Hi,

I would like to pass as a parameter to my .jrxml an arbitrary object of my domain, e.g a Person.

InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml");
HashMap<String, Person> parameters = new HashMap<String, Person>();
parameters.put("person", new Person("John", "Doe"));
...
JasperReport report = JasperCompileManager.compileReport(reportFile);
JasperPrint print = JasperFillManager.fillReport(report, parameters, new JREmptyDataSource());
return JasperExportManager.exportReportToPdf(print);

And on the .jrxml do something like:

<?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">
 <property name="ireport.zoom" value="1.0"/>
 <property name="ireport.x" value="0"/>
 <property name="ireport.y" value="0"/>
 <parameter name="PERSON" isForPrompting="false" class="myApp.domain.person"/>
 <background>
  <band splitType="Stretch"/>
 </background>
 <title>
  <band height="20">
       <staticText>
         <reportElement x="180" y="0" width="200" height="20"/>
         <text><![CDATA[$P{PERSON.lastName}]]></text>
       </staticText>
     </band>
 </title>
...

Is something like this possible? Where can I find more complex tutorials that show more than just passing a java.lang.String?

Thanks
