Starting an mac application

[Christian]

Hello


I have got some Mac Application that I want to start with some parameters

....
ProcessBuilder pb = new
ProcessBuilder(tooFreeApp.getPath(),"-data",myRootPath.getPath(),apparguments);
pb.redirectErrorStream(true);
process = pb.start();
BufferedReader i = new BufferedReader(new InputStreamReader(
process.getInputStream() ) );
String read;
while (null != (read =i.readLine())) {System.out.println(read);}

....


the code above seems to work on windows with some .exe file but not on
mac with the corresponding .app file.

Someone got an idea what I could do?

Well, .exe is an entirely different concept than .app. .app is nothing
but a package, a directory if you will, so passing parameters to it
isn't actually passing it to the executable but to the whole package.
So the actual UNIX executable is really located inside that package.
Let's say you have an app called Foo.app, then your executable would
be in Foo.app/Contents/MacOS/Foo. So you may wanna try to pass your
parameters directly to that and see if that works.

Hope this helps.

this doesn't work ...
if I start Foo.app/Contents/MacOS/Foo directly the program will just crash.

may be I can use
open -a Foo.app parms somehow ?

open Foo.app

does not work with process builder, but with Runtime.getRuntime().exec()

though I seem to be unable to pass arguments to the program that way
which is crucial.

someone a hint?

I just need to start that application with some arguments in a
subprocess... so I know when the app terminates.

thats something that simply must be easy ... shame on me I havend
figured it out by now ...
but I am simply clueless..

please help.
