You have two options.
1 - Take sql date object and construct utils date using the getTime method of sql date
or
2 - call getTimeStamp instead of getDate , It will return object of sql timeStamp class that is actually child class of java.util.Date
1 - Date d1 = new Date(rs.getDate("date_time").getTime());
2 - Date d2 = rs.getTimestamp("date_time");
