Chapter 12. J2EE Connector

Architecture scenario

This chapter gives an overview of the J2EE Connector Architecture (JCA) and

discuss its place in an SOA environment. The ITSOMart sample application has

been extended to access a back-end CRM system using a resource adapter. A

Web service that wraps the functionality accessing the CRM is used to access

the CRM through the ESB.

This chapter discusses how the design guidelines outlined in Chapter 7,

“Application and system design guidelines” on page 139 were applied to the

sample scenario. It also describes the process used to develop the sample

application as a way of illustrating development guidelines for JCA applications.

The sample has been deployed on WebSphere Application Server V6 and we

use the sample to illustrate runtime configuration tasks that must be performed.

Lastly, we discuss system management considerations for JCA applications.
