Question

控制台显示：
2011-3-10 7:23:13 org.apache.catalina.core.AprLifecycleListener init

请问怎么回事啊，那个validateJarFile错误，我检查过了，lib目录里面根本就没有Servlet.jar了啊

[url]http://tomcat.heanet.ie/native/1.1.3/binaries/win32/tcnative-1.dll[/url]
把上面的下载下来。不过是tomcat5.5的。
复制到 C:\apache-tomcat-5.5.23\bin 下面
这是tomcat建议你使用它的本地库 提高效率
