How can i make the JTextField in the following code have a scrollbar?  I've tried results.setCaretPosition(results.getText().length() - 1); after i've filled it, but that
doesnt have any effect.

public class Interface extends JPanel implements ActionListener
      {
            private JLabel component1;
            private JTextField searchString;
            private JLabel component3;
            private JTextField alphaValue;
            private JLabel component5;
            private JTextArea results;
            private JButton component7;
            
            public Interface()
            {
                  //construct components
                              
                  component1 = new JLabel ("Search Term:");
                  searchString = new JTextField (5);
                  component3 = new JLabel ("Alpha Value:");
                  alphaValue = new JTextField (5);
                  component5 = new JLabel ("Results");
                  results = new JTextArea (5, 5);
                  component7 = new JButton ("Search");
                  
                  component7.addActionListener(this);

                  //adjust size and set layout
                  setPreferredSize (new Dimension (747, 480));
                  setLayout (null);

                  //add components
                  
                  add (component1);
                  add (searchString);
                  add (component3);
                  add (alphaValue);
                  add (component5);
                  add (results);
                  add (component7);

                  //set component bounds (only needed by Absolute Positioning)
                  component1.setBounds (5, 5, 80, 25);
                  searchString.setBounds (85, 5, 500, 25);
                  component3.setBounds (611, 5, 73, 25);
                  alphaValue.setBounds (685, 5, 60, 25);
                  component5.setBounds (345, 95, 45, 25);
                  results.setBounds (50, 120, 650, 350);
                  component7.setBounds (265, 45, 100, 25);
                               }
            }

         //add components
           JScrollPane p = new JScrollPane
          (
               results,
               JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
               JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS
          );
         
          add (component1);
          add (searchString);
          add (component3);
          add (alphaValue);
          add (component5);
          add (p);
          add (component7);

          //set component bounds (only needed by Absolute Positioning)
          component1.setBounds (5, 5, 80, 25);
          searchString.setBounds (85, 5, 500, 25);
          component3.setBounds (611, 5, 73, 25);
          alphaValue.setBounds (685, 5, 60, 25);
          component5.setBounds (345, 95, 45, 25);
          p.setBounds (50, 120, 650, 350);
          component7.setBounds (265, 45, 100, 25);

That works fine on me.
