Blank report

[pstanton]

Hi All,

 

I've used jasper on a couple of projects in the past, and think I've set this project up correctly, yet the simplest report is returning a blank page!

 

Here's my report jrxml:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN"
	"http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

<jasperReport name="TestReport" pageWidth="595" pageHeight="842" columnWidth="555"
		leftMargin="20" rightMargin="20" topMargin="30" bottomMargin="30">
 <title>
  <band height="782">
   <staticText>
    <reportElement x="1" y="1" width="220" height="40"/>
    <textElement textAlignment="Center"/>
     <text><![CDATA[something in a report?]]></text>
   </staticText>
   </band>
  </title>
</jasperReport>

 

and my java to fill it (it compiles without error via the ant task):

 

Code:

[code]JasperPrint print = JasperFillManager.fillReport(reportDir + "TestReport.jasper", new HashMap()); InputStream in = new ByteArrayInputStream(JasperExportManager.exportReportToPdf(print)); OutputStream out = new FileOutputStream(new File("C:/test.pdf"«»)); org.apache.commons.io.IOUtils.copy(in, out); in.close(); out.flush(); out.close();

 

Why would this return a blank pdf?

 

Thanks.

missing JREmptyDataSource. had to change

 

 

Code:

JasperFillManager.fillReport(reportDir + "TestReport.jasper", new HashMap());

 

to

 

Code:

[code]JasperFillManager.fillReport(reportDir + "TestReport.jasper", new HashMap(), new JREmptyDataSource());

thx, where do i set that option?

[lucianc]

whenNoDataType is an attribute of the jasperReport (root) JRXML element (see the JRXML reference).

 

If you use iReport, it would be in the Report Properties dialog.

 

HTH,
