hibernate criteria with equals for date fields

[Michael Sampson]

Maybe someone knows something about this but if not maybe just typing my question out could help resolve this either way here it goes...
So I am working with Oracle database that has a date field that will have date down to hours, minutes, seconds, not just year, month, day. Now for my domain object I have this:
class Group {

@Column(name="START_DATE")
@Temporal(TemporalType.TIMESTAMP)
private java.util.Date startDate;
}

OK .... never mind I figured it out. So the deal is even though I have it as type Date in the domain object, in the criterial statment I cannot do this:

public List<Group> findExactMatchForStartAndEndDates(String equipmentInitial,
			long equipmentNumber, Date centralTimeStartDate,
			Date centralTimeStopDate) {
return getCurrentSession().createCriteria(Group.class)
		.add(Restrictions.eq("equipmentInitial", equipmentInitial))
		.add(Restrictions.eq("equipmentNumber",new Long(equipmentNumber).intValue()))
		.add(Restrictions.eq("startDate",centralTimeStartDate)))
		.add(Restrictions.eq("endDate", centralTimeStopDate)))
		.list();}

I have to do this:

public List<Group> findExactMatchForStartAndEndDates(String equipmentInitial,
			long equipmentNumber, Date centralTimeStartDate,
			Date centralTimeStopDate) {
return getCurrentSession().createCriteria(Group.class)
		.add(Restrictions.eq("equipmentInitial", equipmentInitial))
		.add(Restrictions.eq("equipmentNumber",new Long(equipmentNumber).intValue()))
		.add(Restrictions.eq("startDate",new java.sql.Timestamp(centralTimeStartDate.getTime())))
		.add(Restrictions.eq("endDate", new java.sql.Timestamp(centralTimeStopDate.getTime())))
		.list();}  

It turns out that really a time stamp. Not a date. That was about a day's worth of work gone.
