GDS Ships FOSS Alternative to Adobe LiveCycle DS
Granite Data Services (GDS) is a free, open source (LGPL'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 benefits.
Following two release candidates, the final Granite Data Services 1.0.0 release is now available for download on Sourceforge. Documentation has been updated and now covers all new features available in GDS 1.0. Browse it here.
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.
