Tomcat新手攻略
1、下载必要软件
①JDK 1.4.2
②Tomcat 4.0
2、配置环境
windows系统用户：
我的电脑------〉右键-------〉属性-------〉详细-------〉环境变数
path = x:\jdk1.4.2\bin
JAVA_HOME=x:\jdk1.4.2
CATALINA_HOME=x:\tomcat（这里有的是TOMCAT_HOME=x:\tomcat）
注：这里x为安装的驱动器。
这里要怎么设置取决于bin目录下的startup.bat文件。
我们可以在编辑状态下打开startup.bat，看究竟这个文件需要读取那个系统变量，我们就设置那个。比如当前我的版本tomcat的startup.bat文件内容如下：
@echo off
if "%OS%" == "Windows_NT" setlocal

我们可以清楚的看到这个文件需要读取系统变量CATALINA_HOME的值，所以我们在环境变数中把CATALINA_HOME设置为tomcat的安装路径就可以了。
3、启动、关闭tomcat
有2种方法可以启动、关闭安装好的tomcat：
① 直接点击运行bin目录下startup.bat和shutdown.bat文件就可以。
② 由于前面我们设置了path，所以我们直接在Dos窗口中直接键入startup或shutdown亦可。
4、设置虚拟目录
编辑server文件（x:\tomcat\conf\server.xml）
因为在tomcat启动时要读取server文件的信息，所以更改server文件后，一定要重新启动tomcat。
举个例子：
我们打算建立一个myJSP的虚拟目录，只要在server.xml文件中加入如下代码即可：
<Context path="/myJSP" docBase="c:\myJSP" debug="0"
reloadable="true" crossContext="true">
</Context>
其中，path为我们要建立的虚拟目录，docBase为实际目录在硬盘上的位置。
5、试我们前面工作的成果
编一个简单的小例子，来测试一下我们的虚拟目录是否可用。
refresh.jsp （c:\myJSP\refresh.jsp）
<%@page language="java"%>
<%@page import="java.util.Date"%>
<HTML>
<HEAD>
<TITLE>AUTO REFRESH</TITLE>
<%response.setHeader("refresh","5");%>
</HEAD>
<BODY bgcolor=#cc99dd><BR>
<center><h1>auto refresh example</h1></center><BR>
<center>refresh time : 5 sencords</center><BR>
<CENTER>Now Time is: <%=new Date()%></CENTER>
</BODY>
</HTML>
在地址栏键入http；//localhost:8080/myJSP/refresh.jsp，呵呵，看到效果了吧。
