I got this error when querying for an entity that has
@Temporal(TemporalType.TIME)
*Field*
@Basic
@Temporal(TemporalType.TIME)
private Date time;
*Query *
Query q = em.createQuery("select from " + entity.class.getName() + " entity
where entity.time=?1");
q.setParameter(1, date, TemporalType.TIME);
q.getResultList();
And got error
java.lang.IllegalArgumentException: time: java.sql.Time is not a
supported property type.

Is this unsupported feature, or I am doing some thing wrong !! (With GAE, it
is difficult to figure out, weather I am wrong, or unsupported ;)
