参考了网上很多资料，发现大都或多或少有些小问题，现把我的整合过程贴出来，供大家参考。
一、准备
需要以下程序：
j2sdk1.4.2_01,apache-2.0.47,jakarta-tomcat-4.1.27,以及mod_jk2-2.0.43.dll
以上程序都可以在sun和apache.org下载到。
j2sdk1.4.2_01 : http://java.sun.com/j2se/1.4.2/download.html选j2se v 1.4.2_01 的sdk
apache-2.0.47 : http://apache.linuxforum.net/dist/httpd/binaries/win32/apache_2.0.47-win32-x86-no_ssl.exe
tomcat-4.1.27 : http://apache.linuxforum.net/dist/jakarta/tomcat-4/binaries/jakarta-tomcat-4.1.27.exe
mod_jk2-2.0.43.dll : http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/release/v2.0.2/bin/win32/mod_jk2-2.0.43.dll
注意下载的jk2文件名：mod_jk2-2.0.43.dll，而网上还有mod_jk-2.0.4x.dll，这是jk而不是jk2
二、安装
假设j2sdk1.4.2_01安装到d:\j2sdk1.4.2_01下，用[java_install_dir]代表此路径
apache-2.0.47安装到d:\program files\apache group\apache2，用[apache_install_dir]代表此路径，服务端口为80
jakarta-tomcat-4.1.27安装到d:\program files\apache group\tomcat 4.1，用[tomcat_install_dir]代表此路径，服务端口为8080
在系统环境变量里添加java_home和tomcat_home分别为以上路径，再修改class_path，添加%java_home%\lib;%tomcat_home%\bin;
安装时把apache和tomcat都设置为后台服务方式运行。
三、配置
1. 在apache2中安装mod_jk2-2.0.43.dll
将mod_jk2-2.0.43.dll拷贝到[apache_install_dir]/modules目录中
编辑[apache_install_dir]/conf/httpd.conf配置文件，在文件最后添加如下一行：
loadmodule jk2_module modules/mod_jk2-2.0.43.dll
2. 配置apache端
[在apache_install_dir]/conf目录中新建文件workers2.properties，内容如下：
# define the comunication channel
[channel.jni:jni]
info=the jni channel, used if tomcat is started inprocess
# define the parameters for the java virtual machine
[vm:]
info=parameters used to load a jvm in the server process
opt=-djava.class.path=[tomcat_install_dir]\bin\tomcat-jni.jar;[tomcat_install_dir]\bin\tomcat.jar
opt=-dtomcat.home=[tomcat_install_dir]
opt=-dcatalina.home=[tomcat_install_dir]
opt=-xmx128m
# jni worker startup handler
[worker.jni:onstartup]
info=command to be executed by the vm on startup. this one will start tomcat.
class=org/apache/jk/apr/tomcatstarter
arg=start
stdout=[apache_install_dir]\logs\stdout.log
stderr=[apache_install_dir]\logs\stderr.log
# jni worker shutdown handler
[worker.jni:onshutdown]
info=command to be executed by the vm on shutdown. this one will stop tomcat.
class=org/apache/jk/apr/tomcatstarter
arg=stop
# map the tomcat examples webapp to the web server uri space
[uri:/examples/*]
info=map the whole webapp
#注：
#网上有资料opt=-djava.class.path是指向\lib\，实际上安装目录下并无\lib目录，如不修改会出现java.lang.noclassdeffounderror: org/apache/jk/apr/tomcatstarter异常
#把[tomcat_install_dir]和[apache_install_dir]换成实际安装路径，其余不用做任何改动
3. 配置tomcat端
修改[tomcat_install_dir]/conf/jk2.properties，用以下内容替换原来内容：
# set the desired handler list
handler.list=apr,request,container,channeljni
# enable jni use channeljni directive
apr.jnimodeso=[apache_install_dir]\modules\mod_jk2-2.0.43.dll
# if set to inprocess the mod_jk2 will register natives itself
# this will enable the starting of the tomcat from mod_jk2
# if you wish to start the tomcat from inside web server then
# you don′t need any above directive. here is shown the default
# value for the apr that you can ommit
apr.jnimodeso=inprocess
#注：
#把[tomcat_install_dir]和[apache_install_dir]换成实际安装路径，其余不用做任何改动
#这种方式使用jni通道，因此运行apache时会通过jni直接在后台启动tomcat。
四、测试：
启动apache
看http://localhost/examples/jsp/
如显示正确内容则整合成功！
如不成功请检查[apache_install_dir]\logs\stdout.log和[apache_install_dir]\logs\stderr.log日志，看是什么错误，根据错误提示进行修改。
