Hibernate version: 3.1.1, Hibernate Annotations:3.1beta8

I am switching from mapping files to annotations.

While mapping a Calendar field as follows I get a ClassCastException.

@Temporal(TemporalType.TIMESTAMP)
@Column(name="startDate", nullable = false)
public Calendar getStartDate() {
return startDate;
}

what is the correct annotation to be used?

thanks,

and the stacktrace is.

obj.setCalendarProperty(new GregorianCalendar());

//create the object
Transaction tx = super.session.beginTransaction();
super.session.saveOrUpdate(ato);
Integer atoId = ato.getId();
super.assertNotNull(atoId);
tx.commit();

I've tried it by explicitly specifiying the 3 possible TemporalType's to no avail. I'm generating the ddl, and that is occuring correctly (TemporalType.DATE to MySql date, TemporalType.TIME to MySql time, TemporalType.TIMESTAMP to MySql datetime).

Here is the ddl:

create table hibfun_all_types (
id integer not null auto_increment,
calendar_property datetime,
primary key (id)
);

protected Calendar calendarProperty;
@Column(name="calendar_property")
@Temporal(TemporalType.TIMESTAMP)
@org.hibernate.annotations.Type(type="calendar")
public Calendar getCalendarProperty() {
return calendarProperty;
}

Thanks, that's fixed
