Thread: EOFException

Could that be right?

What does the trace/debug output show? What order do the events occur in?

Why does the AllInOne program work?

2012-07-27 21:13:12.376 - DEBUG: Written: 68

2012-07-27 21:13:12.377 - DEBUG: Written: 72

2012-07-27 21:05:00.739 - DEBUG: Can read: 0

The 140 = 68+72.

Is the available=0 from the same object as the 140?

I honestly have no clue why the AllInOne works and why this one doesnt. I posted the output in the posts above your post. Or is that not what you mean?

Edit, wait a sec, the only thing that changed is my logger. could that be it?

edit2, Nope

I editted my last post.


What does the trace/debug output look like for AllInOne?

Also yes that is from the same object.

What is that about?

Is the trace is for AllInOne when there is no problem? It looks like there is a wait between the call to nextInt() and when the data is written, since there is no EOF problem.

AllInOne worked differently for me from one execution to the next. Sometimes there was an EOF exception and sometimes not.

Try changing the code so it reads from the same class object. The posted code gets a new class objects every time it does a read.

What is this? is this real life? now it works. But why?

I changed my FileSendRecieve to the following:

public class FileSendRecieve {
	Socket socket;
	OutputStream socketOut;
	InputStream socketIn;
	DataInputStream dataIn;
	DataOutputStream dataOut;
	FileInfo fileinf = new FileInfo();
 
	public FileSendRecieve(Socket socket) {
		try {
			socketOut = socket.getOutputStream();
			socketIn = socket.getInputStream();
			dataOut = SocketUtil.wrapOutputStream(socket);
			dataIn = SocketUtil.wrapInputStream(socket);
		} catch (IOException e) {
			e.printStackTrace();
		}
		this.socket = socket;
	}
 
	public void sendFile(String name, String directory) throws IOException {
		File file = new File(name);
		fileinf.setFile(file);
		fileinf.write(dataOut);
	}
 
	public void recieveFile() throws IOException {
		fileinf.read(dataIn);
		fileinf.print();
	}
 
	public void stop() {
		SocketUtil.close(socketIn);
		SocketUtil.close(socketOut);
		SocketUtil.close(socket);
	}
}

So im not making new objects anymore. Maybe better for performance as well.

Also something TOTALLY different, what is the difference between the code=java tags and the highlight=java?

I think having two BufferedInputStreams in parallel was confusing the system. Which one would be keeping track of what bytes had been read? Having only one removes the confusion.

[code = java]

Maybe the spaces around the = confuses the forum's code.
