Problema Netbean 7 e IReprot

Saludos, he intentado utilizar el Plugin de Ireport en Netbeans 7 y al instalarlo me genera error. Por tal motivo he decidido generar el reporte aparte con Ireport y llamarlo desde java.

Parar ello utiliszo los import
import java.util.HashMap;
import javax.swing.JOptionPane;
import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.util.JRLoader;
import net.sf.jasperreports.view.JasperViewer;

y al presionar un boton llamo al reporte

String RutaInforme = "Reportes\\ReporteHematologia.jasper";
HashMap parametro = new HashMap();

try {
JasperPrint informe = JasperFillManager.fillReport(RutaInforme, parametro, new JREmptyDataSource());
JOptionPane.showMessageDialog(null,"2");
JasperViewer jviewer = new JasperViewer(informe,false);
jviewer.setTitle("Reporte");
jviewer.setVisible(true);

} catch (JRException e) {

}

el programa compila bien pero al ejecutarlo ma arroja el siguiente error
