Hi,
I hope u are forming the query and call executeQuery() inside findBy() method.When u get the ResultSet, call rs.next() method .If that method returns false,there is no record in database and throw ObjectNotFoundException with some message.If there is some record get it and catch SQLException.Inside catch throw EJBException.Hope this may help u.
