搞了好几天都不知道是什么原因，请大家帮帮我。谢谢了。
我就是把你的xml service名为Catalina3的http connector那段注释去掉 并且改了一下端口
service是多个connector和host(context)的组合，你的catalina3中只有ajp3，没有http并且你用http+ajp的那个端口去访问，会被ajp connector接受但是协议不用所以处理出错 自己找原因吧
把tomcat配置文件service.xml中的相关内容注解掉就可以了。

enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
查看一下是否有访问8009端口的程序。关闭这个程序或者换一个其他端口
port="8080" 是否被占用。
你贴出配置就能明显地找出错误你的协议用错了你应该用protocol的值应该是http\1.1(BIO),或者NIO具体类名我记不太清楚了回头到公司了再详细查查,一个CONTEXT可以使用多个CONNECTOR但端口不同，你配置的ajp协议占用了8080,再用http协议去访问肯定报错不是一个协议啊
将
connectionTimeout="20000"
redirectPort="8443" />
添加在service Catalina3中
哦！ 得将port换成其他的不能和在service名为Catalina的connector端口重复

不应该啊 邪门！
我也遇到同样的问题：java.lang.IndexOutOfBoundsException
原因是：
这没有配置或其docBase的路径指出错误。
同时访问时输入的端口不能是protocol="AJP/1.3"指定的端口，而是8080端口。
