serversocket

问题 When creating a client server application (serversocket), would I create 2 seperate projects or can I do this in a single project? I'm a little confused as to what type of project this will be, and more confused as to how I can launch both the client and server. Or would I have to manually fire up terminal and execute the jars? This will be a serversock and a client that connects to it and sends simple messages. 回答1: Assuming that your client and server are started by invoking a Java main()

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I have yet another question about my push server. For some reason the server will only accept one connection during it's lifetime. Even after the first connection has been closed, the server won't do anything. I

问题 So I have created a Java code to handle clients when triggered by my TP-Link WR841N. The problem is that I am getting no response at all, I have already configured my router for Port Forwarding and Port Triggering but it is not working. I am not getting any output on console. Please help me out... Main.java package com.geek; public class Main { public static void main(String[] args) { DHCP_CustomServer server = new DHCP_CustomServer(2222); server.run(); } } DHCP_CustomServer.java package com

问题 I'm trying to connect 2 Android devices through sockets, but why isn't it working? I've tried replacing the Host Address with IP Address but it didn't work out. Server Side (extends AsyncTask): ServerSocket server; int port; String hostName server = new ServerSocket(0); port = server.getLocalPort(); //is sent to client via OR code for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = en.nextElement(); for (Enumeration

问题 I am using a server socket in linux and I need to close it and reopen before the time_wait TCP status expires. I set the reuse address option of the server socket before the binding but it still throws a BindException. I also tried this http://meteatamel.wordpress.com/2010/12/01/socket-reuseaddress-property-and-linux/ but it still doesn't work. To open a server socket i use: ServerSocket ss = new ServerSocket(); ss.setReuseAddress(true); ss.bind(new InetSocketAddress(12345)); and to close: ss

问题 I'm currently involved in a project at school in which we are building a communication system to be used on Android phones. For this, we will be using a server which opens sockets towards all clients, making them communicate. I've done several chat applications before without any problems with sockets or thread handling but this time, for some reason, it boogles my mind. The problem is that the application starts to listen as soon as I initiate the ServerSocket object, serverSocket = new

问题 I am getting data from avl system as you can see with this format : *HQ,4106016320,V1,090458,A,5257.4318,N,15840.4221,E,000.00,000,101115,FFFFFBFF,250,01,0,0,5# As you can see the data that i get from the gps is : As you can see in some lines the data is unreadable .why this problem happened?

问题 I've just posted a part of my program. The first time I run the program I could give the input from a client and the server crosses the accept, but when the program runs for second loop it gets stuck in the mysocket.accept . Making the socket non-blocking doesn't solve this.Does anyone know how to clear this error? class Memory(threading.Thread): def __init__ (self): threading.Thread.__init__ (self) def run(self): global data_queue while True: sleep(0.1) mysock.listen(5) print "waiting for

问题 I'm writing a networking program in Java. I use ServerSocket and Socket objects to send and receive messages using TCP. My program runs fine if run for a short time however if I run it for a longer time, I get the following error: java.net.SocketException: No buffer space available (maximum connections reached?): connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at
