I am try to query from and database using eclipse link using entities. when I use normal query records are returned from current date by when I use JPA zero records are returned. Where could I be doing wrong, Or how can I use to_char function in JPA my database is postgresql. normal sql query that returns records

select * 
from mytable 
where  to_char(transaction_date, 'YYYY-MM-DD') = '2016-01-19';

MyEntity

@Temporal(javax.persistence.TemporalType.DATE)
 private Date transaction_date;
  EntityManager e = EntityMgr.MyFact().createEntityManager();
        e.getTransaction().begin();
 Query qry = e.createQuery("from MyEntity u where  u.transaction_date=?1");
  qry.setParameter(1, new Date(), TemporalType.DATE);
