How to export .txt file using JReport in java?

Hi all,

private void generateTEXTOutput(JasperPrint jasperPrint,)throws IOException, JRException {

try

{

String fName=filename+".txt";

JRTextExporter export = new JRTextExporter();

export.setParameter(JRExporterParameter.JASPER_PRINT,jasperPrint);

export.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "textfile.txt");

export.exportReport();

}catch (Exception e) {

System.out.println(e);

}

I got this Exception.

"net.sf.jasperreports.engine.JRException:Character or page width must be specified"

How to rectify?

Plz., any one help me....
