JFrame size is not correct althrough specified in code

Question

Hi all,
I've made a GUI, which is being run as a thread since I have incoming/outgoing socket threads also running for an application. It seems that none of the fields are being populated into my JFrame. What is wrong?
import java.net.*;
import java.io.*;
import java.util.*;
import javax.swing.*;
import java.awt.event.*;
public class Server extends JFrame implements ActionListener, ItemListener
     JCheckBox jcbServer=new JCheckBox("Run as Server",false);
     JTextField jtfChat=new JTextField("Chat");
     JTextField jtfUsername=new JTextField("Username");
     JTextArea jtaMessageBox=new JTextArea();
     boolean isServer=false;
     String message,text,content,sendMessage,user;
     int pos;
    public Server()
         run();
    public void run()
         int frameWidth=400,frameHeight=150;
         Vector<Connection> connections= new Vector<Connection>();
         JFrame frame = new JFrame("Chatterbox");
         frame.setSize(frameWidth,frameHeight);
         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         frame.add(jtfUsername);
         frame.add(jcbServer);
         frame.add(jtfChat);
         frame.add(jtaMessageBox);
         jtaMessageBox.setEditable(false);
         frame.pack();
         frame.setVisible(true);
        ServerSocket serverSocket=null;
            Connection conn;
        boolean listening = true; 
          if (isServer==true)
               try
                 serverSocket = new ServerSocket(4444);
             catch (IOException e)
                 System.err.println("Could not listen on port: 4444.");
                 System.exit(-1);
               try
                  while (listening)
                       Socket socket=serverSocket.accept();
                       conn=new Connection(socket);
                        connections.add(conn);
                        conn.start();
                        message=conn.getMessage();
                        if (message.startsWith("/gameMessage"))
                             content=message.substring(13);
                             pos=content.indexOf("/");
                             user=content.substring(pos-1);
                             text=message.substring(pos+1);

                        else if (message.startsWith("/Leaving"))
                             content=message.substring(9);
                             pos=content.indexOf("/");
                              user=content.substring(pos-1);
                             jtaMessageBox.append(user +" has left");
                  serverSocket.close();
               catch (IOException ex)
    public void actionPerformed(ActionEvent ae)
         if (ae.getSource()==jcbServer)
              if (jcbServer.isSelected()==true)
                   isServer=false;
              else if(jcbServer.isSelected()==false)
                   isServer=true;
         else if (ae.getSource()==jtfChat)
              message="/gameMessage"+user+"/"+jtfChat.getText();
         else if (ae.getSource()==jtfUsername)
              user=jtfUsername.getText();
     public void keyReleased(java.awt.event.KeyEvent ke){}

Well, to start off with:
Your title on your post has nothing to do with what you are asking in your question,
2nd-your question does not reflect what you ask in your title
Try printing the results out to your console: System.out.println(), I believe you'll find your calls do not return anything to show.
Use your debugger to trace through your project to visually see and find what is happening.
BTW: if you want to fix the displayed size problem with your JFrame: make a JPanel and setPerferredSize to what you want add it to your JFrame and then add all of your other GUI components to your JPanel. When you pack your JFrame, it will take the size of your JPanel.
