如果你不幸装了NetBeans并且启用了外置的服务器，那么它会自动在你的web server的web.xml里添加一个filter，名叫HttpMonitorFilter。你用NetBeans时，它会过滤所有的http请求，这样NetBeans就可以显示所有的相关信息。但是如果不用NetBeans，比如我，用eclipse + Tomcat ，那就会得到这个异常：
NotifyUtil::java.net.ConnectException: Connection refused: connect

：
第一步. 删除 Tomcat目录中common\lib下的两个和netbeans有关的jar文件(以org-netbeans开头的)
第二步. 修改tomcat目录下的conf\web.xml，删除相关Filter的定义，就是这一段：
<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>127.0.0.1:8082</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>
