Barcode EAN-8 Introduction

EAN-8 is a barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.

Java EAN-8 Generator - Valid Data Scope

Java EAN 8 Generator encodes:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

1. How to generate barcode EAN-8 in Java class? (Complete Java EAN-8 Generator Demo Source Code)

   // Create Java EAN8 object 
   EAN8 barcode = new EAN8(); 
   
   // Set EAN8 data text to encode. It must be 7 digits, without last checksum digit.
   barcode.setData("1234567"); 
   
   // Generate EAN8 barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate EAN8 barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-ean8.gif"); 
   
   // Generate EAN8 barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-ean8.jpg"); 
   
   

   
   
   

2. How to generate & encode EAN-8 barcodes to EPS?

   // Create Java EAN8 object 
   EAN8 barcode = new EAN8(); 
   
   // Set EAN8 data text to encode. It must be 7 digits, without last checksum digit.
   barcode.setData("1234567"); 
   
   // Generate EAN8 barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-ean8.eps"); 

   
   
   

3. How to create & encode EAN-8 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=1234567&TYPE=EAN8
     
     
   • 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=1234567&TYPE=EAN8"/>
     
     
   
   
   

4. How to create & print barcode EAN-8 image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.EAN8; 
   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 { 
               EAN8 barcode = new EAN8(); 
               barcode.setData("1234567"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
               
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate EAN8 barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   }

7. How to generate & print barcode EAN-8 image in Eclipse BIRT?

   
   
   You can stream barcodes into your BIRT reports using Java Barcode Generator.
   
   However we recommend you use our BIRT Barcode Generator Plugin to generate and print EAN 8 barcodes in your BIRT reports.
   
   

8. How to set generated barcode EAN-8 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
