Rserver 0.5-3 won't work with GUESS ver. 1.0.4 beta

[Katz Kawai]

Hi,

I've been trying to use Rserve 0.5-3 with GUESS ver. 1.0.4 beta on
Ubuntu 9.10 beta, but I ended up getting the following result:

java.lang.Error: java.lang.Error: Handshake failed: The server uses more recent
protocol than this client. [request status: no error]

Is there any plan for GUESS to support the "recent protocol" above?
If not, which version of Rserve should I use, instead?

Any advice would be very much appreciated. Thank you very much for your help
in advance.
