Pessoal

public class Relatorios {

     private static Connection getConnection() throws
        ClassNotFoundException, SQLException {
        String driver = "com.mysql.jdbc.Driver";
        String url = "jdbc:mysql://suporte02/sasi";
        String user = "root";
        String password = "xxxxxx";

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

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

    private void geraRelatorio() throws JRException {
        //supondo que o teu ficheiro teste.jasper esteja dentro da tiua aplicação
        URL arquivo = getClass().getResource("D:/Programas java/sasi/relMovimentacao/relMovimentacoes.jasper");
        JasperReport jasperReport = (JasperReport) JRLoader.loadObject(arquivo);
        //aqui, como não vais passar parâmetros para dentro do relatório, e porque estou a assumir que não tenhas ligação com base de dados, os dois ultimos parametros são nulos
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null);
        //isto mostra.te o viewer, penso que é a melhor maneira, pois assim a pessoa escolhe o formato em que quer gravar, e o sitio onde gravar
        JasperViewer jrviewer = new JasperViewer(jasperPrint, false);
        jrviewer.setVisible(true);
    }
}

E o erro é esse:

Exception in thread “main” java.lang.NullPointerException

N sei pq esta com esse erro !

Usa o debug e vê onde tá dando null

#3

Fiz de outro jeito (q eu acho ate melhor) e esta dando outro erro:

Classe p fazer a conexao:


package classes;

import java.sql.*;

/**
 *
 * @author Administrador
 */
import java.sql.Connection;
import java.sql.DriverManager;

public class Conexao {

    public Connection getConnection(){

  try{
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    String driver = "jdbc:mysql://suporte02/sasi";
    Connection con = DriverManager.getConnection(driver,"root","root");
    return con;
  }
    catch(Exception e){
    e.printStackTrace();
     }  
   return null;
  }
}

Acao do botao imprimir p chamar o jviewer:


 private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {                                         

        Conexao ac = new Conexao();
        JasperPrint rel = null;

        try {
            Connection con = (Connection) ac.getConnection();
            HashMap map = new HashMap();
            String arquivo = "D:/Programas java/sasi/src/relMovimentacao/relMovimentacoes.jasper";
            JasperReport jasperReport = (JasperReport) JRLoader.loadObject(arquivo);

            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, map,con);

            JasperViewer jrviewer = new JasperViewer(jasperPrint, false);
            jrviewer.setVisible(true);
        } catch (JRException ex) {
            Logger.getLogger(Principal.class.getName()).log(Level.SEVERE, null, ex);
        }


    }

E o erro é esse:

Resolvido

Peguei todos os .jar q estavam na LIB do ireport e coloqueis todos na app ! Deu certo !

Valeu pessoal !

Estou com um pequeno problema de novo : /

Estou usando o ireport 3.0 !
Na minha máquina ta rodando tudo 100%.
Qnd eu coloco a aplicacao em outra maquina, e vou abrir o relatorio ele nao abre !

O caminho ta correto.
Qnd o relatorio nao tem paginas, ele mostra a msg: …" ñ contem paginas. " (ate ai tudo bem).

Mas qnd tento abrir um relatorio q contem paginas ele nao abre !

Sera q eh a versao do java q ta instalada na tal maquina ?

O pior eh q nao eh problema de biblioteca… Ja importei todas do ireport 3.0 e mesmo assim esta dando o mesmo erro !

#10

Não abre o que? O PDF?
