How to use wait.for() /wait() commands for MAC? Not working...

Question

I am trying to run an external application on mac using runtime.exec() and it runs fine but after it runs it suddenly terminates the program. I have a waitFor() command after the runtime.exec() waiting for that program to end. If i comment out the waitFor() then the program terminates by going through the run command. The waitFor() worked fine for PC but doesnt work for MAC... anyone know what i did wrong or alternative way of listening for it? thanks!

Answer 1

On the PC i have the following:
Process p = Runtime.getRuntime().exec("C:\\program Files\\QuickTime\\QuickTimePlayer.exe "
+file.getPath());
p.waitFor();
It basically creates a process of QuicktimePlayer and runs the file specified. I then have p.waitFor() used to wait for the user to close the application so i can do listener stuff for it- it worked for PC.
On Mac
String b= "open"+ tempFile.getPath();
Process p= Runtime.getRuntime().exec(b);
System.out.println("before wait");
p.waitFor(); .
System.out.println("app. terminated");
output:*
"before wait".
Program terminates before System.out.println("app. terminated"); but the application (quicktime) starts.
if I do this:
String b= "open"+ tempFile.getPath();
Process p= Runtime.getRuntime().exec(b);
System.out.println("before wait");
// p.waitFor(); .
System.out.println("app. terminated");
output:*
before wait
app.terminated
program terminates "normally" and I see "app.terminated".
I used Eclipse so the "red square" turns red when running it and suddenly grays out when the player appears. So to me the program terminated before the p.waitFor(); If i commented out p.waitFor() then the program goes to the System.out statement and everything goes "fine". I tried using thread.wait(), this.wait() p.wait() etc. but i get errors saying they are not owner of the thread.
hope this helps. thanks
