The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:

今天下载Windows安装版的tomcat5.5,安装完以后启动时候出现:

The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: ......

意思是说在产品环境下可以优化工作性能的Tomcat的本地包没有找到。

Google了一下,原来Tomcat从5.5版本后增加了APR技术(Apache Portable Runtime),这是一个用C语言写成文件包,目的在于提高Tomcat的服务性能,从而使得Tomcat将不仅仅担任一个容器的功能,而是要成为一个一般的web服务器(general purpose webserver)。 所以按照上面的提示,下载了tcnative-1.dll文件,放入上面提示所列出的java.library.path中的任意一个里面,结果又出现下面的错误:

严重: An incompatible version 1.1.1 of the Apache Tomcat Native library is installed, while Tomcat requires version 1.1.3

意思是说刚才下的版本过低,需要下载一个更高高版本的。

具体下载地址:tomcat.heanet.ie/native/

里面列出了1.1.0-1.1.9所有版本的链接地址!随便下载一个高于1.1.3版本的替换掉刚才文件就可以,既然有高版本的,当然下最新的喽~~

我下载的是1.1.9 替换掉以后再次启动tomcat会出现:

org.apache.coyote.http11.Http11AprProtocol init 

这样就说明我们刚才成功了~~ 庆祝一下!

顺便附上各个版本tcnative-1.dll文件的下载地址,省的麻烦~~---->
