Tomcat啟動的時候出現(xiàn)下面這樣的提示：

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

實際這是建議使用apache的apr。

如果想使用apr的話， 實際操作很簡單，

下載 http://tomcat.heanet.ie/native/1.1.1/binaries/win32/tcnative-1.dll

按照說明要求，將這個文件放到Tomcat下的bin目錄下

然后重新啟動tomcat，就會發(fā)現(xiàn)tomcat 的控制臺信息為：
2006-1-26 19:48:42 org.apache.coyote.http11.Http11AprProtocol init
信息: Initializing Coyote HTTP/1.1 on http-9080

詳情見 http://tomcat.apache.org/tomcat-5.5-doc/apr.html
