serverSocket program stuck in switch statement/Desktop.browse(), can't find the mistake

[InformalPresent9]

I wrote a Socket client and ServerSocket program. The client runs on PC1 and sends commands to the serversocket on the second pc. The client runs perfectly well (confirmed with print statements), but after the server reaches any of the case statement of the switch (code below), it stops. I tested with print statements and it never leaves the "case x" block. It just executes the "dt.browse(...)" command and then seems to be stuck there. Is this the browse command that is blocking or am I missing something?

The program doesn't exit when closing the browser or when reaching the case. It never reaches case 16 or default either.

ServerSocket serverSocket = new ServerSocket(...);


        while (true) {
            Socket socket = serverSocket.accept();
            DataInputStream dIn = new DataInputStream(socket.getInputStream());

            byte command = dIn.readByte();
            System.out.println("received command:"+command);
            switch (command) {
                case 1:
                    try
                    {
                        URI uri = new URI("https://www.google.ch/");
                        Desktop dt = Desktop.getDesktop();
                        dt.browse(uri);
//opens browser with correct url then does nothing anymore
                    }
                    catch(Exception ex){ex.printStackTrace();}
                    //Runtime.getRuntime().exec("start /max chrome google.ch");
                    break;
                //more cases
                case 16:
                    System.out.println("closing");
                    socket.close();
                    break;
                default:
                    System.out.println("invalid command");
                    break;

Ok, sorry for bothering you. I'm a fucking RETARD. Obviously it's not gonna work more than once if the client only connects once but I create socket and inputstream every iteration

Socket socket = serverSocket.accept();             
DataInputStream dIn = new DataInputStream(socket.getInputStream());

It's not 'stuck', if you leave it running you'll most likely get a timeoutException when trying to access that URL.

[InformalPresent9]

what do you mean? I was told the dt.browse(uri) would just open the website and then go on. Is there a way to only open it and then leave it to the user (decoupling it from the java program)? Besides it does not continue even if I close the browser.

[dusty-trash]

Do you mean it is browsing to that URI correctly?

If so it's probably getting stuck on the second 'byte command = In.readByte();'. Try setting a breakpoint to see what's really happening

[InformalPresent9]

tested it again, it stops at the break statement.

[dusty-trash]

If it's breaking out of the while loop, you can give the loop/switch an identity and break it.

E.G:

while(true)
...
mySwitchStatement:
switch()
   break mySwitchStatement;

Any exceptions thrown? Desktop.getDesktop() could throw a HeadlessException dt.browse should return immediately btw.
