Unable to execute a command line command using Java

Question

I am trying to run a command to add a group name. It is executed in command prompt of Windows 2003/2000
Say this is the command I want to execute:
net localgroup LordSM /add
Here LordSM is the group name.
I wrote the following code but it does not seem to work. Please suggest.
String ABC=Value1TextField.getText();
Value2Label.setText("Value is now " + ABC);
// Above is to get value from a JText Field
// Below is the code to run command for adding a group name to a System.
String ExecutedCmd = "net localgroup " + ABC + "/add";
Process p = Runtime.getRuntime().exec(ExecutedCmd);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null)
{ System.out.println(s); }
// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null)
{ System.out.println(s); }

It does not seem to work means, that no Standard Error is defined, when it executes and group name is not added as well. The following is JUnit Test Result: Hope it gives a better idea of the problem I am facing:
compile:
run:
Here is the standard output of the command:
Here is the standard error of the command (if any):
The syntax of this command is:
NET LOCALGROUP [groupname [/COMMENT:"text"]] [DOMAIN]
groupname {ADD [/COMMENT:"text"] | /DELETE} [DOMAIN]
groupname name [...] {ADD | /DELETE} [DOMAIN]
Got it
BUILD SUCCESSFUL (total time: 10 minutes 49 seconds)
I had even tried this:
Runtime rt =Runtime.getRuntime();
String[] cmd = new String[3];
cmd[0] = "cmd.exe";
cmd[1]="net localgroup";
cmd[2] =ABC + "/add";
rt.exec(cmd);
but again, it does not give any error as such, but it does not create the group name either. Please suggest. We can see the group names that are added on right clicking My Computer Icon and click Manage and then go to User & Group section. On executing either of the code nothing happens.
Thanks
