Resolvi da seguinte forma:
[code] private void jButtonImprimirRelGeralActionPerformed(java.awt.event.ActionEvent evt) {
try {
visualizarRelatorio();
} catch (ClassNotFoundException ex) {
Logger.getLogger(FormRelGeral.class.getName()).log(Level.SEVERE, null, ex);
} catch (SQLException ex) {
Logger.getLogger(FormRelGeral.class.getName()).log(Level.SEVERE, null, ex);
} catch (JRException ex) {
Logger.getLogger(FormRelGeral.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void visualizarRelatorio() throws ClassNotFoundException, SQLException, JRException {
JasperPrint relatorio = null;
JasperReport jasperReport = null;
Class.forName(driver);
Connection con = (Connection) DriverManager.getConnection(url, login, pwd);
Statement stm = (Statement) con.createStatement();
Map parametros = new HashMap();
InputStream jasperFile = (InputStream) Thread.currentThread().getClass().getResourceAsStream("/relatorios/Geral.jasper");
jasperReport = (JasperReport) JRLoader.loadObject(jasperFile);
relatorio = JasperFillManager.fillReport(jasperReport, parametros, con);
JasperViewer viewer = new JasperViewer(relatorio, false);
viewer.setTitle("Relatório");
viewer.setVisible(true);
}[/code]
e as bibliotecas ficaram assim, conforme imagem em anexo.
