I'm trying to use xmlrpc-1.13. Samples work fine, but I cannot understood why I fail to start xml-rpc from command-line (like "erlc test && erl -noshell -s test start"). It starts but does not listen any port. It works fine when I type "test:start()." from console. Any advices, please?

I tried this sample.

-module(test).
-export([start/0, handler/2]).
start() ->
{ok, Pid} = xmlrpc:start_link({?MODULE, handler}).
handler(_State, {call, f, [N]}) when integer(N) ->
{false, {response, [f(N)]}}.
f(N) -> N + N.

The
Code:
-s Mod Func Args
directive can lead to strange behaviors as a result of processes linking to each other, trap_exit flags, and most important, the process which calls the function passed after -s terminating. (Note the xmlrpc:start_link call?). See if you can use xmlrpc:start instead, and things should work better.

Thanks a lot! There was no xmlrpc:start so I wrote it myself in ten seconds and it works! I'll continue to study Erlang then.
