在此URL上：http://my.domain.com:9763/services/Test_DataService.SOAP12Endpoint，我收到以下消息：

This XML file does not appear to have any style information associated with it. The document tree is shown below.
    <soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
        <soapenv:Text xml:lang="en-US">
        The endpoint reference (EPR) for the Operation not found is          /services/User_DataService.SOAP12Endpoint and the WSA Action = null. If this EPR was    previously reachable, please contact the server administrator.
        </soapenv:Text>
    </soapenv:Reason>

PS：我在Amazon上使用Oracle RDS测试了WSO 2 DSS 2. 7和3本地和远程（所有情况下都出现相同的错误）。
有人能帮帮我吗？
非常感谢！
