Granite Data Services
Granite Data Services (GDS) is an open source, event-driven, free, platform-independent, enterprise-grade alternative to Adobe LiveCycle (Flex 2) Data Services for J2EE (Java 2 Platform, Enterprise Edition) application servers.
Features at a glance
Key features include Tide, a client development framework, powerful code generation tools, support for cross client Java technologies, easy configuration, integration with cross-platform Java EE frameworks, as well as Gravity, a powerful real-time module.
The project has been designed to offer full AMF3 (Action Message Format) support, as well as an EJB3 Entity Bean to ActionScript 3 classes code generator utility. It comes with built-in support for all mainstream operating system, as well as some of the most popular languages.
Granite Data Services also features a Comet-like Data Push implementation (AMF3 requests sent over HTTP). It can be easily used by thousands of companies for critical applications, supports powerful cross client technologies, including Oracle JavaFX, Google Android and Apache Flex.
Integrates well with all Java EE application servers
Another interesting feature is the ability to integrate well with all major Java EE frameworks, application servers and JPA engines, including Apache Tomcat, DataNucleus, JBoss, Jetty, Spring, GlassFish, WebSphere, EJB, Hibernate, WebLogic, CDI, EclipseLink, Seam and OpenJPA.
Not a drop-in replacement for Adobe LiveCycle
Granite Data Services is not, however, a drop-in replacement, as you won't be able to simply deploy a Flex 2 Data Services application into a Granite Data Services server without modifications.
Under the hood and supported OSes
It is written entirely in the Java programming language, which means that it’s supported on all operating systems where the JRE (Java Runtime Environment) is available, including all GNU/Linux distributions, as well as the Microsoft Windows and Mac OS X operating systems. It has been successfully tested with both 32-bit (x86) and 64-bit (x86_64) instruction set architectures.
