117. What is J2EE

118. What is J2EE application
Any deployable unit of J2EE functionality. This can be
a single J2EE module or a group of modules packaged
into an EAR file along with a J2EE application
deployment descriptor. J2EE applications are typically
engineered to be distributed across multiple computing
tiers.
119. What is J2EE component
A self-contained functional software unit supported by
a container and configurable at deployment time. The
J2EE specification defines the following J2EE
components: Application clients and applets are
components that run on the client. Java servlet and
JavaServer Pages (JSP) technology components are Web
components that run on the server. Enterprise
JavaBeans (EJB) components (enterprise beans) are
business components that run on the server. J2EE
components are written in the Java programming
language and are compiled in the same way as any
program in the language. The difference between J2EE
components and "standard" Java classes is that J2EE
components are assembled into a J2EE application,
verified to be well formed and in compliance with the
J2EE specification, and deployed to production, where
they are run and managed by the J2EE server or client
container.
120. What is J2EE module
A software unit that consists of one or more J2EE
components of the same container type and one
deployment descriptor of that type. There are four
types of modules: EJB, Web, application client, and
resource adapter. Modules can be deployed as
stand-alone units or can be assembled into a J2EE
application.
