Inserting Notepad.TXT document into JTextArea(Document) ???

Question

Hi.
I've a JTextArea and I would like to insert a notepad.txt document into it for display only ie. the user is not allowed to edit it. Before I hurdle down a particular path, should I be using getDocumentBase() for this purpose?
Following is the stub code where I intend to pick up the notepad.txt document (and it would be even better to have formatted text instead of plain text):
public class ExplanatoryText extends JFrame {
  Image picture;
  Document AboutCredit;
  Font txtFont = new Font("Monospaced", Font.PLAIN,11);
  public ExplanatoryText()
    JFrame f = new JFrame("Explanatory Note : About Credit");
    f.setSize(800,200);
    f.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    Container content = f.getContentPane();
    content.setBackground(Color.white);
    content.setLayout(new FlowLayout());
    // add the LoC description inside a scrollable area
    // use getDocumentBase() to retrieve a notepad.txt document (around 2-3k)
    AboutCredit = new PlainDocument();
    JTextArea explainTxt = new JTextArea(AboutCredit);
    explainTxt.setFont(txtFont);
    explainTxt.setMargin(new Insets(5,5,5,5));
    JScrollPane scrollpanel = new JScrollPane(explainTxt);
    scrollpanel.setPreferredSize(new Dimension(550,480));
    content.add(scrollpanel, BorderLayout.CENTER);
    f.setVisible(true);
  }// end of method ExplanatoryText
}// end of class ExplanatoryTextYIA :-)

Hi. Thank-you for taking time to look at my issue.
Indeed there are many ways of doing it if it weren't an applet. If it were a simple Java program, I would simply use an io-stream, like this :
public class ExplanatoryText extends JFrame {
  Font txtFont = new Font("Monospaced", Font.PLAIN,11);
  public ExplanatoryText(String fileName, String headerTxt) throws IOException
    JFrame f = new JFrame("Explanatory Note : " + headerTxt);
    f.setSize(800,200);
    f.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    Container content = f.getContentPane();
    content.setBackground(Color.white);
    content.setLayout(new FlowLayout());
    File inputFile = new File(fileName);
    Reader readTxt = new FileReader(inputFile);
    JTextArea txtArea = new JTextArea();
    txtArea.read(readTxt,null);
    txtArea.setFont(txtFont);
    txtArea.setMargin(new Insets(5,5,5,5));
    JScrollPane scrollpanel = new JScrollPane(txtArea);
    scrollpanel.setPreferredSize(new Dimension(250,380));
    content.add(scrollpanel, BorderLayout.CENTER);
    f.setVisible(true);
  }// end of method ExplanatoryText
}// end of class ExplanatoryTextBut since it is an applet, it has run into the typical "Access Denied" problem when trying to read the input file from the locally mounted volumn.
Hence my question about whether using getDocumentBase and PlainDocument would be easier.
Thanks again for your input.
