Problem generating report JasperReport in JavaFx

When I try to generate a report it turns out that the "The document does not have pages", this is the code with which I generate it.

public class Reporte {    

 public void generarReporte() throws JRException{

    try{

      HashMap parametro = new HashMap();
      parametro.put("","");

      JasperReport reporte = JasperCompileManager.compileReport("report1.jrxml");    

      JasperPrint jasperPrint  = JasperFillManager.fillReport(reporte,parametro);
      JasperViewer view =  new JasperViewer(jasperPrint,false);
      view.setVisible(true);
    } catch(Exception ex){
        System.out.println("Error: "+ex);
    }

 }

}
