Running command from command prompt

Question

hai all,
iam using Javamail to send emails. for that iam using the command prompt.the code for executing the commands from the command prompt is as given below.
public static String runCommand(String s)
String result=new String();
     try
     //the command is executed and stored in 'p'
     Process p=Runtime.getRuntime().exe("cmd /c "+s);
     result=(loadStream(p.getInputStream()));
     if(p.waitFor()!=0)
     System.out.println("Exit Value = "+p.exitValue());
     System.out.println("Wait for = "+p.waitFor());
System.out.println("Result is "+result);
     catch(IOException e)
System.out.println("IO Exception");
     e.printStackTrace();
     catch(InterruptedException e)
System.err.println("Interrupted waiting for process!");
     return result;
the contents of the 'javamail' directory are
activation.jar, mail.jar, Msgmultisendsample.java and Msgmultisendsample.class
in the first call to this method i pass the string "set classpath=%classpath%;e:\javamail\mail.jar;e:\javamail\activation.jar;e:\javamail; " here i set the classpath since i will be executing the command from the command prompt.the command works fine and the exitValue() is 0.
in the second call to this method i pass the string "java Msgmultisendsample [email protected] abc 123.456.789.012 true" for running the Msgmultisendsample.class file. but i get the exitValue() as 1 and the command is not getting executed. i dont know how handle this change in the exitValue().
both the above commands works fine if i run directly from C:\ but not when called to this method.
Please help me out people, i will be glad to receieve the replies as early as possible since i have to submit this tomorrow.
Thanks in advance,
Jayanth.

well, the problem is not with the command line arguments. it doesnt matter if we get the input from the user through command prompt or GUI. The problem is only in the handling of the change in exitValue during running.
