Re: [Rcrss] Re: [robocup-rescue-s] yab api for 0.49.x

Dear Hossein,

I've tried with Saboorian's release with no luck (same errors).
I also tried yours and I'm still having some troubles communicating with the
kernel. This time a negative array is created because the receive method
fails:
                       int length = in.read();
                        length = length<<8 | in.read();
                        length = length<<8 | in.read();
                        length = length<<8 | in.read();
                        byte[] buffer = new byte[length];
since DatainputStream.read returns -1 when it couldn't read from the socket,
then there must be a communication problem.
This could be easy to fix if I just check for negative values on every
in.read(), but I'm just wondering... am I the only one experiencing these
problems? Does this version works out-of-the-box for you?

thanks,
David

ps: I'm using rescue-0.49.8
