我想在WSO2 CEP上使用JMS创建自定义代理。我创建了两个类，NewJMSBrokerType和NewJMSBrokerTypeFactory。
我为NewJMSBrokerType扩展了JMSBrokerType，并为NewJMSBrokerTypeFactor实现了JMSBrokerTypeFactory。
我将broker.xml放入CEP_HOME/repository/conf。
以下broker.xml的内容：
<brokerTypes xmlns="http://wso2.org/carbon/broker">
<brokerType class="org.wso2.broker.new_jms.NewJMSBrokerTypeFactor"/>
</brokerTypes>
最后，我重新启动CEP服务器，在控制台上转储了错误消息。

我恳请你帮助我。
答案 0 :(得分：0)
您无法扩展JMSBrokerType和JMSBrokerTypeFactory，因为它们是不允许通过OSGI服务公开的内部Java类...您只能扩展BrokerType和BrokerTypeFactory以创建自定义类..
此致
