意思应该是 端口被占用啦！！但是 这个 问题 怎么解决！！ 关键是显示的是 好几个端口问题  不明白！ 一般也就一个8080端口的问题！这是怎么回事？？

Answer 2

首先进入Tomcat 6\conf\下..打开server.xml 找到一下代码部分
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
    <Connector className="org.apache.catalina.connector.http.HttpConnector"
               port="8080" minProcessors="5" maxProcessors="75"
               enableLookups="true" redirectPort="8443"
               acceptCount="10" debug="0" connectionTimeout="60000"/>
    <!-- Note : To disable connection timeouts, set connectionTimeout value 
     to -1 -->修改port="8080" 中的8080为你想修改的端口就可以拉..
严重: Parse error in application web.xml file at jndi:/localhost/TestMs/WEB-INF/web.xml
检查你的web.xml文件，可能存在问题！
把web.xml文件贴出来！

多谢大家帮忙！！我知道 问题在哪啦 ！！
在这里<servlet>
