HI all,

I'm having trouble putting a GUI on an existing java server program i have. I have added a frame to the code but all it does so far is pop up, there is no interaction.. I've tried moving all of my functions accross but to no avail.. i dont know if it is an issue with inheritance or what the general code is below

  1. package rmicc;
  2.  
  3. import java.awt.Toolkit;
  4. import javax.swing.SwingUtilities;
  5. import javax.swing.UIManager;
  6. import java.awt.Dimension;
  7. import java.util.*;
  8. import java.io.*;

  137.   }
  138.  
  139.   private void jbInit() throws Exception {
  140.   }
  141. }
  142.  

I would be over the moon if some one could help, as this is really frustrating and im totally lost..

I've stripped the function code out as it would have made the code too large.

Any help appreciated

Cheers Guys

You did some modification to the code JBuilder generates for you I see

You will need to design your screen and hook up the controls to enable the interaction.
You should also go for a proper object oriented approach, which would have the RMI functionality separate from the user interface.

That way you can do something like:
  1. if (!GraphicsEnvironment.isHeadless()) {
  2. // graphical environment available, launch GUI for interactive mode
  3.  
  4. MainFrame frame = new MainFrame(serverProps);
  5. frame.validate();
  6. Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
  7. Dimension frameSize = frame.getSize();
  8. if (frameSize.height > screenSize.height) {
  9. frameSize.height = screenSize.height;
  10. }
  11. if (frameSize.width > screenSize.width) {
  12. frameSize.width = screenSize.width;
  13. }
  14. frame.setLocation((screenSize.width - frameSize.width) / 2,
  15. (screenSize.height - frameSize.height) / 2);
  16. frame.setVisible(true);
  17.  
  18. } else {
  19. // no graphical subsystem, launch server without interactive mode
  20. // using the values from the properties file
  21. Server server = new Server(
  22. Integer.parseInt(serverProps.getProperty("rmi.port")),
  23. serverProps.getProperty("server.file"),
  24. serverProps.getProperty("rmi.service"),
  25. Integer.parseInt(serverProps.getProperty("server.timeout")));
  26. try {
  27. server.startServer();
  28. } catch (RemoteException ex) {
  29. System.err.println(server.getMessages());
  30. return;
  31. } catch (IOException ex) {
  32. System.err.println(server.getMessages());
  33. return;
  34. }
  35.  
  36. }

to allow your server to also function on a machine that has no graphical shell using a configuration file to initialise it.
Mind I've not yet been able to actually test that code to see if the headless mode works, but I see no reason why it shouldn't.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

cheers for the reply,

i will have to have a look into your suggestion.. i was kind of hoping for just a quick fix to get every thing transfered over to GUI, but it is beginning to not look that easy.

Cheers

quick hacks lead to big problems later on...
