Estou gerando um erro tbm quando executo meu programa para gerar um relatório com JasperReport. Segue abaixo o código do erro:

Se, eu retirar as barras do caminho para o arquivo teste.jasper, ele gera outro erro:

gostaria que alguém me desse uma luz no que esta errado aqui... segue abaixo o meu código:

import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.view.JasperViewer;
import java.sql.*;
import java.util.*;

public class RelatorioBibliotecaPessoal{

private static Connection getConnection() throws ClassNotFoundException, SQLException {
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://localhost/test";
String user = "root";
String password = "1234";

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

public void geraRelatorio() throws JRException, Exception {
Connection con = getConnection();
Statement stm = con.createStatement();
String query = "select * from user";
ResultSet rs = stm.executeQuery(query);

JRResultSetDataSource jrRS = new JRResultSetDataSource(rs);
Map parameters = new HashMap();

JasperFillManager.fillReportToFile("teste.jasper",parameters,jrRS);
JasperExportManager.exportReportToPdfFile("teste.jrprint");
JasperViewer.viewReport("teste.pdf",false);
}

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

Estou usando:

JCreator 4.5 PRO
JasperReport 0.6.1
IReport 0.4.0
MySQL 4.1
Eclipse 3.4
Windows XP
Se alguém puder me ajudar eu agradeço a atenção dispensada a este.
