[Error in integrating JasperReports with Hibernate]

Hi,

 

I am getting Error while integrating Jasper reports with Hibernate...

 

 

 

I have the following code..

 

 

List list = s.getReportsData ("shantanu9@xyz.com","AnujTest","Subscription",stamp,estamp);

 

JasperReport jasperReport;

JasperPrint jasperPrint;

 

Map parameters = new HashMap();

 

JasperDesign jasperDesign = JRXmlLoader.load

("C:/eclipse/workspace/anuj/com/test/jasperreports_demo.jrxml");

 

jasperReport = JasperManager.compileReport(jasperDesign);

 

JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);

jasperPrint = JasperManager.fillReport(jasperReport, parameters, ds);

 

JasperManager.printReportToPdfFile(jasperPrint, "C:/eclipse/workspace/anuj/com/test/Report.pdf");

 

 

 

The list which my Business Layer is returning consists of a Transaction table rows in which each coulmn represents Other class for eg one column represents SaasUserImpl.class. After I pass the list to Jasper reprt's xml file i get Class Cast exception that class cast exception SaasUserImpl.. n if I type cast it into my known class by using object it says invalid report format...

 

 

 

<reportElement mode="Opaque" backcolor= "#ffdd99" positionType="Float" x="132" y="12" width="80" height="20"/>

 

<textElement textAlignment="Center"/>

 

<textFieldExpression class="java.lang.String"><![CDATA[$F{userId}_getLoginName()]]></textFieldExpression>

 

</textField>

 

 

Kindly let me know is there any way i can retrieve my class objects in the xml file....

 

 

 

regards,

 

Anuj
