Embedding a barcode

HOW-TO APPLICATION DEVELOPER STAND: JUL 2026 GILT FUER NUCLOS 4.2026.X

Barcodes in JasperReports

For barcodes the palette offers two libraries under Barcode: barcode4j and barbecue.

Simple embedding

1. Drag the barcode component from the palette onto the canvas.
2. Choose the library and barcode type, confirm with Finish.
3. Enter the value/string in the properties (some types accept only a fixed length).

Adding the barcode component.

Embedding via the image object

For more control (e.g. font/size of the text below the barcode) embed the barcode via an image object. Create a Java library project with a class and add it to the class path of the bundled jasperreports-6.17.0.jar. Example (EAN13, 13‑digit):

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package org.barcodeself;
import java.awt.Font;
import net.sourceforge.barbecue.Barcode;
import net.sourceforge.barbecue.BarcodeException;
import net.sourceforge.barbecue.BarcodeFactory;
import net.sourceforge.barbecue.BarcodeImageHandler;
import net.sourceforge.barbecue.output.OutputException;
/**
 *
 * @author rufus
 */
public class EAN13 {
    public static java.awt.Image createEANdreiZehn(String c) throws OutputException, BarcodeException{
       if(c.isEmpty() || c.equals("")|| c.length() != 13){
           c = "000000000000";
       }
       else{
           c = c.substring(0, 12);
       }
       Barcode b = BarcodeFactory.createEAN13(c);
       Font f = new Font("SanSerif", Font.BOLD, 12);
       b.setFont(f);
       return BarcodeImageHandler.getImage(b);
    }
}

In the designer place an image element and set:

Image Expression = org.barcodeself.EAN13.createEANdreiZehn("12-digit")
Expression Class = java.awt.Image

EAN13 note

The EAN13 has 13 digits, the last being a check digit appended during generation – so only 12 digits may be passed to the generator. An externally generated EAN13 may need to be shortened in the data source (Postgres: substring(ap."strean" from 1 for 12)).
