JasperReports always opening the same report ?

I’m trying create a report using JasperReports to my application. What happens is when I do some change at JasperReport does not update in my application. I tried refresh my project, refresh my browser and always displayed report without changes

I’m trying this

[code]
public class ImprimeListaChamadaReport {
private Turma turma;
private final String pathJasper = “br/com/webapp/reports/jasper/ListaDeChamadas.jasper”;

public ImprimeListaChamadaReport(Turma t){
    this.turma = t;
    createReport();
}

private void createReport(){
    final Map map = new HashMap();                
    //map.put("TURMA", turma.getTurma() + "/" + new SimpleDateFormat("yyyy").format(turma.getAno()));        
    final JRDataSource ds = new JRBeanCollectionDataSource(turma.getMatriculas());
    
    StreamResource.StreamSource source = new StreamResource.StreamSource() {
        public InputStream getStream() {
            byte[] b = null;
            
            try {                    
                b = JasperRunManager.runReportToPdf(getClass().getClassLoader().getResourceAsStream(pathJasper), map, ds);
            } catch (JRException ex) {
               ex.printStackTrace();
            }
            return new ByteArrayInputStream(b);
        }
    };
          
    
    StreamResource resource = new StreamResource(source, "ListaDeChamadas.pdf");
    resource.setMIMEType("application/pdf");              
    
    
    Embedded e = new Embedded("", resource);
    e.setSizeFull();
    e.setMimeType("application/pdf");
    e.setType(Embedded.TYPE_BROWSER);       
    
    ReportWindow w = new ReportWindow("Lista de chamada", e);
    UI.getCurrent().addWindow(w);       
}

}
[/code]I posted the images. I did change “Hellooooo” and when I do display doesn’t changed.

Any idea ?
