通过 wso2 esb 中的计划任务的代理服务运行出现错误 "Unexpected error sending message back"

Question

我们已经在 eclipse 中使用 esb 项目在 wso2 esb 中创建了一个代理服务。此代理服务正在调用 2 个 Web 服务，第一个是从遗留系统查询数据，另一个是在 oracle fusion 中创建销售订单。

当运行 from soap ui 成功执行并创建销售订单时，此代理服务没有错误。当运行来自计划任务时，它运行并创建订单但在 wso2carbon.log 文件中给出错误 "Unexpected error sending message back {org.apache.synapse.core.axis2.Axis2Sender}"。

定时任务xml如下

<task class="org.apache.synapse.startup.tasks.MessageInjector"
        group="synapse.simple.quartz" name="testtask2">
        <trigger count="1" interval="60"/>
        <property name="proxyName" value="EslSfaOFAOMSOIntegrationPS" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="soapAction" value="operation" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="injectTo" value="proxy" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="to"
            value="http://10.1.6.176:8280/services/EslSfaOFAOMSOIntegrationPS.EslSfaOFAOMSOIntegrationPSHttpSoap11Endpoint" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="message" xmlns:task="http://www.wso2.org/products/wso2commons/tasks">

                <soapenv:Header/>
                <soapenv:Body>
                    <esl:operation/>
                </soapenv:Body>
            </soapenv:Envelope>
        </property>
    </task>

Answer 1

将 <property name="OUT_ONLY" value="true"/> 放入您的 EslSfaOFAOMSOIntegrationPS 代理中。

而且我认为您可以删除 to 属性，因为消息已发送到 proxyName 属性.
