有关tomcat5.5.28的windows下的apr配置BUG,官方没有对应的tcnative-1.dll文件

今天启动tomcat5.5.28发现没有apr配置，报

[2010-04-20 17:33:19,734] [main] (AprLifecycleListener.java:99) DEBUG org.apache.catalina.core.AprLifecycleListener - The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: D:\Sun\jdk1.5.0_19\bin;D:\develop_tools\apache-tomcat-5.5.28\bin

错误，然后去官方下载最新的tcnative-1.dll文件1.1.14版本，(注：tomcat6.0.26自己带最新的1.1.20版本，所以启动没有问题),（官方没有介绍tomcat的版本和tcnative-1.dll版本的对应关系）

下载放入$tomcat_home/bin后报错信息如下:

?

这种情况极有可能是tomcat在升级的时候修改了AprLifecycleListener类的实现，但不敢确定，所以我挨个下了所有版本的tcnative-1.dll做实验，结果都会出现上述的两种异常；

然后我查看了tomcat5.5.28官方的的channellog,有如下收获

http://tomcat.apache.org/tomcat-5.5-doc/changelog.html这是连接地址

其中有涉及到

?

?	39997: Add the SSLRandomSeed option to the AprLifecycleListener to enable faster starts on development systems. (markt) ? 点进去看发现确实针对linux修改了东西. ? 最后我下载了tomcat5.5.27版本，在$TOMCAT_HOMT/bin里放入了tcnative-1.dll文件1.1.14版本 ? 启动一切正常，问题解决! ? ?
