hello.
Iím having difficulty trying to view the contents of a text file in a JTextArea. when i run the following program, i press the View Order button. but no data from the Order.txt file is being displayed in the text area (i've attached the .txt file to this message). how can i fix this problem? i don't know what to do.

Java Code:
import java.awt.BorderLayout;
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
import java.io.*;

public class ViewOrder extends JFrame{
   JPanel pnlText, pnlBody, pnlFooter;
   JButton btnViewOrder;
   JButton btnReturnToOrderSystem;
   JLabel jl;
   JTextArea jta;
   Container contentpane;

   public ViewOrder(){
      super("View Order");
      contentpane = getContentPane();
      contentpane.setLayout(new BorderLayout());
      pnlText = new JPanel();
      pnlBody = new JPanel();
      pnlFooter = new JPanel();
      jta = new JTextArea(250, 250);
      jta.setFont(new Font("Serif", Font.PLAIN, 12));
		
      // Set lineWrap and wrapStyleWord true for the text area
      jta.setLineWrap(true);
      jta.setWrapStyleWord(true);
      jta.setEditable(false);
		
      // Create a scroll pane to hold the text area
      JScrollPane jsp = new JScrollPane(jta);
		
      // Set BorderLayout for the panel, add label and scrollpane
      pnlBody.add(jsp, BorderLayout.CENTER); 
		
      jl = new JLabel("Text retrieved from file:");
      btnViewOrder = new JButton("View Order");
      btnReturnToOrderSystem = new JButton("Return to Order System Menu");
      pnlText.add(jl);
      pnlFooter.add(btnViewOrder);
      pnlFooter.add(btnReturnToOrderSystem);
      contentpane.add(pnlText,BorderLayout.NORTH);
      contentpane.add(pnlBody,BorderLayout.CENTER);
      contentpane.add(pnlFooter,BorderLayout.SOUTH);
      setSize(500, 500);
      setVisible(true);
		
      btnViewOrder.addActionListener(new ActionListener(){
         public void actionPerformed(ActionEvent e){
            //Read from file
            try{
               FileInputStream in = new FileInputStream("Order.txt");
	  BufferedReader iS = new BufferedReader(new InputStreamReader(in)); 
               StringWriter sw = new StringWriter();  
	  PrintWriter out = new PrintWriter(sw);
	  String il;
					
	  while ((il = iS.readLine()) != null){ 
	     out.println(il); 
	  } 
					
               out.flush(); 
	  jta.setText(sw.toString()); 

               in.close();
	  iS.close();
	  sw.close();
               out.close();			
            } 
            catch(java.io.IOException ex){
               System.out.println("Cannot read from file");
            }
         }
      });
		
      btnReturnToOrderSystem.addActionListener(new ActionListener(){
         public void actionPerformed(ActionEvent e){
            setVisible(false);
            //OrderSystem os = new OrderSystem();
            //os.setVisible(true);
         }
      });
   }
	
   public static void main(String[] args){
      new ViewOrder();
   }
}
