new problem trying to view the contents of a text file in JTextArea

hello.

i've sorted out that problem with the logon program.

i have done more modifications to the code, which means that i did all that hunter9000 told me to do - to the best of my ability. when i run the program this time, i press the View Order button. when i press the button, no data from the Order.txt file is being displayed in the text area. i definitely need to know where i'm going wrong this time.

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 jtaDescription = new JTextArea();

Container contentpane;

public ViewOrder(){

super("View Order");

contentpane = getContentPane();

contentpane.setLayout(new BorderLayout());

pnlText = new JPanel();

pnlBody = new JPanel();

pnlFooter = new JPanel();

jtaDescription = new JTextArea();

jtaDescription.setFont(new Font("Serif", Font.PLAIN, 14));

// Set lineWrap and wrapStyleWord true for the text area

jtaDescription.setLineWrap(true);

jtaDescription.setWrapStyleWord(true);

jtaDescription.setEditable(false);

pnlBody.add(jtaDescription);

// Create a scroll pane to hold the text area

JScrollPane scrollPane = new JScrollPane(jtaDescription);

// Set BorderLayout for the panel, add label and scrollpane

pnlBody.add(scrollPane, 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);

pack();

setVisible(true);

btnViewOrder.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e){

//Read from file

try{

String inputFileName = "Order.txt";

File inputFile = new File(inputFileName);

FileInputStream in = new FileInputStream(inputFile);

BufferedReader iS = new BufferedReader(new InputStreamReader(in));

String iL = "";

iL = iS.readLine();

setDescription(iL);

iS.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);

}

});

}

/** Set the text description */

public void setDescription(String iL) {

jtaDescription.getPreferredSize();

jtaDescription.setText(iL);

jtaDescription.append(iL);

}

public static void main(String[] args){

new ViewOrder();

}

}

I was trying to give you general pointers that would both help with this problem, and every other problem you're going to otherwise be here asking for help with, but no matter

Some people just don't want to be helped I guess......

What's wrong with this picture?

pnlBody.add(jtaDescription);

JScrollPane scrollPane = new JScrollPane(jtaDescription);

pnlBody.add(scrollPane, BorderLayout.CENTER);
