Camel-like integration component for Ruby

Question

Hi,

I'm in need to get some integration work done in my ruby application. My main focus is web services and ActiveMQ integration (the systems I'm going to connect to are mainly written in Java).

I was wondering if there's something that resembles the capabilities of Camel in Ruby? All I need is something that'll let me define routing between incoming data from those sources I mentioned above, do some pre-processing and post them back somewhere else.

Thanks, Matthias
