Write system call results to a text box

Question

I am making a DOS system call that creates a file. Once this file is created it gives me a "packet created successfully" message that is written to the screen.
I am using Netbeans 5.5.1 and Swing. and I want this message to be output into a JtextArea. The system call works fine and the file is created, I just can't get the message to write to my text area.
Below is a sample of my code:
private void btn_importActionPerformed(java.awt.event.ActionEvent evt) {                                          
// TODO add your handling code here:
     String Rep = txt_Repname.getText();
     String Work = txt_Workdir2.getText();
     String VOB = txt_VOBtag.getText();
     String VOBstorage = txt_VOBName2.getText();
     String Replicapath = txt_Replicapath.getText();
     String command = ("cmd /c multitool mkreplica -import -npreserve -nc -vreplica " + Rep + " -work " + Work + " -tag \\" + VOB + " -vob " + VOBstorage + " " + Replicapath);
     StringBuffer sb = new StringBuffer();
     Process p = null;
     try {
            p = Runtime.getRuntime().exec(command);
        } catch (IOException ex) {
            ex.printStackTrace();
    Scanner s = new Scanner(p.getInputStream());
    while(s.hasNextLine()) {
        sb.append(s.nextLine()+"\n");
    String result = sb.toString();
    txt_Importresults.setText(result);
    }           

Answer 1

This works okay for me.
import java.io.IOException;
import java.util.Scanner;
public class Tester {
     public static void main(String[] args) throws IOException {
           StringBuffer sb = new StringBuffer();
          Process p = null;
          try {
                 p = Runtime.getRuntime().exec("HELP");
             } catch (IOException ex) {
                 ex.printStackTrace();
         Scanner s = new Scanner(p.getInputStream());
         while(s.hasNextLine()) {
             sb.append(s.nextLine());
             sb.append(System.getProperty("line.separator"));
         System.out.println(sb.toString());
