If I understand the issue, you are trying to execute a native
application
and it is hanging. It could be process.waitfor. If I got the problem
correct
try the following code.

I have run into more problems. When I try to run osascript through
runtime.exec in a java program it appears to go into la-la land. I see
no activity, and it also appears that the interface is hung.
Use 'kill -QUIT pid' to get a thread-dump from the wedged Java app.
Not the behavior using the open command or calling the browser
directly. There I can see trace records everytime I call the plugin.
The
call statement looks OK in the trace. And I have no problem with
identical calls in the apple script editor or issuing the commands in
the terminal shell. Is there something different about the way
osascript
is executed when called from within a program?
Exactly what command and args is being exec()'ed?
Is any output produced on stdout or stderr?
Exactly what is the command and args when the exec() works?
