 - javax.ejb.Stateful
|
| *[EJB 3.1 Singleton|Singleton Example]* | Shows two EJB 3.1 *@Singleton* beans.  One configured to load on startup via *@Startup* and using Bean-Managed Concurrency and synchronization.  Another using Container-Managed Concurrency via *@Lock(READ)* and *@Lock(WRITE)*.  |   - javax.annotation.PostConstruct

|
| *[EJB 2.1 Compatibility|EJB 2.1 Compatibility Example]* | Shows an EJB 3.0 Stateful bean with Business interfaces and EJB 2.1 interfaces (now called "component" interfaces) using the *@LocalHome* and *@RemoteHome*. Four interfaces in total. |  - javax.ejb.CreateException

 - javax.ejb.Local
 - javax.ejb.Remote
 - javax.ejb.Stateful
|
| *[Injection of env-entry 2|Custom Injection]* | Same as the above example but shows how to use a *properties file* to declare the injection values and demonstrates how to get injection of *more types* such as java.util.Date, java.lang.Class, java.net.URI and more.  _OpenEJB specific feature_. |  - javax.annotation.Resource
 - javax.ejb.Stateless

|
| *[Injection of EntityManager|Injection of EntityManager Example]* | Shows use of *@PersistenceContext* to have an *EntityManager* with an *EXTENDED* persistence context injected into a @Stateful bean.

 - javax.ejb.TransactionAttributeType.REQUIRES_NEW
 - javax.persistence.Entity
 - javax.persistence.EntityManager
 - javax.persistence.PersistenceContext
 - javax.persistence.PersistenceContextType.TRANSACTION
 - javax.persistence.Query
|
| *[Testing Security|Testing Security Example]* | Builds upon the [Injection of EntityManager Example] but adds the use of *@RolesAllowed* and *@PermitAll* in the @Stateful bean to restrict who can perform create, persist and remove operations on the EntityManager.  Shows a TestCase using the *@RunAs* annotation to execute and test the bean code as various users. |  - javax.annotation.security.PermitAll
 - javax.annotation.security.RolesAllowed
 - javax.annotation.security.RunAs
 - javax.ejb.EJBAccessException
 - javax.ejb.Stateful
 - javax.ejb.Stateless

 - javax.persistence.EntityManager
 - javax.persistence.PersistenceContext
 - javax.persistence.PersistenceContextType.EXTENDED
 - javax.persistence.Query
|
| *[Embedded and Remotable]* | Demonstrates how to use an OpenEJB feature that allows people embedding OpenEJB into their applications to support remote clients in other VMs.  This is not required for unit testing. |  - javax.ejb.Remote
 - javax.ejb.Stateful
|
| *[Helloworld Weblogic]* | Demonstrates OpenEJBs ability to understand and support the WebLogic deployment descriptors so people using that platform in production can still use OpenEJB in their IDE or build to unit test their EJB applications. |  - javax.ejb.CreateException
 - javax.ejb.EJBLocalHome
 - javax.ejb.EJBLocalObject
 - javax.ejb.LocalHome
 - javax.ejb.Stateless
|
