GUI with RMI Connection.

[Irish Rayray]

Hi all,

I have written StudentImpl, StudentInterface, StudentServer, StudentClient and StudentGui Classes I have the rmiregistery working but what i need to do is get the student Information which is a name and print it onto the text fields on the GUI.

Basically what i have is these 5 class whic create 3 students
Tom Low Street Web 2
Mary High Street Game 2
John Middle Street Web 2

and this info is already defined in the StudentServer.java
and then is changed to

Tom Lower Street Web 2
Mary Higher Street Game 3
John Middle Street Web 3

in the StudentClient.java.

I also have a gui that has 9 text fields each to be populated with a Student (Name, Address, Group) and i have this GUI working i just have no idea how to populate the fields from the client.

I can post code but thier is a fair amount of it :)

This is what i have to do with the GUI.
Create a GUI based RMI client which reads and displays the data from the remote objects. The GUI should use a 4X3 Gridlayout with JTextFields.

Thanks for the assistance in advance.

Java Code:

import java.awt.event.*;
 
import javax.swing.*;
import java.awt.GridLayout;
import java.rmi.Naming;
 
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("");
     
    String url = "rmi:///";
     
    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);    
             
            try{
                StudentInterface aTom=(StudentInterface)Naming.lookup(url+"Tom");
                FirstName.setText(aTom.getName());
                FirstAddress.setText(aTom.getAddress());
                FirstGroup.setText(aTom.getGroup());
                StudentInterface aMary=(StudentInterface)Naming.lookup(url+"Mary");
                SecondName.setText(aMary.getName());
                SecondAddress.setText(aMary.getAddress());
                SecondGroup.setText(aMary.getGroup());
                StudentInterface aJohn=(StudentInterface)Naming.lookup(url+"John");
                ThirdName.setText(aJohn.getName());
                ThirdAddress.setText(aJohn.getAddress());
                ThirdGroup.setText(aJohn.getGroup());
            }catch(Exception a){
                a.printStackTrace();
            }
    }
      public static void main(String[] args){
         new StudentGui("RMI GUI Client");
      }
}
