Aman, thank you for pointing this out. This is something I should have remarked on in the main article - I’ll update it in a second. The problem is that our internal codebase has moved on a little since RabbitMQ 1.3.0 was released, so there are actually two branches in the rabbitmq-stomp mercurial repository: default, which tracks the main branch of the server, and rabbitmqv130branch, which compiles against the released 1.3.0 release of the server.

The diff you’ve provided catches one of the three areas where the two stomp adapter differ; there are a couple of similar changes that need to be made.

Does it work out-of-the-box if, once you have performed your “hg clone” step, you run “hg update rabbitmqv130branch”, to switch to the maintenance branch, before compiling and running?

Just ran into a bug with the latest hg stomp adapter:

{”init terminating in doboot”,{{nocatch,{error,{cannotstartapplication,rabbit,{badreturn,{{rabbit,start,[normal,[]]},{’EXIT’,{{badmatch,{ok,{0,0,0,0},’rabbitstomplistenersup0.0.0.0:61613′}},[{rabbitstomp,startlisteners,1},{rabbitstomp,start,1},{rabbitstomp,kickstart,0},{rabbit,’-start/2-fun-0-’,1},{lists,foreach,2},{rabbit,start,2},{applicationmaster,startitold,4}]}}}}}}},[{init,startit,1},{init,start_em,1}]}}

Here’s a diff that fixes it:

Hey Tony,

That was it. There was one missing pkg (’erlang’ in Ubuntu Hardy) from my erlang installation. Thanks a lot!!

Are you sure you have a full Erlang installation, including Mnesia, available? The error message you’re getting seems to indicate it cannot find the mnesia:system_info function. Some operating systems package the OTP support libraries separately from the core Erlang runtime, so perhaps there is an additional package you could install.

I’m trying to run the adapter, but it’s crashing:


Erlang (BEAM) emulator version 5.5.5 [source] [64-bit] [async-threads:30] [kernel-poll:true]

Crash dump was written to: erlcrash.dump

Thank you!
