Granite Data Services 0.4.0 is available for download.
Granite Data Services (GDS) is a free, open source (LGPL'd), alternative to Adobe® LiveCycle® (Flex™ 2) Data Services for J2EE application servers. GDS implements services factory for EJB3 (Session beans that return Entity Beans), Spring and Pojo interactions.
This 0.4.0 release is mainly a bug fixes and compatibility release, with one new feature: a Jetty6+ based security service. While GDS is still in early development stage, you should be able to use the current 0.4 version in non-critical production environments.
