lgbuffa,

 

You could possibly:

1. create a little bean (plain old java class - e.g. BarcodeConvert) in your classpath that receives a string and retuns an image.

2. Then, create a variable (e.g. variable bcdConverter) to hold a reference to that bean (e.g initial value: new BarcodeConvert() ).

3. Finally, wherever you need this barcode inserted, put $V{bcdConverter}.toImage("Your barcode string")

 

I believe you could accomplish the same if you place the code in the referenced message in a scriptlet, attach the scriptlet to your report, and call the scriptlet method wherever you need the barcode inserted...

 

I hope this helps.

 

Alex

Thanks for help, but I solved the problem using a scriptlet.There's the code:

 

import java.awt.Color;

import java.awt.Image;

 

import com.lowagie.text.pdf.BarcodeInter25;

 

import dori.jasper.engine.JRDefaultScriptlet;

import dori.jasper.engine.JRScriptletException;

 

public class BarCodeScriptlet extends JRDefaultScriptlet {

 

public void afterReportInit() throws JRScriptletException {

 

Image image25;

BarcodeInter25 code25 = new BarcodeInter25();

code25.setCode((String)super.getFieldValue("BARCODE"));

code25.setBarHeight(60);

image25 = code25.createAwtImage(Color.black, Color.white);

super.setVariableValue("CODE", image25);

 

}

 

}
