Granite Data Services (GDS) is a free, open source (LGPL [1]'d), alternative to Adobe® LiveCycle® (Flex™ 2+) Data Services for J2EE application servers. It is not, however, a drop-in replacement: you won't be able to simply deploy a LiveCycle Data Services application into a Granite Data Services server without modifications. The main goal of this project is to provide a framework for Flex 2/EJB3/Spring/Seam/Guice/Pojo application development with full AMF3/RemoteObject [2] benefits.

Following two release candidates, the final Granite Data Services 1.0.0 release is now available for download on Sourceforge [3]. Documentation has been updated and now covers all new features available in GDS 1.0. Browse it here [4].

Here is a brief list of the main changes since the 0.4 version:

• Data Push (Gravity): this new feature is implemented as AMF3 data sent over HTTP (Comet, freely based on the Bayeux protocol).
• Spring integration is now complete with full support of Acegi security.
• Seam integration is new and experimental feature in GDS 1.0. A sample application is available.
• Guice/Warp integration is new and experimental feature in GDS 1.0. A sample application is also available.
• Gas3 (the ActionScript3 code generator) gives better performance and brings support for Java Enum types and all kind of Ejb3.
• Flex3 beta3 compatibility: GDS 1.0 is fully compatible with Flex3 beta3.

Complete release notes are available in documentation.
