e o Código que carrega o relatório é esse:
private void btnRltrTodosEquipBLActionPerformed(java.awt.event.ActionEvent evt) {
conex.conectar();
try {
URL arquivo = getClass().getResource("/relatorios/TodosEquipBelaVista.jasper");
JasperReport jasperReport = (JasperReport) JRLoader.loadObject( arquivo ); // essa é a linha 184
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conex.con);
JasperViewer view = new JasperViewer(jasperPrint,false);
view.setVisible(true);
} catch (JRException ex) {
System.out.println("Error: "+ex);
}
conex.desconetar();
}
Desde já agradeço
