I’m looking for a solution to create reports using JasperReports for my application. I found some examples but still could not make it work.
I’m using:
Maven
Vaadin-7
JasperReports-5.51
I’m trying this.
public class Report {
public Report(){
createShowReport();
}
private void createShowReport(){
String reportFile = "reports/report3.jasper";
InputStream file = getClass().getClassLoader().getResourceAsStream(reportFile);
Map parametros = new HashMap();
try {
List<String> lista = new ArrayList<String>();
lista.add("Fernando");
lista.add("Paiva");
JRDataSource dados = new JRBeanCollectionDataSource(lista);
JasperPrint printer = JasperFillManager.fillReport(file, parametros,dados);
JRViewer view = new JRViewer(printer);
} catch (JRException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private Window getWindow(){
Window w = new Window();
w.setSizeFull();
w.setModal(true);
w.setVisible(true);
return w;
}
}
The method getWindow() should return a Window to add my report and show modal.
