alguem sabe como resolver?
abaixo segue meu código:
try {
ClassConecta.conectajTorre();
} catch (SQLException ex) {
Logger.getLogger(jFPrincipal.class.getName()).log(Level.SEVERE, null, ex);
}
String caminhoRelJasper = "Relatorios/RUltimasFerias.jasper";
ResultSet rs = null;
try {
JRResultSetDataSource ds = new JRResultSetDataSource(rs);
URL arquivo = getClass().getResource(caminhoRelJasper);
if (arquivo == null)
JOptionPane.showMessageDialog(null,"Arquivo jasper não encontrado");
JasperReport report;
try {
report = JasperManager.loadReport(arquivo.openStream());
JasperPrint jasperPrint = JasperFillManager.fillReport(report, new HashMap(), ds);
JasperViewer jrviewer = new JasperViewer(jasperPrint, false);
jrviewer.setVisible(true);
} catch (JRException ex) {
Logger.getLogger(jFPessoas.class.getName()).log(Level.SEVERE, null, ex);
JOptionPane.showMessageDialog(null, "Erro ao gerar relatório", "Mensagem do sistema\n"+ex, JOptionPane.ERROR_MESSAGE);
}
} catch (IOException ex) {
Logger.getLogger(jFPessoas.class.getName()).log(Level.SEVERE, null, ex);
JOptionPane.showMessageDialog(null, "Erro ao gerar relatório\n"+ex, "Mensagem do sistema", JOptionPane.ERROR_MESSAGE);
}
Desde já agradeço a quem puder ajudar.
