Barcodes in JasperReports
For barcodes the palette offers two libraries under Barcode: barcode4j and barbecue.
Simple embedding
- Drag the barcode component from the palette onto the canvas.
- Choose the library and barcode type, confirm with Finish.
- 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):
| Codeblock |
|---|
|
/*
* 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:
| Codeblock |
|---|
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)).
Barcode in the report.
