Answer :

A deployable unit that consists of one or more enterprise beans and an EJB deployment descriptor.


Question 32 :

What is EJB object ?

Answer :

An object whose class implements the enterprise bean's remote interface. A client never references an enterprise bean instance directly; a client always references an EJB object. The class of an EJB object is generated by a container's deployment tools.


Question 33 :

What is EJB server ?

Answer :

Software that provides services to an EJB container. For example, an EJB container typically relies on a transaction manager that is part of the EJB server to perform the two-phase commit across all the participating resource managers. The J2EE architecture assumes that an EJB container is hosted by an EJB server from the same vendor, so it does not specify the contract between these two entities. An EJB server can host one or more EJB containers.

What is EJB server provider ?

Answer :

A vendor that supplies an EJB server.
