Subject AMQP version: AMQP header mismatch value 0, expecting 1
Date Fri, 22 Feb 2013 08:09:33 GMT
hallo all,

I was testing the amqp ruby gem against activemq.amqp.

Local gem version:
Successfully installed amq-protocol-1.2.0
Successfully installed amq-client-0.9.12
Successfully installed amqp-0.9.9
(Debian GNU/Linux, MRI ruby 1.9.3p0)

The simple ruby halloworld script
(http://rubyamqp.info/articles/getting_started/#hello_world_example) fails
with the following activemq log:

[ActiveMQ Transport: tcp:///127.0.0.1:53292@5672] [DEBUG] [2013-02-22

Is maybe a protocol mismatch? Which version of amqp protocol does
activemq-amqp honour?

Thank you,

Francesco
