have following error log in mysql workbench:

2015-05-31t15:04:36, 27, note, aborted connection 27 db: 'planner' user: 'sudipto' host: 'localhost' (got error reading communication packets)

can please suggest how , need fix?

use rsmoviedetails.next() retrive details. rs.next() used in https://docs.oracle.com/javase/tutorial/jdbc/basics/retrieving.html.
rs.next() shifts cursor next row of result set database , returns true if there row, otherwise returns false. if row present u should retrieve data
