Framework for client-server Architecture in Java !!!! With swing

Question

Hi,
Considering the scenario where we are having the Client-Server application and the rich clients at the client place , based on the frames.I have though of the logic as :
Client -----------> ClientComponentframeWorkObject(Genric Objects) ---------> reading the data from the configurable files to find where to take the user action ---------> will call the Servercomponetobject(Generic objects) can be Servlet or just a object which connects to the server(DB).I have been able to find the open-source frame work at the Apache ,all covering the server-side framework so i though of doing some work with the framework covering the client(swing) -server Archetect.Even I dont know how the existing server side framework support the swing client.
I would appericiate if someone who had worked on the client server requirement with java , could share the knowledge about the framework being used in the existing work.
regards
Vicky

Hi,
GENERIC CLIENT COMPONENT:
package com.nst.clientcomp;
import javax.swing.JFrame;
import javax.swing.JPanel;
public abstract class ClientComp extends JFrame
  protected JFrame currentframe;     
  protected JPanel  panel;
  public ClientComp()
       // To decide if the ClientComp to be Frame or the Panel.
    //panel=this;     
    //currentframe=new JFrame();
    panel=new JPanel();     
    currentframe=this;
  // Just Concentrate on the GUI , look and feel here .......And the user action will generate
  // generate the event which should call the callNextView()..The component developer have to
  // concentrate on the writing the display() and the callNextView()..
  public abstract void display() ;
  // This is the Final action.Template Pattern being Called
  public String action()
       readServerObj();
       processContent();
       display();              
       return null;
   Reading of the value object which is being Passes from the Server.As per the Design it is
   called VOFS and will be read here.Here
   1) Connect to the Server
   2) Pass the VOFC through the socket connection
   3) Also obtain the VOFS(Value object from server) 
   In certain application it can be implemented here
  public Object readServerObj()
        System.out.println("Hello from ServerObj!!! Should be implemented ");
        return null;
   Processing the Sever Value Object, which is basically as VOFS.It is processed by the
   Client.And infact the Value object from Client(VOFC) should be generated here for next
   user interaction from the Client.
  public void processContent()
        System.out.println("Hello from processContent !!! Should be implemented ");
  // Clear the Frame
  private void cleanUp()
     currentframe.dispose();
     Contains the place where next view takes.Before this is invoked the cache copy of the
     StateObject should be stored in the appropriate Data Structure......      
  public void callNextView(ClientComp com)                     
        panel.removeAll();
        com.action();
        cleanUp();
}   COMONENTS AS PER THE FRAMEWORK :
package com.nst.clientcomp;
import javax.swing.*;
import java.awt.event.*;
public class Comp1 extends ClientComp implements ActionListener
  JTextField t,t1;     
//Default display , displaying the screen.This should be the abstract method
  public void display()
    JLabel l=new JLabel("UserName");
    t=new JTextField(10);
    JLabel l1=new JLabel("Password");
    t1=new JPasswordField(10);
    t.setText("admin");
    t1.setText("admin");
    JButton b=new JButton("Login");
    b.addActionListener(this);
       panel.add(l);
       panel.add(t);
       panel.add(l1);
       panel.add(t1);
       panel.add(b);
       currentframe.getContentPane().add(panel);
       currentframe.setSize(400,400);
       currentframe.setVisible(true);      
  public static void main(String ar[]) throws Exception     
       ClientComp c1 = (ClientComp)(Class.forName(ar[0])).newInstance();
       c1.action();             
       System.out.println("Hello11");
  public void actionPerformed(ActionEvent e)
       //Do someprocessing if required
       if(t.getText().equals("admin")&&t1.getText().equals("admin"))
       callNextView(new Comp2());  
       else
        System.out.println("invalid login");     
} Similarly you can develop the other components and you have to take care of the display() and the user action Event which eventually calls the callNextView.I hope there might be the cases where this has been implemented ..
