Tomcat4.0.1最近刚刚发布，关于它如何集成在Apache中连Jakarta.apache.org的网站上还没有类似的文章，作者一拿到Tomcat4.0，便想着如何将这两个绝妙组合搭配在一起，因为Tomcat4.1支持jsp1.2和Servlet2.3，如果只把Tomcat作为一般调试程序用的工具的话，没有必要将它和Apache放在一起，但是如果作为商业用途来用的话，它的功能还略显单薄，所以我们需要一个强有力的Web服务器，为此，我选择了Apache。下面我就将这两者怎样结合写出来。
一、需要的软件：
1、Jdk1.3，这是所有Java程序必须的软件包
2、Apache Web Server 1.3以上，在http://www.52jsp.com可以下载 1.3.22，笔者就用它。
3、Mod_jk，这是Jakarta组织开发的使Apache支持Tomcat的插件，比ApacheJserv更强大，因为ApacheJserv只能用在Apache上，而不能用在别的WebServer 上，Mod_jk可以和很多服务器搭配起来用。大家可以到
http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3/bin/win32/i386/处下载win32的mod_jk，也可以在http://www.52jsp.com下载。
4、Jakarta Tomcat4.0.1，这是Jakarta组织最新开发的支持Servlet2.3和jsp1.2的服务器。大家可以到http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.1/bin/ 处下载。
5、Jdk1.3，这是所有都必须的
二、安装：
1、安装Jdk，我将它安装到e:\jdk1.3下
2、安装Apache,安装它没有什么可说的，一路回车，不要忘了记住它的安装路径，我安装在E:\apache下。
3、安装Mod_jk，只要将下载的mod_jk.dllcopy到安装Apache目录下的libexec下就可以了。
4、安装Tomcat,下载的Win32版本是一个exe文件，没什么可说的，我将它安装在E:\Apache Tomcat 4.0这个目录下。
三、 配置
1、 首先，配置Jdk1.3,在你的环境变量里将JAVA_HOME设为E:\jdk1.3,具体做法为，WinNT/2000: 我的电脑?>属性?>高级?>环境变量，增加一个，值设为E:jdk1.3。如果为Win9X,那么手动修改Autoexec.bat增加Set JAVA_HOME=E:\jdk1.3，重启机器使设置生效。
2、 配置Apache，修改Httpd.conf，增加的内容如下：
LoadModule jk_module libexec/mod_jk.dll
AddModule mod_jk.c
JkWorkersFile "E:\Apache Tomcat 4.0\conf\workers.properties"
JkLogFile logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
对于上面的配置我简单介绍一下，JkWorkersFile使指定mod_jk工作所需要的工作文件，JkMount后面是将所有和jsp和servlet的请求通过Apj13的协议送给Tomcat，让Tomcat来处理。
3、 在E:\Apache Tomcat4.0\conf目录下建一个worker.properties,如果你要是用过Tomcat3.2以上，将它里面的workers.properties拷贝过来也可以，但是要做相应的修改,workers.properties内容如下：
# $Header: /home/cvs/jakarta-tomcat/src/etc/Attic/workers.properties,v 1.3.2.2 2000/10/16 01

# workers.properties -
#
# This file provides jk derived plugins with with the needed information to
# connect to the different tomcat workers.
#
# As a general note, the characters $( and ) are used internally to define
# macros. Do not use them in your own configuration!!!
#
# Whenever you see a set of lines such as:
# x=value
# y=$(x)something
#
# the final value for y will be valuesomething
#
# Normaly all you will need to modify is the first properties, i.e.
# workers.tomcat_home, workers.java_home and ps. Most of the configuration
# is derived from these.
#
# When you are done updating workers.tomcat_home, workers.java_home and ps
# you should have 3 workers configured:
#
# - An ajp12 worker that connects to localhost:8007
# - An ajp13 worker that connects to localhost:8009
# - A jni inprocess worker.
# - A load balancer worker
#
# However by default the plugins will only use the ajp12 worker. To have
# the plugins use other workers you should modify the worker.list property.
#
#
#
# workers.tomcat_home should point to the location where you
# installed tomcat. This is where you have your conf, webapps and lib
# directories.
#
workers.tomcat_home=E:\Apache Tomcat 4.0
#
# workers.java_home should point to your Java installation. Normally
# you should have a bin and lib directories beneath it.
#
workers.java_home=e:\jdk1.3
#
# You should configure your environment slash... ps= on NT and / on UNIX
# and maybe something different elsewhere.
#
ps=\
# ps=/

#

#

#
对于这个文件，大家要修改只有两个地方，一个是workers.tomcat_home，这是指定Tomcat工作的目录，另外一个是workers.java_home，这是指定Jdk的目录，大家可以做适当修改。
4、 配置Tomcat，这可是比较重要的一步，成败在此一举。
大家打开Tomcat的核心配置文件E:\Apache Tomcat4.0\conf\server.xml
修改如下：
将<!-- Define an AJP 1.3 Connector on port 8009 -->
<!--
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8009" minProcessors="5" maxProcessors="75"
acceptCount="10" debug="0"/>
-->
的<!-- --> 去掉，这句话熟悉XML的人都知道它是注释，因为默认的Tomcat4是没有启用Apj13的8009的端口即mod_jk所使用，修改后如下：
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8009" minProcessors="5" maxProcessors="75"
acceptCount="10" debug="0"/>
然后保存，现在你的Tomcat和Apache的配置基本完成了。下面我们开始测试。
四、 测试:
大家首先启动Apache，然后在浏览器里输入http://localhost，如果能看到Apache的欢迎页面，那么恭喜您，第一步成功了。然后回到Tomca目录下运行startup.bat启动Tomcat，再打开浏览器输入：http://localhost:8080/ 如果看到可爱的Tomcat，那么恭喜您，Tomcat也没有问题，最后最重要的是Apache下可以解释jsp和Servlet,把下面的代码copy到文本编辑器中命名为hello.jsp,内容如下:
<%@ page contentType="text/html;charset=gb2312"%>
<html>
<body>
<%String str="Hello World!";%>
<%str=str+"你好";%>
<%=str%>
</body>
</html>
将它保存到E:\Apache\htdocs下，然后在浏览器里输入http://localhost/hello.jsp
如果看到了Hello,那么您的确成功了，完成了通向jsp和servlet的第一步。
