• Container-managed transactions ( CMT ) are by default active for calls to session beans.
• JNDI names for EJB session beans are assigned by the EJB container via the following scheme:
• The name " conversational " is used as in this state the client interacts with the bean-a stateless session bean does not do so.
• To support JAX-WS, the session bean is annotated with the @ WebService annotation, and methods that are to be exposed remotely with the @ WebMethod annotation ..
• An example usage of the session layer is session beans, which are only active as long as the session is active, and are deleted when the session is disconnected.
• Stateless-and Singleton session beans may also expose a " web service client view " for remote communication via WSDL and SOAP or plain XML . This follows the JAX-RPC and JAX-WS specifications.
• Java programs running in the WAS z / OS environment wishing to be the target of an invocation from outside must implement the OLA interface in a stateless session bean using the OLA class files supplied in the development tooling support.
• In Java Platform, Enterprise Edition ( Java EE ), the "'Conversational state "'are the field values of a session bean plus the transitive closure of the objects reachable from the bean's fields.
• Although the EJB specification does not mention exposure as RESTful web services in any way and has no explicit support for this form of communication, the JAX-RS specification does explicitly support EJB . Following the JAX-RS spec, Stateless-and Singleton session beans can be root resources via the @ Path annotation and EJB business methods can be mapped to resource methods via the @ GET, @ PUT, @ POST and @ DELETE annotations.
