1. EJB 3 Services
Overview
EJB 3 technologies come with a very powerful framework for managing and securising enterprise services in an application server (session beans) as well as an efficient persistence and query language system (entity beans).
Granite Data Services gives you access to EJB 3 services via its org.granite.messaging.service.EjbServiceFactory for Session Beans methods calls, and fully supports entity beans serialization back to your Flex application, taking care of lazily loaded associations; both collections and proxies. EJB 3 entity bean support in GDS is covered in the sections about externalizers and lazy initialization, so this section will only discuss stateless and stateful session bean support.
The next subsections will introduce stateless and stateful session beans configuration with GraniteDS.
For a basic sample with GraniteDS and EJB 3 (stateless and stateful session beans, and entity beans) working together, download graniteds-ejb3-1.2.0.zip and import it as a new Eclipse project.
You may also have a look at the "Hello, world" Revisited tutorial for another basic sample application using EJB 3 technologies together with Granite Eclipse Builder.
