原因：8080端口被占用,在dos下运行“netstat -a ”查看当前端口的使用情况。

解决方法：修改Tomcat的使用端口，具体做法——找到目录...\Tomcat 5.5\conf，在conf目录下有“server.xml”文件，用记事本打开此文件，查找（打开文件后Ctrl+F）文件中的所有“8080”，并改为其他没有被占用的端口值（如：8088、8081等）。

Tomact等工具都是刚刚安装上的，怎么会被占用呢，还没有想通！

附：什么是tomcat 80端口？

tomcat是一个JAVA虚拟机软件，用于提供WWW服务。www服务的默认端口就是80，所以，tomcat的端口也是80.这个是可以修改的。好处就是，80端口是默认的www服务端口，要是修改成别的，就必须在IP后面加上这个端口才可以访问你的IIS.比如：http://192.168.0.1:8080.
