In order to run Erlang samples you need to have Erlang/OTP distribution installed - epmd binary is required in your system path. See http://erlang.org for downloads. -The Tuscany SCA Erlang binding is compatible with Erlang/OTP version R12B but -doesn't work correctly with some later versions including R14B. See TUSCANY-3759 -for details.
