所以我想请求LYo 2.1的RTC 3.X工作项目，但是我不能从流中提取它们：
客户端是OslcOAuthClient。
ClientResponse响应= client.getResource（resultsUrl，CT_RDF）;
ChangeRequest req = response.getEntity（ChangeRequest.class）;
我想知道正确的资源对象是ChangeRequest还是另一个？我的流中有（当我使用String.class时）：

最佳答案
RTC3是支持OSLC2的RTC的第一个版本，因此它同时支持OSLC1和OSLC2。默认情况下，RTC3返回OSLC1中指定的结果。因此，您的问题可能是OSLC4J期望得到OSLC2结果，但得到OSLC1结果。
发送请求时，应将OSLC-Core-Version标头设置为2.0。这将导致RTC3响应与OSLC2规范兼容的结果。
