我通过扩展org.apache.catalina.valves.ValveBase类并实现inovoke()方法为Apache Tomcat编写了一个Valve.现在我想将它添加到我的Tomcat中执行？请告诉我步骤.

我在具有CEP和APIM实例的服务器中运行BAM 2.4.0.我也用+2端口偏移运行它.但是当我启动BAM时,控制台打印:

[2014-03-06 16:34:04,126] ERROR {me.prettyprint.cassandra.connection.HConnectionManager} -  Could not start connection pool for host localhost(127.0.0.1):9160

目前我正在使用此代码将CSS资源添加到我的Wicket Web应用程序,

this.add(new CssResourceRefernce(FontAwesomeStyleSheetResourceReference.class, "css/font-awesome.css"));

我想将这个相同的CSS文件作为在线资源添加到我的应用程序中.使用HTML我可以这样做,

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.min.css" rel="stylesheet">

什么是"Wicket"执行此任务的方式？

我在WSO2 API Manager中更改了碳超级用户 - 管理员密码.在这之后我无法登录API Store.它说"无法登录你!权限不足".这里有什么问题？
