When I start program without tcp server, my program work correctly but when tcp server gets involved my second gui screen is not working. I am asking why do I have such a problem.How to make server ready.
This my ServerClass;

this.serverSocket = serverSocket;
}
public void startServer() {
try {
while (!serverSocket.isClosed()) {
Socket socket = serverSocket.accept();
System.out.println("Bağlandı");
ClientHandler clientHandler = new ClientHandler(socket);
}
} catch (IOException e) {
}
}
public static void main(String[] args) {
Svg svg = new Svg();
svg.getjBaslat().addActionListener(new ActionListener() {
int rectNo;
@Override
public void actionPerformed(ActionEvent e) {
if (svg.getRectNo().getText().equals("")) {
rectNo = 0;
} else {
rectNo = Integer.parseInt(svg.getRectNo().getText());
}
svg.setVis();
DrawShapes dShapes = new DrawShapes(rectNo);
try {
ServerSocket serverSocket = new ServerSocket(9090);
Server server = new Server(serverSocket);
server.startServer();
} catch (IOException e1) {
e1.printStackTrace();
}
}
});
}

I tried so many different ways to solve this problem but I can't see my fault. Maybe I made mistake thread section or made server connection false. I don't find any solution.
Thanks to all concerned.
