为什么呢？上网搜索了一下：

实际这是建议使用apache的apr;apr 是apache portable runtime 用上这个后可以有效的提高tomcat处理静态页面的能力.如果想使用apr的话， 实际操作很简单，

1.下载 http://tomcat.heanet.ie/native/1.1.1/binaries/win32/tcnative-1.dll 2.将 tcnative-1.dll文件放到你的jdk安装目录的bin文件夹下。比如我的jdk安装路径是：C:/Program Files/Java/jdk1.6.0_22；那么我就将tcnative-1.dll文件放到：C:/Program Files/Java/jdk1.6.0_22/bin下就行了。 3.重启Tomcat6可以看到，原来出现异常的地方变成如下提示信息： 信息: Loaded Apache Tomcat Native library 1.1.14.
