Configuring the Enterprise JavaBeans container

The Enterprise JavaBeans (EJB) container is a fundamental part of the Java Enterprise architecture. The EJB container provides the environment used to host and manage the EJB components deployed in the container. The container is responsible for providing a standard set of services, including caching, concurrency, persistence, security, transaction management, and locking services.

The container also provides distributed access and lookup functions for hosted components, and it intercepts all method invocations on hosted components to enforce declarative security and transaction contexts. Take a look at the following figure:

Configuring the Enterprise JavaBeans container

As depicted in this image, you will be able to deploy the full set of EJB components within WildFly:

Stateless session bean (SLSB): SLSBs are objects whose instances have no conversational state. This means that all bean instances are equivalent when they are not servicing a client.
Stateful session bean (SFSB): SFSBs support...
