That's how I use it not to have Serialisation problem :
JRResource resourcePDF = new
JRConcreteResource<PdfResourceHandler>(reportFile, new PdfResourceHandler())
{
public JRDataSource getReportDataSource() {
//retrieve you data
//...
return new JRBeanCollectionDataSource(yourCollection);
}
public Map<String, Object> getReportParameters() {
Map<String, Object> params = new HashMap<String, Object>();
//set your parameters
params.put("base_path",
WebApplication.get().getServletContext().getRealPath(""));
return params;
}
};
Hope this help.
Gabriel.
