我发现我必须有另一个 GE，物联网配置管理器与物联网代理并行工作，以便管理我们将从中获取数据的实体。现在，XMLValidator 代码似乎给我带来了一些麻烦。我通过 HTTP POST osgi9 直接向配置管理器注册了一个实体。然后我尝试通过 osgi10 与 IoT 代理通信来访问它。IoT Broker 与 IoT DIScovery 服务通信并获得响应，但随后 XMLValidator 说 XML 是错误的，即使它显然不是。
这是 IoT 代理向 IoT ConfMan 请求资源的可用性：
2014-11-27 10:31:13,682 | INFO | (HttpConnectionClient.java:initializeConnection:170) | Output
Stream: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<discoverContextAvailabilityRequest>
<entityIdList>
<entityId isPattern="false">

</entityIdList>
<attributeList/>
<restriction>
<scope>
<operationScope>

</scope>
</restriction>
</discoverContextAvailabilityRequest>
然后 IoT Broker 获得：

收到的 xml 清楚地看到，至少收到了providingApplication，但 XMLValidator 没有看到这一点。
