If all you want to know is "Did the app exit?", then another way is to launch QT Player yourself, exec()'ing it directly, so the Java Process really does represent the app. (You actually have to exec() the executable file inside the .app bundle, at Contents/Resources/MacOS/Quicktime Player. Refer to Apple's docs on bundle internal anatomy for details.) Then you can 'open' files for it, which 'open' will happily pass to QT Player for playblack, but your Java app can still tell when QT Player exits.
What do you mean by "exec{}'ing it directly"? You mean double click on quicktime Player or you mean this:
process qt = Runtime.getRuntime.exec("/Applications/quicktime player/macos/contents/quicktime player"); ?
I tried doing that but the console complains at the spaces between quicktime and player. I tried "\*" fix from windows, "\\" for a :"spa!
ce"
character and other methods but couldnt get it working.. any fix for that?
Also, if it gets fixed and runs do I make another process - Process B= Runtime.getRuntime.exec("open " + file.getPath());? I dont see how opening quicktime first will affect the command "open"... if you can elaborate or provide example that would be greatly appreciated..
And by the way, i am trying to make a program where it receives incoming audio and plays it on quicktime then when that particular player closes it will send back to the other person another audio.
I also discovered a way to not use quicktime player but instead use movie and moviePlayer classes to display it inside a panel.. not sure if that will work with listeners or not....
thanks

Not necessarily. That's just one way, off the top of my head.

You could also write native code that waited for an arbitrary process to terminate. You'd then figure out QT Player's process ID, pass that to the native code, and voila. You
should also recognize that closing the last window in QT Player will NOT cause it to exit. That's a Windows-ism, not a Mac-ism.

I know of no way to do that on Mac OS X. Embedding applications in one another's windows is another Windows-ism. It'd be simpler to use QuickTime for Java and create a playback component. Then you don't have to exec() anything. As I recall, QTJ is also available on Windows.
It might help if you told us what you're trying to accomplish by waiting for QT Player to exit.
