Textarea and buttons not displaying

Question

I've been playing around with the code for awhile. I feel like I'm overlooking something really simple here. But I can't get the app to display the text-box or buttons. Makes it kinda hard to do unit testing. Any advice on oppurtunites would be greatly appreciated!
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.util.List;
import javax.swing.*;
public class FirstName extends JFrame implements ActionListener {
     private String names[] =
               "Joe",
               "Mark",
               "David",
               "Bryan",
               "Amber",
               "Abigail",
               "Skyler",
               "Melanie" };
     private JButton jButton;
     private JTextArea jTextArea;
     private JPanel jPanel;
     private JTextField jTextField;
     private JLabel label;
     public FirstName() {
          initComponents();
          List link = new LinkedList(Arrays.asList(names));
          setSize(400, 200);
          show();
     private void initComponents() {
          jPanel = new JPanel();
          label = new JLabel();
          jTextField = new JTextField();
          jButton = new JButton();
          jTextArea = new JTextArea();
          label.setText("Enter a Name to Search:");
          jPanel.add(label);
          jTextField.setColumns(20);
          jPanel.add(jTextField);
          jButton = new JButton(" OK ");
          jButton.addActionListener(this);
     public void actionPerformed(ActionEvent e) {
          boolean found = true;
          String entered = jTextField.getText();
          if (found) {
               jTextArea.setText("found");
          } else {
               jTextArea.setText("not found");
          jPanel.add(jButton);
          jTextArea.setColumns(30);
          jTextArea.setRows(5);
          jPanel.add(jTextArea);
          getContentPane().add(jPanel, BorderLayout.CENTER);
public static void main(String args[]) {
          FirstName application = new FirstName();
          application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

You've forgotten to add the panel to the frame, eg, at the end of initComponents().
Have a read of the Swing section in Sun's Tutorial to see an example of the "approved" way of creating and showing the frame. A typical example using invokeLater() is here: [HelloWorldSwing.java|http://java.sun.com/docs/books/tutorial/uiswing/examples/start/HelloWorldSwingProject/src/start//HelloWorldSwing.java]. Notice, too, that it uses setVisible(true) rather than the deprecated show().
(When you post code, use the {code} tags. The idea is that you put {code} at the start of your code and the same thing again at the end. That way your code will be properly formatted and syntax coloured when it appears here.)
