I'm beginner in hibernate.I'm trying a simplest example using HQL but it generates exception at line 25 ClassCastException when i try to iterate list.When i try to cast the object returned by next() methode of iterator it generates the same problem.I could not identify the problem.Kindly give me solution of the problem.

Employee.java

package one;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Employee {
@Id
private Long id;
private String name;
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public Employee(Long id, String name) {
    super();
    this.id = id;
    this.name = name;
}
public Employee()
{

}

 } 


Main2.java

package one;

import java.util.Iterator;
import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class Main2 {

public static void main(String[] args) {

    SessionFactory sf=new Configuration().configure().buildSessionFactory();
    Session s1=sf.openSession();
    Query q=s1.createQuery("from Employee ");
    Transaction tx=s1.beginTransaction();

    List l=q.list();
    Iterator itr=l.iterator();
    while(itr.hasNext())
    {
        Object obj[]=(Object[])itr.next();//Line 25 
        for(Object temp:obj)
        {
        System.out.println(temp);   
        }
    }

    tx.commit();
    s1.close();
    sf.close();

}

}
