Runtime.exec()

Process p = Runtime.getRuntime().exec("dir");

Why does the above sentence throw the following error ?

java.io.IOException: CreateProcess: dir error=2

How do we use Runtime.getRuntime().exec() to execute DOS commands ?

Please help

yeah the file is command.com .. it's somewhere in your system. THIs is an example that works on my system:

Process p = Runtime.getRuntime().exec("c:\\windows\\system32\\command.com /c dir");
p.waitFor();
System.out.println(p.exitValue());

daittCommented:
because dir is a DOS command, you need a command intepreter to run it.
Usually, you run it with "command /c dir"

daitt,

Process p = Runtime.getRuntime().exec("command /c dir");
System.out.println(p.exitValue());

Those are the lines I used. I still get the error :

java.io.IOException: CreateProcess: command /c dir error=2
