Ola, quando eu chamo o relatorio n consigo salvar com extensao .pdf, apenas em rtf e htm e tambem quando eu fecho o relatorio toda a aplicacao eh fechada

[code]package relatorio.clientes;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.HashMap;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.view.JasperViewer;

public class ClientesCadastrados {

private static Connection getConnection() throws
        ClassNotFoundException, SQLException {
    String driver = "com.mysql.jdbc.Driver";
    String url = "jdbc:mysql://localhost:3306/laboratorio";
    String user = "root";
    String password = "root";

    Class.forName(driver);
    Connection con = DriverManager.getConnection(url, user, password);
    return con;
}

/* Gera Relatorio e visualiza-o */
public void geraRelatorio() throws JRException, Exception {
    Connection con = getConnection();
    Statement stm = con.createStatement();
    String query = "select * from cliente";
    ResultSet rs = stm.executeQuery(query);

    HashMap parameters = new HashMap();

    JasperPrint jp = JasperFillManager.fillReport("C:\\Documents and Settings\\Administrador\\Meus documentos\\projetos\\distribuidora\\src\\relatorio\\clientes\\ClientesCadastrados.jasper", parameters, con);
    JasperViewer jrv = new JasperViewer(jp);
    jrv.setVisible(true);

    JasperViewer.viewReport("C:\\Documents and Settings\\Administrador\\Meus documentos\\projetos\\distribuidora\\src\\relatorio\\clientes\\ClientesCadastrados.pdf", true);
}

public static void main(String[] args) throws JRException, Exception {
    new ClientesCadastrados().geraRelatorio();
}

}[/code]

e o comando que eu uso para chamar o relatorio no botao

try { new relatorio.clientes.ClientesCadastrados().geraRelatorio(); } catch (JRException ex) { Logger.getLogger(ClienteListagemForm.class.getName()).log(Level.SEVERE, null, ex); } catch (Exception ex) { Logger.getLogger(ClienteListagemForm.class.getName()).log(Level.SEVERE, null, ex); }

espero que me ajudem

obrigado
