Exe running from java fails to get user input .Help me...

Question

I have an DOS based exe.It just asks for input for a number from the user and prints the number it gtes.
When I try to execute this program from Java with the following code
import java.lang.Runtime;
import java.lang.Process;
import java.io.*;
public class runtimetest     {
     public static void main(String[] args)     throws Exception {
          Runtime rt = Runtime.getRuntime();
          Process p = rt.exec("myExe");
nothing happens.Thatis It doesnot ask for the input .and I am just unable to know whether its running or not.
What could be wrong?
What is the other means to tun the DOS based exe that accepts user inputs , from Java.
Plz help me as I am in urgent need.

try this
Runtime r = Runtime.getRuntime();
          Process p = null;
          try
               System.out.println("Exe will be called");
               p = r.exec("cmd.exe /c start c:/ur exe path ");
               p.waitFor();
          catch (Exception e)
               e.printStackTrace();
          }
