I initially was try to get Protocol Buffers to work from Java to C++
over sockets. I am still unsure how to do this but I decided to try
and test to see if I could get a Java to Java version working over
sockets and was successful. However, I was experiencing a weirdness
which might be causing the error on the C++ side of things.
Below is my code on the server side. Basically to make a long story
short I thought that closing the stream was causing my C++ code to
fail, so I put a little sleep in there to make sure it was still
connected. Then when adding the java stuff I left the sleep in.
Basically, the code that receives the data will wait until the stream
is closed before reading the data. I thought that flushing the data
would cause the data to be sent but that apparently has no effect. Is
this my implementation or a problem with using the writeTo
function?
public class ProtoWriter {
public static void main(String[] args) {
Socket socket;
ServerSocket serverSocket;
ObjectOutputStream oos = null;
serverSocket = new ServerSocket(12345);
socket = serverSocket.accept();
oos = new ObjectOutputStream(socket.getOutputStream());
Measurement measurement = measBuilder.build();
measurement.writeTo(oos);
oos.flush();
TimeUnit.SECONDS.sleep(10);
oos.close();
