Hola gente!! me encuentro con el siguiente inconveniente y queria saber si la solucion que me han dado es la correcta. tengo una clase que me levanta un .jasper y me lo muestra, el proble es que me tira un error, a continuacion dejo el codigo de la clase junto con el error que me tira. me han dicho que es porque no incorporte en el classpath la siguiente libreria: commons-collections-2.0.jar

 

La Clase:
package administra.usuarios;

 import administra.db.Conexion;
 import java.util.*;
 import javax.swing.*;
 import java.sql.*;
 import net.sf.jasperreports.engine.*;
 import net.sf.jasperreports.view.*;
 public class Preview{
    public Preview(String archivo, HashMap mapa){
        run(archivo, mapa);
    }
    public void run(String archivo, HashMap mapa){
        try{
            JDialog viewer = new JDialog(new JFrame(),"Vista previa del reporte", true);
            viewer.setSize(800,600);
            viewer.setLocationRelativeTo(null);
        // Cargar el archivo .jasper
            JasperReport template = JasperManager.loadReport(archivo);
        // En mapa se especifican los parametros del reporte
            Conexion con=new Conexion();
            JasperPrint report = JasperManager.fillReport(template, mapa, con.getConexion());
        // Mostrar el reporte
            JRViewer jrv = new JRViewer(report);
            viewer.getContentPane().add(jrv);
            viewer.show();
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }
    public static void main(String[] args) {
        new Preview("D:\\Proyectos\\Escritorio\\Administra\\reportes\\classic.jasper", new HashMap());
    }
 }
 
El error:

disculpa gustavo, sinceramente no fue esa mi intencion, y no esperaba que lo "prueben y me lo confirmen", solo estaba consultando en un momento en el cual me encontraba a unas cuantas horas de poder hacerlo yo mismo, y en verdad, apuntando a que me responda quien pueda hacerlo sin "probarlo y confirmarmelo".

me prejuzgaste..

si formamos parte de un foro, debemos estar mas predispuestos.

sin mayores intenciones que aclarar tus dudas, me despido atentamente.

Saludos
