[rabbitmq-discuss] Connection problems with Rabbitmq 1.4.0

Wed Nov 26 10:49:47 GMT 2008

Hi,

At the moment I have a problem connecting to the RabbitMQ broker. I'm
running version 1.4.0 on Erlang R12B4. The OS is OS X 10.5.5. Before
running any examples I did a reset of the rabbitmq broker.

I tried connecting with a ruby client and had problems connecting. The
ruby eventmachine loop quit unexpectedly so I tried to use the
RabbitMQ Java client to see if I had better luck with that library.
But also this library crashes when connecting to the broker.

I attached the error message I get from running one of the examples:

 > java -classpath

I get similar errors when trying to set up a connection with my own
Java code. Any ideas on what may cause this are greatly appreciated.
