开源的FDS服务器替代品GDS

GDS服务器（Granite Data Services） 目前版本为0.4.0 RC1,下载地址为 http://www.graniteds.org/confluence/display/INTRO/Granite+Data+Services

该版本的特性如下：

• Full AMF3 support. See GDS AMF3 documentation.
• EJB3 services with transparent externalization mechanism and lazy initialized ActionScript 3 beans (Entity Beans / Hibernate). See EJB3 Services and Externalizers and Lazy Initialization.
• EJB3 Entity Bean to ActionScript 3 classes code generator. See AS3 Generation.
• Spring services. See documentation on Spring Services.
• POJO services (remote calls to simple Java classes that expose public methods). See Pojo Services.
• (planned) Data push. A Comet-like implementation with AMF3 data polling over HTTP (event/listener based architecture).
• (planned) Entity repository: a client side entity repository that ensures uniqueness (only one instance of each entity is present in the flash VM), weakness (only currently bound objects are kept in memory), and that acts as a services frontend (all server calls/events are managed by this central component). This will be loosely inspired by Cairngorm.
• (planned) Seam integration: a reliable GDS/Seam integration with full scopes (at least conversation) support.
• (planned) A set of Flex components suitable for complex data structures.

呵呵，还是很值得期待的哦！
