eofexception

I want to read multiple objects (my own class Term) that I have output to a .dat file, but I always get a nullPointException or EOFException. ObjectInputStream inputStream = new ObjectInputStream(new FileInputStream(masterFile)); Object o = null; while(( o = inputStream.readObject()) != null){ Term t = (Term)o; System.out.println("I found a term"); } See the Javadoc. readObject() doesn't return null at EOF. It throws EOFException. The only way it can return a null is if you wrote a null at the other end, and that's not necessarily a good reason for terminating the read loop. In short your code

My client/server application currently keeps opening and closing new connections every time it wants to send/receive data. I'm trying to change it so it will have one persistent connection. The problem I'm having is the socket's DataInputStream on the server keeps throwing EOFException's when I just want it to block until it receives the next batch of data. I thought about just simply writing the server like this... while socket is open { while at socket's DataInputStream's EOF { wait a second } //If we're here, then we have some data do stuff } ... but this is extremely ugly and not the

i don't know why java.io.EOFException appear. i want to write a file after i get binary stream from server. Here's my code inputStream = new DataInputStream(new BufferedInputStream(connection.getInputStream())); FileOutputStream fos = new FileOutputStream("D:/Apendo API resumable download.txt"); byte b = inputStream.readByte(); while(b != -1){ fos.write(b); b = inputStream.readByte(); } fos.close(); Stack trace java.io.EOFException at java.io.DataInputStream.readByte(DataInputStream.java:267) at HttpRequestJSON.JSONRequest.sendRequest(JSONRequest.java:64) at HttpRequestJSON.Main.main(Main.java

I have created small CLI client-server application. Once the server is loaded the client can connect to it and send commands to the server. The first command is to get list of files that server is loaded with. Once the socket connection is established. I request user to enter a command. ClientApp.java Socket client = new Socket(serverName, serverPort); Console c = System.console(); if (c == null) { System.err.println("No console!"); System.exit(1); } String command = c.readLine("Enter a command: "); OutputStream outToServer = client.getOutputStream(); DataOutputStream out = new

I've hosted a MySQL DB in a webserver . I've granted all privledges and allowed my IP to connect to this database remotely from my local computer. It gets connected and I'm able to retrieve data from the database to my Java Swing application. But, sometimes I get this error message and my connection with the hosted DB fails. Error is shows below: Apr 7, 2012 12:49:20 AM scm.new_fas txtSearchKeyReleased SEVERE: null com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.io.EOFException MESSAGE: Can not read response

Here's the question in simplest way. I create a HTTPS connection to my server through proxy using HttpUrlConnection Object. My proxy closes the connection but my code still tries to reuse the same connection. And so I get EOFException. How do I handle such cases? kturney I'd recommend disabling the http.keepalive system property. The performance section of the documentation indicates that socket connections will be reused when possible. It sounds like it is trying to reuse the connection, but the proxy has already closed it. On this post , Darrell also indicates that changing the system

I have a problem using an ObjectInputStream and I have been struggling with it for 2 days now. I tried to search for a solution but unfortunately found no fitting answer. I am trying to write a client/server application in which the client sends objects (in this case a configuration class) to the server. The idea is that connection keeps alive after sending the object so it is possible to send a new object if necessary. Here are the important parts of my client code: mSocket = new Socket("192.168.43.56", 1234); mObjectIn = new ObjectInputStream(mSocket.getInputStream()); mObjectOut = new
