I've got a List of Object IDs and need to get Objects for all those Object IDs, below is what im using now, is there a way to do this using HQL?

ii = ageLimits.iterator();
while (ii.hasNext()) {
AgeLimit ageLimit = AgeLimitManager.getAgeLimit(new Long(ii.next().toString()));
productionCrew.getAgeLimits().add(ageLimit);
}

HQL will return you a list, but you can then appropriately apply the list to a set:

Code:

Query query = session.createQuery("from AgeLimit as a where a.id IN (:idList)");
query.setParameterList("idList",ageLimits);
productionCrew.getAgeLimits().addAll(query.list());
