runtime.exec fails on XP

[CDJ]

Hi,
I have a problem with runtime.exec on XP. it works fine on W2K.
I get no exit value as the process does not get created.

Anyone got any ideas.I am doing this to get hold of the parameters passed from html

thanks
CDJ

public static final String Cmd = "cmd /c set";
Runtime runtime = Runtime.getRuntime();
Process pid;
try
{
pid = runtime.exec(Cmd);
}
catch (IOException e)
{
System.out.println("Content-Type: text/html");
System.out.println("Picture download failed:S");
System.out.println("<br>");
System.out.println(e.getMessage());
System.out.println("<br>");
System.out.println(e.toString());
e.printStackTrace(System.out);
System.out.flush();
throw e;
}
