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.
