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; | } | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972201#...
