Thread: Program is working when using "Step into" in debugging mode, but not when running. (Sockets)

Hello!

I have three classes: Server, Client and Cap. I'm trying to send Cap from Server to Client and back through sockets. Server implements runnable and in the run-method there is a infinite while-loop that look like this:

try {
out.writeObject(new Cap());
out.flush();
 
Cap cap = (Cap) in.readObject();
 
boolean bol = false;
 
if(cap.getValue()==2) {
 
 bol = true;
 }
 
out.writeBoolean(bol);
out.flush();
} catch (IOException ex) {
                JOptionPane.showMessageDialog(null, "Something is wrong");
                break;
} catch (ClassNotFoundException ex) {JOptionPane.showMessageDialog(null, "Something is wrong");}
 
}

In the run-method but before the while-loop I did this:

out = new ObjectOutputStream(socket.getOutputStream());
in = new ObjectInputStream(socket.getInputStream());

In the Client-class I also have a while loop like this:

try {
 
     Cap cap = (Cap) in.readObject();
 
     textBox.setText(cap.toString());
 
     while(!JButtonHasBeendPressed) {
 
      }
 
      out.writeObject(cap);
      out.flush();
      bol = in.readBoolean();
 
      if(bol) {
 
       //Do something
      }
      else {
       //Do something else
       }
       JButtonHasBeendPressed = false;
 
   } catch (IOException ex) {
       //Do something
   } catch (ClassNotFoundException ex) {
      //Do something
   }
 }

Before the while-loop I did this:

out = new ObjectOutputStream(socket.getOutputStream());
in = new ObjectInputStream(socket.getInputStream());

When I'm debugging the Client-program it works just exactly as I want - the program gets inside "if(bol)". When I run the program, Server can send the object to Client, but after that something goes wrong. As you can see in the code I have a JButton in the Client-class, that is setting JButtonHasBeendPressed = true, but nothing happens when I'm pressing it. I get no error messages, literally nothing happens.

When I'm debugging both the server and the client, a IOException occurs at out.writeBoolean(bol); in the Server-class

Please don't post multiple threads on the same topic. This illustrates how confusing it is, because in the other thread, this problem has been solved. Return to the other thread, remove [SOLVED] if appropriate, and keep working it there with any new info.

This thread is closed.

Reopened in response to OP request.

Yes, soon. The problem seems to be with the while-loop that is waiting for the JButton to be pressed.

Well, I have a listener for the JButton. In the actionPerformed-method I have a boolean that becomes true when I'm pressing the button. That will break the below loop.

 while(!JButtonHasBeendPressed) {
 
      }

I managed to get it work. Thanks!
