    <p>I've encountered a very strange problem (since this always worked before) when building a client-server chat program. </p> <p>The serversocket accepts without any problem the incoming connection of the client, but when I try to read from the socket's inputstream the whole method blocks and only releases when I close the client's socket.</p> <p>I've even tried it with the sample code on docs.oracle.com, but the problem remains.</p> <p>Can anybody point me out the error I'm obviously not seeing?</p> <p>Server code:</p> <pre><code>public class Server { /** * @param args the command line arguments */ public static void main(String[] args) throws IOException { System.out.println("Creating server socket"); ServerSocket internetSocket = new ServerSocket(60000); if(!internetSocket.isClosed()) { while(true) { Socket s = internetSocket.accept(); System.out.println("accepted socket!"); BufferedReader reader = new BufferedReader(new InputStreamReader(s.getInputStream())); String line = null; while((line = reader.readLine()) != null) { System.out.println(line); } } } } } </code></pre> <p>Client code:</p> <pre><code>public class Client { public static void main(String[] args) throws IOException { Socket s = null; try { s = new Socket("localhost", 60000); } catch (UnknownHostException ex) { Logger.getLogger(Start2.class.getName()).log(Level.SEVERE, null, ex); } PrintWriter outStream = new PrintWriter(s.getOutputStream()); for(int i=0; i&lt;10; i++) { outStream.println("test"); System.out.println("Sending the message \"test\""); try { Thread.sleep(5000); } catch (InterruptedException ex) { Logger.getLogger(Start2.class.getName()).log(Level.SEVERE, null, ex); } } s.close(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
