Process command execution?

Question

Hi all,
i have a package(named hello) with three classes in it.
I want to call one of the classes of the package throug a process command.
i try:
String[] cmd = {"cd", "/home/test" , "java hello.run_hello"}
prcs Runtime.getRuntime().axec(cmd);
Am i doing something wrong?
Can anyone help?
Thanx!

You have to remember that what you run has to work literally.
Unless you have a program called cd, this won't work.
Perhaps you meant to call a shell like cmd to do this.
I suggest you try ProcessBuilder, this can set the working directory and run java.
Note "java hello.run_hello" won't work either as you have no program of that name.
