Java的Sleep OS X

Question

Really simple little function, but does anyone know how to sleep OS X from Java?

Cheers

Answer 1

System.exec("osascript -e 'tell application \"System Events\" to sleep'");

Answer 2

See: Making Mac OS X sleep from the command line

Create a script with the following:

#!/bin/bash
osascript << EOT
tell application "System Events"
     sleep
end
EOT

And use system to exec it.

Answer 3

    
public void gotoSleep(){
    try{
        logger.finer("Zzz...");

        if (preferences.getOS().equals("OSX") == true ){
        Process p = Runtime.getRuntime().exec
            ("/bin/bash");
        String command = "osascript -e 'tell application \"System Events\"' " 
            + " -e \"sleep\" -e 'end tell'";

        OutputStream stdin = p.getOutputStream();
        stdin.write( command.getBytes() );
        stdin.flush();
        stdin.close();
        }

    }catch( Exception e ) { 
        logger.warning( e.toString() );
    }
}

For Some reason while i was doing it it did not work without executing it through bash.
