Introduction

WebSphere Lombardi Edition V7.2 (hereafter called Lombardi Edition) has two kinds of message events: Intermediate Message Event (IME) and Start Message Event (SME). A message event represents a data where incoming message is captured. A message event is derived from several sources, one of which is from the Undercover Agent (UCA). When receiving the message event, you need to have a message event listener respond to the event. The IME listens to all events occurring anywhere in the process. The function of the SME is similar to the Start Event based on the incoming message.

Objectives

This tutorial demonstrates both Intermediate and Start Message Events. The events are released by the UCA. The IME (listener) restarts an activity, terminates a process, and updates a process state. The SME (listener) starts a new process application.

In this tutorial, you will learn how to use the:

  • UCA to generate message event.
  • Coach and embed JavaScript into your activity.
  • IME to end the process.
  • IME to restart an activity.
  • IME to update a process state.
  • SME to start a new process.
