NetBeans HTTP Monitor 报错的问题

安装了Netbeans以后，启动Tomcat老是会报WARNING *********** NetBeans HTTP Monitor ************ 这样的错误。
原来是在Tomcat的web.xml中添加了一个filter，注释掉就可以了。
记住以后用Netbeans的Http Monitor的时候要放开


  <filter>
    <filter-name>HTTPMonitorFilter</filter-name>
    <filter-class>org.netbeans.modules.web.monitor.server.MonitorFilter</filter-class>
    <init-param>
      <param-name>netbeans.monitor.ide</param-name>
      <param-value>localhost:8086</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>HTTPMonitorFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>
