[rabbitmq-discuss] rabbitmq erlang client

[Orion Henry]

Hello,

I'm trying to get the rabbitmq-erlang-client to work and I've not been
able.  My ruby client has been working great and is already in
production but currently my erlang app needs to os:cmd("publish.rb")
and I'd like to keep that in the erlang vm for obvious reasons.

My test code looks like this:

test_client() ->
    io:format("--- begin~n"),
    Connection =
amqp_connection:start_link("mylogin","mypass","127.0.0.1",<<"/myvhost">>),
    io:format("--- got Connection = ~p.~n",[Connection]),
    Channel = amqp_connection:open_channel(Connection),
    io:format("--- got Channel = ~p.~n",[Channel]).

this seems to work ok but I get a "Have a look into this one: closed"
message a split second later.   If I add anymore code, such as a

    X2 = lib_amqp:declare_exchange(Channel, <<"abc">>),

I get this error.  (I'm not very good yet at understanding erlang
error message so please forgive me if this is obvious).

I'm currently using erlang client 3a9ce636e283 and rabbitmq_server
200803291005.  That said I have not been able to get the erlang make
all_tests work against the rabbitmq server.
