我有一个关于海关经纪人的问题。
我使用此博客文章中的示例尝试了 Custom Broker 。我从“ https://dl.dropbox.com/u/17922825/blog/cep-ext-broker.zip
”
下载了一个示例模板自定义代理，我输入了.cep-broker-1.0-SNAPSHOT.jarCEP_HOME/repository/components/lib
接下来，我broker.xml输入CEP_HOME/repository/conf. 以下内容broker.xml：
<brokerTypes xmlns="http://wso2.org/carbon/broker"><br>
<brokerType class="org.test.cep.broker.TestBrokerTypeFactory"/><br>
</brokerTypes>
并且，重新启动并登录到管理控制台。
但是，我在管理控制台上访问了配置->代理->添加，每次我收到以下错误消息时都转储到监视器->系统日志中

此外，当我访问 Configure -> Broker -> List, Main -> CEP Buckets -> Add and List 时，我得到了同样的错误。
我使用 2.1.0 版的 WSO2 CEP。
如果我需要解释更多，我稍后会添加更多信息。
我恳求你帮助我。
