generate & encode Code-39 barcodes to EPS?

   // Create Java Code39 object 
   Code39 barcode = new Code39(); 
   
   // Set Code39 data text to encode
   barcode.setData("CREATE CODE39 IN EPS"); 
   
   // Generate Code39 barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-Code39.eps"); 

   
   
   

3. How to create & encode Code 39 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=CODE39
     
     
   • 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=CODE39" />
     
     
   
   
   

4. How to create & print barcode Code 39 image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.Code39; 
   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 { 
               Code39 barcode = new Code39(); 
               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-39 barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   }
