我想从 ActiveMQ 5.8.0 队列接收到 WSO2 ESB 4.6.0 中的代理的文本消息。这是我的代理定义：
<proxy xmlns="http://ws.apache.org/ns/synapse" name="proxy1" transports="jms" statistics="enable" trace="enable" startOnLoad="true">
<target>
<inSequence>
<property name="messageType" value="text/plain" scope="axis2"/>
<log level="full"/>
<drop/>
</inSequence>
</target>
<parameter name="transport.jms.ContentType">
<rules>
<default>text/plain</default>
</rules>
</parameter>
<parameter name="transport.jms.ConnectionFactory">myQueueConnectionFactory</parameter>
<parameter name="transport.jms.DestinationType">queue</parameter>
<parameter name="transport.jms.Destination">txqueue</parameter>
<description></description>
</proxy>
比我使用以下 Java 代码向队列发送短信：
QueueImpl queue = new QueueImpl("queue://txqueue");
Connection connection = createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer p = session.createProducer(queue);
Message msg = session.createTextMessage("Hello World");
p.send(msg);
这首先因 ClassNotFound 异常而失败。在我复制之后，来自activemq的hawtbuf-1.9.jar就消失了。（这是正确的方法吗？）
比我收到这个错误：

需要这方面的帮助，谢谢
编辑：
我在 Ubuntu 和 Windows 上都试过了，但都失败了。
我不知道它是否有区别，但我的 activemq 连接字符串是：
amqp:///test/?brokerlist='tcp://localhost:5672'
