Java Barcode Code 93 Generator Introduction

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.

 

Code-93 Introduction

Code 93 is a barcode symbology designed in 1982 by Intermec to provide a higher density and data security enhancement to Code 39. It is an alphanumeric, variable length symbology. Code 93 is used primarily by Canada Post to encode supplementary delivery information. Every symbol includes two check characters.

 

Java Code-93 Generator - Valid Data Scope

Java Code 93 Generator encodes:

  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

  • uppercase letters (A through Z)

  • - (Dash), . (Point), $ (Dollar), / (Slash), + (Plus), % (Percentage), (Space)



 

Java Code 93 Barcode Generation FAQ?

  1. How to generate barcode Code 93 in Java class? (Complete Java Code 93 Generator Demo Source Code)

    // Create Java Code93 object 
    Code93 barcode = new Code93(); 
    
    // Set Code93 data text to encode
    barcode.setData("CODE93-IN-JAVA"); 
    
    // Generate Code93 barcode & print into Graphics2D object
    barcode.drawBarcode("Java Graphics2D object"); 
    
    // Generate Code93 barcode & encode into GIF format
    barcode.drawBarcode("C://barcode-code93.gif"); 
    
    // Generate Code93 barcode & encode into JPEG format
    barcode.drawBarcode("C://barcode-code93.jpg"); 
    
    


  2. How to generate & encode Code-93 barcodes to EPS?

    // Create Java Code93 object 
    Code93 barcode = new Code93(); 
    
    // Set Code93 data text to encode
    barcode.setData("CREATE-CODE93-IN-EPS"); 
    
    // Generate Code93 barcode & encode into EPS
    barcode.drawBarcode2EPS("C://barcode-code93.eps"); 


  3. How to create & encode Code-93 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=code93

    • 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=code93"/>
