Question

我有一个用例，其中请求被发送到代理A.然后它被克隆到两个不同的代理，即代理B＆amp;代理C.

代理B＆amp;必须在代理A的后序中捕获代理C.

这个逻辑会起作用吗？因为我收到了这个错误：

ort information from the /services/LIS/ URL.

对我有什么想法？

Answer 1

你的逻辑是正确的。如果此代理从jms队列中选择消息，请在克隆介体之前的inSequence中设置以下属性，然后重试。

<property name="messageType" value="text/xml" scope="axis2"/>

Answer 2

你的逻辑和代理conf是对的..问题是系统无法识别端点.. 您的服务网址是对的吗？你能这样做吗？（删除末尾的反斜杠）
