How to persist an Entity with Object attribute?

[pippar82]

I have a problem when I try to persist an Entity Bean with 1 attribute that is an Object. I search on the web but i don't find nothing. At the end i think it's not possible but I'm not sure.

@Entity
@Table(name="TEST")
public class StatisticaVoto implements Serializable
{
 private int id;
 private Object o1;
 private Object o2;

 public StatisticaVoto() {}

 public StatisticaVoto(Object o1, Object o2)
 {
 this.o1 = (Integer)o1;
 this.o2 = (Integer)o2;
 }

 @Id
 @GeneratedValue
 public int getId()
 {
 return id;
 }

 public void setId(int id)
 {
 this.id = id;
 }

 public Object getO1()
 {
 return (Integer)o1;
 }

 public void setO1(Object o1)
 {
 this.o1 = (Integer)o1;
 }

 public Object getO2()
 {
 return (Integer)o2;
 }

 public void setO2(Object o2)
 {
 this.o2 = (Integer)o2;
 }
}
