serversocket

Client program public class client implements Runnable { protected static String server_IP = "141.117.57.42"; private static final int server_Port = 5555 ; protected static String client_IP ; public static void main(String[] args) throws IOException{ final String host = "localhost"; int init = 0 ; try { InetAddress iAddress = InetAddress.getLocalHost(); client_IP = iAddress.getHostAddress(); System.out.println("Current IP address : " +client_IP); } catch (UnknownHostException e) { } try {System.out.println("hello1"); Socket socket = new Socket(server_IP,server_Port); System.out.println("hello3

i try to write simplest possible server app in Java, displaying html form with textarea input, which after submitting gives me possibility to parse xml typed in that textarea. For now i build simple serversocket based server like that: import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; public class WebServer { protected void start() { ServerSocket s; String gets = ""; System.out.println("Start on port 80"); try { // create the main server socket s = new ServerSocket(80); } catch (Exception e) {

I have two wifi modules M1 and M2 that connect to my access point. I have an android phone that connects to the same access point. I have a socket server on my android phone and the two modules join to the server as clients. Now my question is, is it possible to send a string message from my phone to module M1 without having to send anything to M2. I want to choose between clients to send the message to. Is it even possible in Java? Ok, here goes. //setting up server ServerSocket serverSocket = new ServerSocket(8000, 0, IPaddress); //creating a client socket to accept it Socket clientSocket =

I was running a few tests with sockets, and I encountered some strange behavior: A ServerSocket will refuse connections after the 50th client Socket connects to it, even if that client socket is closed before the next one is opened, and even if a delay is added between connections. The following program is my experimental code, which in its current state, throws no exceptions and terminates normally. However, if the array size of Socket[] clients is increased beyond 50, any client sockets attempting to connect after the 50th connection are refused by the server socket. Question: Why is 50 the

I'm about to program a server but am wondering if what I have in mind is possible. My program will be outputting to multiple clients on multiple ports - each port can be accessed by multiple clients. Normally I would use a threaded socket server, but in this case I need it working for multiple ports. The usage I have in mind is in a vague pseudocode below: Start server Listen for incoming connections on several ports Identify the port being connected to If port 1, start a thread listening to client and outputting message type x If port 2, start a thread listening to client and outputting

I have a problem with using a ServerSocket in my application. I'm creating the ServerSocket in the constructor of my application. The constructor of the socket calls the accept() method to wait for a client to connect. The problem is that the accept() method is freezing my whole application until a client connects. So I would like to ask if there's an alternative to creating the whole ServerSocket in a separate thread, that the constructor of the ServerSocket and its accept() method is called beside my main application? Edit: Thanks to Olivier for the advice, putting the .accept into a
