Student GUI with RMI Server

[Irish Rayray]

Hi All,

I have a program which creates a RMI server for a student Client like so

Name Address Class Group
Tom Low Street Web 2
Mary High Street Game 2
John Midd Street Web 2

And i have a gui which use the 3 heading but i want to get the gui to be automatically updated when run not by clicking a button to show the updated information not the information above which is displayed just after this.

Like picture below.
Lab_8.1_Client.bmp

Its just the GUI bit im stuck on i can not finad out how to populate the GUI with this information.

This is the Gui code

import java.awt.event.*;

import javax.swing.*;
import java.awt.GridLayout;

public class StudentGui extends JFrame
{
	private JTextField NameLabel= new JTextField("Name");
	private JTextField AddressLabel= new JTextField("Address");
	private JTextField GroupLabel= new JTextField("Group");
	private JTextField FirstName= new JTextField(" ");
	private JTextField SecondName= new JTextField(" ");
	private JTextField ThirdName= new JTextField(" ");
	private JTextField FirstAddress= new JTextField(" ");
	private JTextField SecondAddress= new JTextField(" ");
	private JTextField ThirdAddress= new JTextField(" ");
	private JTextField FirstGroup= new JTextField(" ");
	private JTextField SecondGroup= new JTextField(" ");
	private JTextField ThirdGroup= new JTextField(" ");
	
	StudentGui(String s){
		super(s);
		
			getContentPane().setLayout(new GridLayout(4,3));
			getContentPane().add(NameLabel);
			getContentPane().add(AddressLabel);
			getContentPane().add(GroupLabel);
			getContentPane().add(FirstName);
			getContentPane().add(FirstAddress);
			getContentPane().add(FirstGroup);
			getContentPane().add(SecondName);
			getContentPane().add(SecondAddress);
			getContentPane().add(SecondGroup);
			getContentPane().add(ThirdName);
			getContentPane().add(ThirdAddress);
			getContentPane().add(ThirdGroup);
			
			setSize(350,150);
		    setVisible(true);
		    
	}
	  public static void main(String[] args){
		 new StudentGui("RMI GUI Client");
	  }
}

StudentClient Code

import java.rmi.*;

public class StudentClient
{
    public static void main(String args[]){
        String url = "rmi:///";

        try{
            StudentInterface aTom=(StudentInterface)Naming.lookup(url+"Tom");
            StudentInterface aMary=(StudentInterface)Naming.lookup(url+"Mary");
            StudentInterface aJohn=(StudentInterface)Naming.lookup(url+"John");

            System.out.println("Name	Address		Class Group");
        	System.out.println(aTom.getName()+"	"+aTom.getAddress()+"	"+aTom.getGroup());
        	System.out.println(aMary.getName()+"	"+aMary.getAddress()+"	"+aMary.getGroup());
        	System.out.println(aJohn.getName()+"	"+aJohn.getAddress()+"	"+aJohn.getGroup());
            
            System.out.println("\n" + "Changed too:" + "\n" );

            aTom.setAddress("Lower Street");
            aMary.setAddress("Higher Street");
            aMary.setGroup("Game 3");
            aJohn.setGroup("Web 3");
            
            System.out.println("Name	Address		Class Group");
        	System.out.println(aTom.getName()+"	"+aTom.getAddress()+"	"+aTom.getGroup());
        	System.out.println(aMary.getName()+"	"+aMary.getAddress()+"	"+aMary.getGroup());
        	System.out.println(aJohn.getName()+"	"+aJohn.getAddress()+"	"+aJohn.getGroup());

        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

If you need the Rest of the Code it can be provided.

Thank You in advance.
