14 Oct 2009 In Part 3 of this series, you'll learn how to implement a
mediation flow in WebSphere® Integration Developer V6.1.2, including
integrating a mediation flow with a business process.
Before you start
This series of four tutorials covers basic use of the complete IBM
WebSphere business process management (BPM) software suite for service
oriented architecture (SOA) environment from modeling a business
process through implementation and execution to monitoring. In this
series, we'll use a single example process to illustrate the BPM life
cycle and how it is supported by IBM products.
Prerequisites
- Intermediate knowledge of Eclipse technology.
- Intermediate understanding of application integration concepts
and technology, such as service component architecture (SCA),
service data objects (SDO), mediation flow, and more.
System requirements
- IBM WebSphere Integration Developer V6.1.2
Introduction
In Part 3, we'll continue to work with the IBM BPM V6.1.2 product
suite. Our use case is a human resource process of hiring a new
employee. In
Part
1,
we modeled the process in WebSphere Business Modeler. Next, we
implemented the process using WebSphere Integration Developer
(hereafter called Integration Developer). The process uses a service
to send e-mail to applicants, which we implemented as a dummy
Java™ service component in
Part 2.
In Part 3, we'll change the implementation to a mediation flow. Our
example company has access to two email service providers that have
different cost and quality of service attributes. Sending email is a
general service in the company and cannot be bound to any specific
business process, which is why it is implemented as a standalone
module.
As mentioned, there are two services to consume. The first service uses
a local, more secure SMTP server, and is used for the most important
partners, while the second uses Google™ mail as the SMTP
provider. The company has a database containing the list of important
partners. We'll use this database to choose the appropriate service.
In case of any failure of the remote service, the other service is
used as a backup.
