WSO2服务链接-代理服务

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和代理C

代理B和代理C的响应必须在代理A的结果中捕获

这个逻辑行得通吗？因为我得到了这个错误：

对我有什么想法吗

您的逻辑和代理配置是正确的。问题是系统无法识别端点。。 您的服务URL正确吗？ 你能这样做吗？（删除末尾的反斜杠）

你的逻辑是正确的。 如果此代理正在从jms队列中拾取消息，请在克隆中介之前的插入序列中设置以下属性，然后重试

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

你好，拉塔，我也试过了。它不起作用。还有其他解决办法吗Guruth导致上述问题的原因是，未正确定义传输发送方，或者端点url错误..顺便说一句，您从类中介器获得的输出是什么..？类中介器返回字符串Ratha。还有我的运输寄件人遗漏了什么。我猜不出还有什么：（在克隆之前、类中介之后放一个log=full，粘贴soap消息并检查头值。

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