Java socket/JavaFX - sending mssgs makes clients stop working

I am trying to do checkers using java sockets. However, when I run a client, it gets stuck in a loop and stops responding.
So far my app has methods to draw a board, move checkers and create connection between a server and clients.
The connection is created correctly.
The problem is with play() which is responsible for handle server messages.
Pls help me to modify play() to have it working.

Your while(true) loop just waits for a line. It blocks the ability to perform any actions on the UI.
Spawn a separate thread to handle server communications. Obviously you need to be aware of the dangers of multi-threading and multi-thread access of model and UI data.

Passing data between class and running thread

Using code examples from stockoverflow I made a class to receive data over TCP/IP.
Class code below. It is working OK and I do receive data from other PC.
recPositions Map is build correctly. After transmission is finished I can display all data I received using getRecPositions()
This thread is started in other class that build simple HMI screen.
Thread runs and display data received from other PC.
Problem is I would like to access same data in MainWindow class (HMI)
but it always show that nothing was received.
Class MainWindow below (not all of it since there is lots of useless pushbuttons and so on)
At the very bottom I have pushbutton that should display how many positions were recorded (elements in Map) but it always show 0.
Code snippet from push button update.
System.out.println(dataServer.getRecPositions().size())
So at some point I am doing something wrong.
Thread starts and runs and I can see incoming positions. At some point after I received "EOT" I display received positions stored in Map. But when I tried to display the size of Map in main window it always show 0.

I believe the issue is in your SimpleDataServer.run method. You are creating a separate instance of SimpleDataServer from WITHIN your SimpleDataServer instance. Therefore, all of the communication is taking place in an object that your MainWindow has no direct reference to. I believe your SimpleDataServer.run method should look like this:
#Override
public void run() {
this.startServer();
}

Server issues - Java

I'm trying to make a chat function with Java. The problem is that I have two classes. One for Client and one for ClientGUI. Where the Client one has the logic parts and the ClientGUI the design. The problem is getting is in row 46 where new ListenFromServer().start(); is getting a error
No enclosing instance of type Controller is accessible. Must
qualify the allocation with an enclosing instance of type
COntroller(e.g. x.new A() where x is an instance of Controller).
So what I did was that I changedpublic class ListenFromServer extends Thread to a static. Which means public static class ListenFromServer extends Thread and now the problem that I'm getting
Error connecting to the server: java.net.ConnectException: connect: Address is invalid on local machine, or port is not valid on remote machine

How can I play Adobe Flash .SWF files in a Java Desktop Application? [duplicate]

I'm having a problem in adding my swf file to my jframe. They say that i should try the JFlashplayer but it is only a trial one. Can you give me some sample code for this?

Here is my flash player adapted from the example on their website. BCFrame is essentially a JInternalFrame. You can have it extend whatever. It will need slight modification to work, but should be strait forward. You can rip out anything that doesnt exist.
Other possible solutions are:
jffmpeg - do a search for it

Embed .swf file to my Jframe

I'm having a problem in adding my swf file to my jframe. They say that i should try the JFlashplayer but it is only a trial one. Can you give me some sample code for this?

Here is my flash player adapted from the example on their website. BCFrame is essentially a JInternalFrame. You can have it extend whatever. It will need slight modification to work, but should be strait forward. You can rip out anything that doesnt exist.
Other possible solutions are:
jffmpeg - do a search for it
