19.2.2. Business Activities

A client creates and manages Business Activities using the UserBusinessActivityFactory and UserBusinessActivity classes. A WS-BA activity is started and associated with the client thread by calling the begin method of the UserBusinessActivity class. A client can terminate a business activity by calling the close method, and cancel it by calling the cancel method.
If any of the Web Services invoked by the client register for the BusinessActivityWithCoordinatorCompletion protocol, the client can call the completed method before calling the close method, to notify the services that it has finished making service invocations in the current activity.
More complex business activity management, such as suspension and resumption of business activities, is supported by the BusinessActivityManagerFactory and BusinessActivityManager classes.
Full details of the WS-AT APIs are provided in Chapter 21, The XTS API.
