Question

I try to establish a client / server connection for a mastermind game.
I though of using enumerations to represent the different pegs and made them serializable.

Then I have to implement the connection, using serversocket and getting the socket using accept and so on.
Once the connection is established, I first have to read for client objects, and it is where I am having problems…

Here is a piece of my code, which produces EOFException before I could ever do anything!
(the client data is send on user’s interaction).

ObjectInputStream ois =
    new ObjectInputStream(socket.getInputStream());
ArrayList<Peg> combination = new ArrayList<Peg>();
do
{
    combination.clear();
    for (int i = 0; i < 4; i++)
    {
        combination.add((Peg)ois.readObject());
    }
}
while (!checkCombination(combination));
ois.close();
socket.close();

Thank’s in advance

We need more details. How are you syncing up writes from the client and the reads on the server? Can you post more details?

BTW, is using raw sockets an absolute requirement? If not, try out RMI which does what you want to do with much less hassle (i.e. sending across Java objects transparently and much more).
