copied!<p>Hi I have a GUI application that is working fine. I created a socket server. When I create a new object of the Server class in program the GUI application stops responding.</p> <p>This is my server class. If I do</p> <pre><code>Server s = new Server(); </code></pre> <p>in my main application it stops working. How should I add it? Making a new thread? I tried</p> <pre><code>Thread t = new Thread(new Server()); t.start(); </code></pre> <p>but the problem persisted. Please, I'll appreciate your help.</p> <pre><code>package proj4; import java.net.*; import java.io.*; public class Server implements Runnable { ServerSocket serverSocket = null; Socket clientSocket = null; ObjectOutputStream out = null; ObjectInputStream in = null; int port; static int defaultPort = 30000; boolean isConnected = false; Thread thread; DataPacket packet = null; public Server(int _port) { try { serverSocket = new ServerSocket(_port); serverSocket.setSoTimeout(1000*120); //2 minutes time out isConnected = true; System.out.println("server started successfully"); thread = new Thread(this); thread.setDaemon(true); //thread.run(); } catch (IOException e) { System.err.print("Could not listen on port: " + port); System.exit(1); } try { System.out.println("Waiting for Client"); clientSocket = serverSocket.accept(); System.out.println("Client Connected"); thread.run(); } catch (IOException e) { System.err.println("Accept failed."); System.exit(1); } try { out = new ObjectOutputStream(clientSocket.getOutputStream()); System.out.println("output stream created successfully"); } catch (IOException e) { e.printStackTrace(); } try { in = new ObjectInputStream(clientSocket.getInputStream()); System.out.println("input stream created successfully"); } catch (IOException e) { e.printStackTrace(); } } public Server() { this(defaultPort); //server listens to port 30000 as default } public void run() { System.out.println("Thread running, listening for clients");//debugging purposes while (isConnected) { try { packet = this.getData(); Thread.sleep(0); } catch(InterruptedException e) { e.printStackTrace(); } } } public DataPacket getData() { try { packet = (DataPacket)in.readObject(); } catch (Exception ex) { System.out.println(ex.getMessage()); } return packet; } public void sendData(DataPacket dp) { try { out.writeObject(dp); } catch (IOException e) { e.printStackTrace(); } try { out.flush(); } catch (IOException e) { e.printStackTrace(); } } public void closeConnection() throws IOException { out.close(); in.close(); clientSocket.close(); serverSocket.close(); } } </code></pre>
