WebSphere Process Server (hereafter called Process Server) supports a number of human task types, namely standalone, ad hoc, and inline. Each task type has a lifecycle that consists of states and transitions between states. Process Server manages these task states and enables you to provide the following plug-in types to customize the task-related logic:
- Task API event handler: This is executed by the Process Server task container at specific points before or after the task API call
- Task escalation notification event handler: This is executed by the Process Server task container when a task is escalated.
- People resolution plug-in: This is executed by the Process Server task container to customize the returned result set of task-related users, such as task potential owners.
The purpose of this tutorial is to provide a step-by-step procedure to develop, configure, and test a simple task API event handler and invoke a service from the task API event handler.
