JRuby/Rails by default uses ActiveRecords package for the purposes of Object Relational Mapping (ORM). JPA is a JavaEE ORM technology and the advantage of JPA is its pluggability. Modeling class and database migration in Rails is what Entity class and persistence provider does in JavaEE.
The TP2 of GlassFish V3 was released just before 2008 JavaONE and the default persistence provider of V3 is Eclipse Link. It'll be interesting to see how easy it is to use JPA in a classic blog rails application. Here is Ming's Blog demo application for GlassFish V3 (with MySQL) and Eclipse Link.TAGS: glassfish jruby rails v3 jpa
