Hi Andrea,

1. ProcessBuilder is the preferred mechanism for running an external process in Java (introduced in 1.5).
2. External process tend to fail/hang if you do not explicitly handle the standard output/error streams.

Subject: [StarCluster] EXECUTE STARCLUSTER FROM JAVA CODE

Hi All,
I'm creating a complex project, and what I want to do is to launch the command "starclster start my custer" by pressing a button in a java swing interface.
I have created a script called run with the command inside, and what I do in my java cose is:

String[] cmd = new String[2];
                         cmd[0] = "sh";
                         cmd[1] = "run";
                         // create runtime to execute external command
                         Runtime rt = Runtime.getRuntime();
                         //Process pr = rt.exec("/path/to/script/run");
                         Process pr = rt.exec(cmd);

If I run the script from shall it works, i i press the button nothing happens. Is there someone that have done something similar? Thanks.
