4、会，有如下界面：这是对java runtime environment的安装，单击“下一步”即可。安装结束后，会出现如下图界面，单击“关闭”按钮，结束安装。3、JDK的环境配置要配置的变量有：JAVA_HOME、CLASSPATH和PATH三个变量首先，在Windows系统下，右击“我的电脑”，从淡出的快捷菜单中选择“属性”，在弹出 的“属性”对话框中选择“高级”选项卡，单击“环境变量”按钮，在出现的界面中“系统变量”列表框下单击“新建”按钮，添加环境变量。出现下面界面：单击“新建”在变量名处，输入：JAVA_HOME,然后再变量值处填入下图的地址:includ已COPYRIGHTregist

24、he Software Foundation)的Jakarta项目中的一个核心项目，由Apache、Sun和其他一些公司及个人共同开发而成。由于有了 Sun的参与和支持，最新的Servlet和 JSP规范总是能在Tomcat中得到体现，Tomcat 5支持最新的Servlet 2.4和JSP 2.0规范。因为Tomcat技术先进、性能稳定，而且免费， 因而深受Java爱好者的喜爱并得到了部分软件开发商的认可，成为 日前比较流行的Web应用服务器。日前最新版本是7.0Tomcat很受广大程序员的喜欢，因为它运行时占用的系统资源 小，扩展性好，支持负载平衡与邮件服务等开发应用系统常用的功能； 而且

25、它还在不断的改进和完善中，任何一个感兴趣的程序员都可以更 改它或在其中加入新的功能。Tomcat是一个轻量级应用服务器，在 中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和 调试JSP程序的首选。(以上内容来源于百度百科)1. Java Servlet是指一个servlet就是Java编程语言中的一个类，它被用来扩展服务器的 性能，服务器上驻留着可以通过“请求-响应”编程模型来访问的应用程序。虽然servlet可 以对任何类型的请求产生响应，但通常只用来扩展Web服务器的应用程序。Java Servlet技 术为这些应用程序定义了一个特定于HTTP的servlet类。javax.s

26、ervlet和javax.servlet.http包为编写servlet提供了接口和类。所有的servlet都必须 实现Servlet接口，该接口定义了生命周期方法。当实现一个通用的服务时，您可以使用或扩展由Java Servlet API提供的GenericServlet 类。HttpServlet类提供了一些方法，诸如doGet和doPost，以用于处理特定于HTTP的服务.2. JSP技术有点类似ASP技术，它是在传统的网页HTML文件(*.htm,*.html)中插入Java程序段(Scriptlet)和JSP标记(tag)，从而形成JSP文件(*.jsp)。用JSP开发的Web应用是

27、跨平台的，即能在Linux下运行，也能在其他操作系统上运行。JSP技术使用Java编程语言编写类XML的tags和scriptlets，来封装产生动态网页的处理逻辑。网页还能通过 tags和scriptlets访问存在于服务端的资源的应用逻辑。JSP将网页逻辑与网页设计和显示分 离，支持可重用的基于组件的设计，使基于Web的应用程序的开发变得迅速和容易。3.2 Tomcat的下载输入网址：http:/tomcat.apache.org/ 进入界面:Apache Tomcat.
