问题 I'm writing a simple program in Java that receives connection requests from a browser (like Firefox), parses the request for statistical info, then forwards the request to the original destination. The program then reads the response from the destination, parses the response for statistical info, then forwards the response to the browser. The pseudo code of this operation is as follows: // Accept connection from browser and read request 1. Socket browserConnection = serverSocket.accept(); 2.

问题 This question already has answers here : Official reasons for “Software caused connection abort: socket write error” (14 answers) Closed 4 years ago . I'm trying to build a simple TCP multithreaded client/server application. Whenever a Client ( Socket ) connects to the ServerSocket and send an Object ( Message ) that corresponds to the simple serializable class shown below, the server crashes when his ObjectInputStream tries to read from the client Socket getting a SocketExpection . Message

问题 I am making a prototype client & server so that I can understand how to handle reconnects. The server ought to create a serversocket and listen forever. A client may connect, send its data, and close its socket but it will not send a "I'm done and closing" type message to the server. For this reason, the server gets a EOFException when it does a readByte() since the remote client has closed. In the error handler for the EOFException , it will close the socket and open a new one. Here's the

问题 I have an app that downloads a very large file (over 50MB). Unfortunately I'm getting reports that the download fails. Below is the logcat of one such failure, which ends with a java.net.SocketException: The operation timed out . In-between it has various messages from the WifiMonitor . I don't know how to interpret these messages. Is there something special that I should do to download a large file, or is this simply a connection problem? 09-02 16:41:19.925 I/ActivityManager( 646): Displayed
