使用ESB部署时，数据服务失败
Data Service fails when deployed with ESB

我有一个数据服务，只在DSS环境中部署时才能完美运行。 在具有dss和esb的环境中部署时的确切数据服务将使具有简单输入参数的操作失败。

关于什么是失败的任何指针将不胜感激。

数据服务有两个操作;

1. 简单获取没有输入参数的信息，GetLastRequest
2. 更复杂的get操作，其中传入单个datetime参数，GetNewRequests

在仅DSS环境中部署时，两个操作都可以使用TryIT按预期工作

在DSS / ESB环境中部署时，第一个操作按预期工作。 使用TryIt时，第二个操作失败

操作2：GetNewRequests
