Abstract
Abstract An object oriented thread context manager, a method and computer program product are provided for object oriented thread context management. A context manager is provided for managing a plurality of ContextControl objects. Each ContextControl object comprises a plurality of methods for creating and suspending context on a thread for a target object. When a method request for a target object is received at a server process, the server process calls a thread manager requesting a thread. The thread manager calls the context manager for associating context with a current thread for the method request. Responsive to the context manager providing associated context with the current thread, the thread manager dispatches the method request for the target object. The thread manager calls the context manager for disassociating context with the current thread.
