Macos ESB 4.0.3中的WSO2数据服务（DS）返回错误的故障消息

我在苹果公司工作，我们正在开发使用WSO2 ESB和数据服务功能的原型。我正在使用带有DSS特性的WSO2 ESB 4.0.3。我已经在ESB中部署了数据服务并从代理服务调用了数据服务。我正在使用MacOSX10.7.4和java版本，详细信息如下

java版本“1.6.0_31” Java（TM）SE运行时环境（构建1.6.0_31-b04-415-11M3635） Java HotSpot（TM）64位服务器虚拟机（构建20.6-b01-415，混合模式）

我的DS服务需要某个参数，比如参数A，我没有在输入XML中传递该参数，我在WSO2 ESB控制台上看到以下错误

查看SOAP错误时，我必须将错误消息返回给客户端，但我甚至认为正确的错误消息必须是“参数丢失”SOAP错误的原因文本是“

javax.xml.stream.XMLStreamException

”

---

我做的有什么不对吗？还是DSS中有BUG？

通过查看stacktrace，我可以看到您在调用服务时启用了SOAP跟踪程序，禁用了SOAP跟踪程序，您应该会得到正确的错误消息

干杯，

正如错误消息本身所解释的，它需要输入参数，而请求中没有输入参数。它可以通过两种方式固定：

不带值地从ESB传递空标记

在DSS中设置默认值

第一个选项适用于所有版本，下面是设置默认值的示例

<payloadFactory media-type="xml">
    <format>
        <ds:DATA_SERVICE_REQUST xmlns:ds="http://ws.wso2.org/dataservice">
            <ds:INPUT_PARAM_1>$1</ds:INPUT_PARAM_1>
        </ds:DATA_SERVICE_REQUST>
    </format>
    <args>
        <arg xmlns:ds="http://ws.wso2.org/dataservice" evaluator="xml" expression="get-property('INPUT_PARAMETER')"/>
    </args>
</payloadFactory>
<call>
    <endpoint>
        <address uri="DSS_END_POINT"/>
   </endpoint>
</call>

如果这个问题仍然没有解决，那么如果您能够提供API的详细信息就好了

<query id="QUERY-ID" useConfig="DATA-SOURCE-ID">
    <sql>-------------SQL QUERY HERE -----</sql>
    <result ----------- >
        <element ------------ />  
    </result>
    <param defaultValue="#{NULL}" name="PARAM-NAME" ordinal="1" sqlType="INTEGER"/>
</query>
