how can cmd.exe be launched from java?

Question

in .net if I wanted to open a new command line window, I could just write.

     System.Diagnostics.Process.Start("cmd.exe");

in java, however, the following code does nothing:

    new java.lang.ProcessBuilder("cmd.exe").start();
    java.lang.Runtime.getRuntime().exec("cmd.exe");

No new window is created and no Process appears in Task Manager.

Now if the application I was trying to open was "notepad.exe", then java would open it just fine.

What does this mean?
