tomcat 5.5 的The Apache Tomcat Native library which allows optimal performance 的解决

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:Javajdk1.5.0_05in;.;C:WINDOWSsystem32;C:WINDOWS;d: ubyin;.;..;D:Javajrockit-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/1.1.1/binaries/win32/tcnative-1.dll

将这个文件复制到C:WINDOWSsystem32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
