public List<Meeting> getRecentlyMeetingsByAudit(Long candidateId, Long ownerId) {
    List<Meeting> meetings = new ArrayList<Meeting>();
    meetings = mgr.createQuery("select new com.integral7.ejb3.investigations.Meeting(m.id, m.scheduledDate, m.type.name, m.description, " +
        " case when exists(select id from MeetingAudit ma where ma.meeting = m and ma.audit.id = ?0) then True else False end) " +

这里主要注意 True 和 False 首字母必须大写其余小写.
