rxtx - Java application won't exit if serial port is left open -


i'm using netbeans make jfx app talks arduino uno. have installed rxtx on 64 bit os x box , seems working.

in main controller of application in initialize() method this:

 commportidentifier  portid = commportidentifier.getportidentifier("/dev/tty.usbmodem1d1111");  this.serialport = (serialport) portid.open("box app", 1000);  // this.serialport.close();

this great except when close application's window without calling serialport.close() function, app/jvm stays running in background. i've tried overriding dispose() method of controller , adding platform.exit(). platform.setimplicitexit(true); set true, explicitly.

not sure else can do. if user closes app before serial i/o done, apparently hang. how can force port closed when application window closed?

this code:

   topframe.addwindowlistener(new windowlistener()         {             public void windowclosing(windowevent e)             {                 emsclient.close();             }             public void windowopened(windowevent e) {             }             public void windowclosed(windowevent e) {             }             public void windowiconified(windowevent e) {             }             public void windowdeiconified(windowevent e) {             }             public void windowactivated(windowevent e) {             }             public void windowdeactivated(windowevent e) {             }         });`

will attach event close window

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
