Hi,
I have the following code:
InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml");
HashMap<String, String> parameters = new HashMap<String, String>();
parameters.put("StringParameterName", "show me");
try {
JasperReport report = JasperCompileManager.compileReport(reportFile);
JasperPrint print = JasperFillManager.fillReport(report, parameters);
return JasperExportManager.exportReportToPdf(print);
} catch (JRException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
And the test.jrxml looks like this (I generated part of it with the iReport, the only thing I did was to remove the language="groovy" attribute):
<?xml version="1.
0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="test" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

<textElement/>
<textFieldExpression class="java.lang.String"><![CDATA[$P{StringParameterName}]]></textFieldExpression>
</textField>
</band>

<columnFooter>

</columnFooter>
<pageFooter>
<band height="54" splitType="Stretch"/>
</pageFooter>
<summary>
<band height="42" splitType="Stretch"/>
</summary>
</jasperReport>
As a result I always get a blank pdf file. What could be the reason?
