detail is blank when using API

2003-03-25 01:50

I use IReport to make simple report with static text detail, and compile to xls successfully in IReport.

But using API, the part of detail is blank! (the header and footer display normally)

The source code like below:

 

System.setProperty ("org.xml.sax.driver","org.apache.xerces.parsers.SAXParser");

try

{

JasperReport jasperReport = JasperCompileManager.compileReport ("Jasper.xml");

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,null,(JRDataSource) null);

JRXlsExporter exporter = new JRXlsExporter();

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "Jasper.xls");

exporter.exportReport();

}

catch( Exception e )

{

System.out.println( "make report error" );

System.out.println(e);

}

I need to pass to method 'JasperManager.fillReportToFile' only report design file and parameters, no connections or resultsets ('null' parameters does not work).

Can anybody help me?

 

Thanks

Hi,

 

Provide the fill method with the most basic data

source available, which is the JREmptyDataSource.

 

You can find this in the samples.

 

JasperManager.fillReportToFile(

fileName,

parameters,

new JREmptyDataSource()

);

 

Good luck!

Teodor
