You can download the trial package of Java Barcode library, which includes compiled Java library (Jar file) to generate Code 39 in your Java program, detailed tutorial for generating barcodes in Java, and complete sample Java source code to generate Code 39 in Java class. Downloaded Java barcode generation software allows you to create and print QR Code, Data Matrix, PDF417, Code 128, Code 93, Intelligent Mail, UPC, OneCode and other linear and 2d barcodes.

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? (Complete Java Code 39 Generator Demo Source Code)

   // Build Java Code39 barcode object 
   Code39 barcode = new Code39(); 
   
   // Encode Code39 data
   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 & render 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"); 
   
   // Draw Code39 barcode & paint into EPS image format
   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" />
     
     
   • The above Java codes will not produce any Code 39 image files in your server system, using the above methods to draw Code 39 in JSP, html pages.
   
   
   

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); 
           } 
       } 
   }

8. How to set generated barcode Code 39 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
