The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:
Tomcat启动的时候出现下面这样的提示：

2006-1-26 19:44:11 org.apache.catalina.core.AprLifecycleListener lifecycleEvent
信息: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: D:\Java\jdk1.5.0_05\bin;.;C:\WINDOWS\system32;C:\WINDOWS;d:\ruby\bin;.;..;D:\Java\jrockit-R26.0.0-jdk


实际这是建议使用apache的apr。

如果想使用apr的话， 实际操作很简单，

下载 http://tomcat.heanet.ie/native/1.1.9/binaries/win32/tcnative-1.dll

将这个文件复制到C:\WINDOWS\system32\下面

然后重新启动tomcat，就会发现tomcat 的控制台信息为：
2006-1-26 19:48:42 org.apache.coyote.http11.Http11AprProtocol init
信息: Initializing Coyote HTTP/1.1 on http-9080
