I have an application that goes out and logs into a data base using "login" method below. While this app is logging in, i want to show a status Dialog which implements Runnable (also described below).

The problem I am having is that the Dialog is not fully drawn until after the login thread is executed. I can't figure out why so any help would be appreciated.

   
   public class Proteus extends Frame {  
.
.
.
 public void login(Login myLogin, Frame parentFrame) {
        
   



        try {

            if (myLogin.loginName == null || myLogin.password == null || myLogin.serverAddress == null) {

                //myLogin.readConfig();
                myLogin.show();
                myLogin.hide();

            }

//**************Problem is Here*********************
//When this is enclosed in a thread, it is not fully drawn. 

            try{
            Thread myThread= new Thread(new StatusBar(parentFrame, true));
            myThread.start();
            }catch(Exception e){
                System.out.println(e);

            }


//**************End of Problem*********************
            
            System.out.println("serverAddress " + myLogin.getProteusServer());

            service = ProteusAPIUtils.connect(myLogin.getProteusServer(), true, "C:\\Cert\\client.ks");// For dynamic user
           // myIndicator.updateStatus("Sending user info...");
            

           // status.show();

            try {
                
                System.out.println("myLogin " + myLogin.getLoginName());
                service.login(myLogin.getLoginName(), myLogin.getPassword());//For dynamic user



            } catch (IOException e) {
            //    myIndicator.updateStatus(e.getMessage());
            }

            // Get an existing configuration using
            // getEntityByName( long parentId, String name, String type )
           // myIndicator.updateStatus("Now Logged In.");

            //dlg.setVisible(false);

            //new JOptionPane().showMessageDialog(this, "Now Logged In");

            System.out.println("Now Logged In");
        } catch (ServiceException g) {
           // myIndicator.updateStatus(g.getMessage());
            //new JOptionPane().showMessageDialog(this, "Unable To Login");

            System.out.println("Unable To Login");
        }
        


    }

 

public class StatusBar extends JDialog implements Runnable{

    /** Creates new form StatusBar */
    public StatusBar(java.awt.Frame parent, boolean modal) {
        super(parent, modal);
        initComponents();
        this.setLocationRelativeTo(parent);
        //this.show();
    }
.
.
.
    public void run() {

           
                StatusBar dialog = new StatusBar(new java.awt.Frame(), true);
                dialog.addWindowListener(new java.awt.event.WindowAdapter() {
                    public void windowClosing(java.awt.event.WindowEvent e) {
                        System.exit(0);
                    }
                });
                dialog.setVisible(true);
            
     
    }

I think you are running into thread safety issues with swing:

Looks more like you may want to draw the stuff in StatusBar run() first and do database stuff in the thread.

That's more of a common pattern since most IO is blocking. The IO is holding up the main thread.
