This project contains custom Hibernate and JRuby extensions to let Hibernate work directly with org.jruby.RubyObject objects. That means that the Hibernate session accepts and returns plain old Ruby objects (no intermediary Java domain classes are needed). Another goal is to provide a Rubyish interface to the Hibernate configuration and functionality.
The idea to start this project comes from Ola Bini's blog http://ola-bini.blogspot.com/2007/04/activehibernate-any-takers.html. For more details please see http://rubymatic.blogspot.com.
There is no formal release yet, only code in the Subversion repository.
