Subject: Re: Ruby- interactions with Appservers such as Oracle/Jboss

The forthcoming Pragmatic book "Enterprise Integration with Ruby" may
be helpful. The preview PDF doesn't discuss interfacing to EJB's, per
se, but it does go over options for communicating with non-ruby
systems.

Also, take a look at JSON (Javascript Object Notation:
http://www.json.org/), which is supported in many languages and is
becoming a popular & lightweight protocol for data passing, including
AJAX applications.

HTH,
