> I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code:
> {code}
> public boolean login(final String username, final String password) {
>     // block inbound messages
>     session.getConfig().setUseReadOperation(true);
>     // send the login request
>     final LoginRequest loginRequest = new LoginRequest(username, password);
>     final WriteFuture writeFuture = session.write(loginRequest);
>     writeFuture.awaitUninterruptibly();
>     if (writeFuture.getException() != null) {
>         session.getConfig().setUseReadOperation(false);
>         return false;
>     }
>     // retrieve the login response
>     final ReadFuture readFuture = session.read();
>     readFuture.awaitUninterruptibly();
>     if (readFuture.getException() != null) {
>         session.getConfig().setUseReadOperation(false);
>         return false;
>     }
>     // stop blocking inbound messages
>     session.getConfig().setUseReadOperation(false);
>     // determine if the login info provided was valid
>     final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage();
>     return loginResponse.getSuccess();
> }
> {code}
> I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to `readFuture.awaitUninterruptibly() `.
> I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously.
