About this tutorial
Many long-running processes with human tasks must execute one or more service for each human task. One way to do this is to model the service invocation activities in parallel with human task activities in a process model. However, this approach has two drawbacks:
- The process model can easily become cluttered.
- It only implements one business requirement scenario where service invocation occurs in parallel with a human task creation.
WebSphere Process Server provides the task API event handler mechanism that enables you to execute any kind of logic, including a service invocation at the various task states (not just when the task is created). This tutorial demonstrates this capability of WebSphere Process Server.
You will learn to create a task API event handler and to invoke certain services from the handler.
You need to be familiar with WebSphere Integration Developer V220.127.116.11.
You need a machine with at least 2 GB of physical memory.
