在ESB WSO2中使用克隆中介程序时无法返回in out序列

我在DZONE博客上举了一个克隆中介的例子，但看起来我犯了一些错误，无法返回，无法进一步处理

有人能帮忙吗

  <proxy name="DSS_TrainDetailsProxy" transports="http" startOnLoad="true" trace="disable" statistics="enable">
    <target inSequence="DSS_TrainDetails_IN" outSequence="DSS_TrainDetails_OUT" faultSequence="CommonFaultHandler"/>
    <publishWSDL key="DSS_TrainDetails_wsdl"/>
</proxy>
 <localEntry key="DSS_TrainDetails_wsdl" src="file:repository/conf/train/wsdl/TrainDetails.wsdl"/>

<sequence name="DSS_TrainDetails_IN">
 <clone>
     <target>
        <send>
            <endpoint key="DSS_TrainDetails_EPR"/>
        </send>
    </target>
    <target>
        <send>
            <endpoint key="DSS_TrainDetails_EPR"/>
        </send>
    </target>
    <target>
        <send>
            <endpoint key="DSS_TrainDetails_EPR"/>
        </send>
    </target>
</clone>

尝试：删除代理定义中的outSequence=“DSS\u TrainDetails\u OUT”并在克隆目标内部，将

更改为

Hi只是想让您知道克隆中介为我工作：）我已按顺序更改了以下代码我已按顺序从中删除了“send”关键字：

<sequence name="DSS_TrainDetails_IN">
 <clone>
     <target>
            <endpoint key="DSS_TrainDetails_EPR"/>
    </target>
    <target>
            <endpoint key="DSS_TrainDetails_EPR1"/>
    </target>
    <target>
            <endpoint key="DSS_TrainDetails_EPR2"/>
    </target>
</clone>

<sequence name="DSS_TrainDetails_IN">
 <clone>
     <target>
            <endpoint key="DSS_TrainDetails_EPR"/>
