Question

我有Synapse配置来从Oracle JMS队列中读取消息，调用Web服务并捕获日志中的响应。配置基于ws02 with oracle

我试图扩展配置以捕获另一个Oracle quueue中的响应，但是我收到如下错误。看起来，尽管将回复目的地类型指示为“队列”，他仍然在尝试创建主题会话而不是队列会话。

我想我发现了这个问题。看起来Oracle JMS与Axis2 jms传输库不兼容。

JMSOutTransportInfo(JMSConnectionFactory jmsConnectionFactory, Destination dest,
        String contentTypeProperty) {
    this.jmsConnectionFactory = jmsConnectionFactory;
    this.destination = dest;
    destinationType = dest instanceof Topic ? JMSConstants.DESTINATION_TYPE_TOPIC
                                            : JMSConstants.DESTINATION_TYPE_QUEUE;
    this.contentTypeProperty = contentTypeProperty;
}

为了确定目标是主题还是队列axis2，jms首先检查目标是否实现了Topic接口。问题是，Oracle类对于Topic和Queue都是相同的，AQjmsDestination同时实现了Topic和Queue接口。

在synapse中发送对jms队列的回复
