    Default JScrollPane not showing up

    I'm trying to write a GUI that has 2 JPanels, the left panel with an image and JLabel below it, and the right one with a scrollable JTextArea. For whatever reason the JTextArea isn't showing up.

     import javax.swing.*;
    import java.awt.*;
     
    public class TextAreaDemo extends JFrame 
    {
      private JPanel p1, p2;
      private ImageIcon javaIcon;
      private JLabel jlblIcon;
      private JTextArea jtxtDetails;
      private JScrollPane scrollPane;
     
      public TextAreaDemo() 
      {
        p1 = new JPanel();
    	 p1.setLayout(new GridLayout(2, 1));
    	 p1.add(new JLabel(javaIcon = new ImageIcon("image\\java.jpg")));
    	 p1.add(jlblIcon = new JLabel("An Icon"));
    	 jlblIcon.setFont(new Font("Helvetica", Font.BOLD, 20));
     
    	 add(p1, BorderLayout.WEST);
     
    	 p2 = new JPanel();
    	 p2.add(jtxtDetails = new JTextArea("Java uses the javax.swing.ImageIcon class to represent an icon. An icon is a fixed-   size picture; typically it is small and used to decorate.", 100, 100));
    	 jtxtDetails.setLineWrap(true);
    	 jtxtDetails.setWrapStyleWord(true);
    	 scrollPane = new JScrollPane(jtxtDetails);
     
    	 add(p2, BorderLayout.EAST);
      }
     
      public static void main(String[] args) 
      {
        TextAreaDemo frame = new TextAreaDemo();
        frame.setTitle("TextAreaDemo");
        frame.pack();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);	 
        frame.setVisible(true);
      }
    }

    Aha! That's it, you forgot to add the scrollPane. Do this by doing
    add(scrollPane);

    I hope I helped!
