问题 单项选择题

以下关于J2EE平台技术的叙述中,错误的是()。

A.J2EE平台采用多层次分布式的应用模式

B.J2EE中EJB组件是客户端组件

C.J2EE应用可以不基于Web

D.J2EE组件使用Java编程语言编写

答案

参考答案:B

解析:

[分析]: 本题考查J2EE平台方面的基础知识。

J2EE平台采用多层次分布式的应用模式,应用逻辑根据功能被划分成组件,组成J2EE应用的不同应用组件安装在不同的服务器上。

J2EE规范定义了如下J2EE组件:

•应用(Application)客户端和小程序(applet)是客户端组件;

•Java Servlet和Java Server Pages技术组件是Web组件;

•Enterprise JavaBeans (EJB)组件是业务组件;

一个J2EE应用可以基于Web或不基于Web。对于不基于Web的J2EE应用,一个应用客户端软件将运行在客户端机器上,而对于基于Web的J2EE应用,浏览器会下载Web页面和小程序(applet)到客户端机器上。

J2EE组件使用Java编程语言编写,也像任何Java程序一样编译。

      How would you like an easy way to earn $2,500? All you have to do is to sit around and wait for your

meals. There's a catch, however. You have to stay in a chicken cage with a stranger for a whole week.

There are no books or television or radio for amusement. You can't leave until the week is up. And a camera

will be recording your every move.

     Two people actually took the job. The idea came from Rob Thompson, a video artist. He wanted to make

a film about the way animals are treated. His goal was to raise people's awareness of the living conditions of

animals that are raised for food. He decided to pay $5,000 out of his own savings to two people who were

willing to live like chickens for a week. 

     To Rob's surprise, quite a few people answered his advertisement. He had interviews and selected Eric,

a 24-year-old restaurant worker, and Pam, a 27-year-old chemist. The plan was for them to spend seven days

together in a chicken cage that was six feet long and three feet wide. A camera would record their experience,

which would take place in an art museum. 

     The week was long and difficult. They slept on a hard wooden floor. They couldn't stand up without

banging their heads. They ate vegetables and drink water from a garden hose-pipe (橡胶软管). Their only

privacy was a toilet surrounded by a curtain. There were no sinks, mirrors, or toothbrushes in the cage. Their

only inspiration was the two framed checks that hung on the wall outside the cage. Visitors who came here

were warned, "Do not feed the humans."

      Finally it was over, and Pam and Eric came out of the cage. They had survived the week, and they each

had a $2,500 check in their hands. When Rob Thompson opened the cage, Eric came out, changed into clean

clothes, and ate a chocolate bar right away. "It's great for me to be able to stand up." he said. Pam just

changed her clothes and left. After a week of visitors and reporters watching her, she didn't want to talk to

anyone.
