解释演示层

The Java EE platform is a distributed multitiered application model that has three widely

javaee平台是一个分布式的多层应用程序模型，它有三个广泛的

used common tiers. These tiers are the presentation tier (or web tier), the business tier, and

使用通用层。这些层是表示层（或web层）、业务层和

the integration tier (or EIS tier).

集成层（或EIS层）。

The presentation tier, also known as the web tier, contains the components that create a

表示层，也称为web层，包含创建

web application. This tier has many components that use the HTTP protocol, construct

web应用程序。这个层有许多使用HTTP协议的组件，construct

views and interfaces for users, and provide a web service. These components are called web

为用户提供视图和接口，并提供web服务。这些组件称为web

components. There are two types of presentation tier:

组件。有两种类型的表示层：

Presentation-oriented tier: This type of presentation tier contains the

面向表示层：这种类型的表示层包含

components to construct an interactive web page and dynamic content using

组件来构造交互式网页和使用

HTML and XHTML. These components are JavaServer Faces technology, Java

HTML和XHTML。这些组件是JavaServer Faces技术，Java

Servlet technology, and JavaServer Page technology, which allow us to construct

Servlet技术和JavaServer页面技术，它们允许我们构造

an interactive web page.

一个交互式网页。

Server-oriented tier: This contains the components to construct an endpoint of a

面向服务器层：包含用于构造

web service. These components are JAX-RS and JAX-WS.

网络服务。这些组件是JAX-RS和JAX-WS。

The presentation-oriented tier is generally used on web applications using componentbased specifications such as JavaServer Faces technology, or web applications using actionbased Java Servlet technology as well as JavaServer Pages technology. The server-oriented
