原因：catalina.jar中means包是空的，具体该类的作用是配置JMX下

JMX（Java Management Extensions，即Java管理扩展）是一个为应用程序、设备、系统等植入管理功能的框架。JMX可以跨越一系列异构操作系统平台、系统体系结构和网络传输协议，灵活的开发无缝集成的系统、网络和服务管理应用。

解决办法：

把server.xml中的<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />注释掉就可以了

<!--<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" /> -->

当然，如果你是少了jar，也可以把jar添加进去就搞定。

如果你是我下面这种情况，可以考虑注释掉，也可以考虑把Tomcat7原有的Listener替换掉当前的Listener就行

这次错误是我把Tomcat6的server.xml文件拷贝的Tomcat7下面来，想着懒得复制内容，干脆直接复制文件，没想到这个懒不能偷！

在Tomcat6的catalina.jar中有org.apache.catalina.mbeans.ServerLifecycleListener这么个类：

而Tomcat7中则木有这个类：

并且Tomcat7的server.xml跟Tomcat7的server.xml中的Listener都不相同，在Tomcat7中并没有org.apache.catalina.mbeans.ServerLifecycleListener这个Listener。

Tomcat6的server.xml：

 

<Server port="8005" shutdown="SHUTDOWN">

  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener" />
  <!-- JMX Support for the Tomcat server. Documentation at /docs/non-existent.html -->
  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

Tomcat7的server.xml：

<Server port="8003" shutdown="SHUTDOWN">
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
