Requirements of Enterprise Applications

The Java EE Platform:

• Is an architecture for implementing enterprise-class
applications
• Uses Java and Internet technology
• Has a primary goal of simplifying development of enterprise-
class applications through an application model that is:
– Vendor neutral
– Component based

Java EE Profiles

• Java EE 6 and 7 include profiles for application developers

that do not need the full Java EE Platform but require
application portability. Developers can choose between:
– The Java EE Web Profile: Focused on web applications and
supporting technologies
– The Java EE Full Platform: Complete Java EE application
servers
• Technically “Full Platform” is not a profile. The only profile
included in the Java EE specification is the web profile.
Additional profiles may be added in future releases.

Java EE Technology Specifications

The Java EE Platform is defined by a collection of Java

Specification Requests (JSRs). JSRs can be downloaded freely
from the Java Community Process (JCP) website.

Copyright © 2016, Oracle and/or its affiliates. All rights reserved. 1 - 15

Java EE Services and APIs

Some JSRs define only APIs, whereas others also define the
services that must be supplied by compatible implementations.
• APIs: These include a collection of classes, annotations, and
interfaces that developers can use. An API is packaged into a
library, which can be added to a Java application.
– JavaMail is an example of a downloadable library, which can
be added to any Java application.
• Services: JSRs may outline a required environment in which
the developer-supplied components will execute. A container
is a part of an application server, which supplies the required
runtime environment.
– Servlets are an example of components that require a (web)
container to execute.

Java EE Platform Tiers and Architecture

• The Java EE specification outlines an architectural model

based on tiers that developers are encouraged to use.
• The historical motivation for tiering:
– Division of labor around specialized servers
– Formal definitions of application responsibilities based on the
division of labor

N-Tier Architectural Model

EIS/Data
Presentation Business Integration
Client Tier (Resource)
Tier Tier Tier
Tier

The N-tier architectural model:

• Programmatically separates application functionality across
three or more tiers
• Has tier components and tier infrastructure that are uniquely
suited to a particular task
• Has programmatic interfaces that define the tier boundaries
