A Framework for e-Service Management and Invocation in Application Integration Systems

Application integration is the key to building new business process based on
heterogeneous, distributed legacy applications or systems. As more and more
applications are exposed in the form of e-Services over a network, service-oriented
integration is developing on the horizon of the application integration frontier.
Therefore, the management and invocation of distributed and diverse-form e-Services
become a challenge for application integration system. In this paper, we introduce an
Action Invocation Framework to address this problem. By leveraging private UDDI,
this framework could facilitate service registration, categorization & relationship
management, uniform service invocation interface exposure. It also handles the
interface brokering and invocation for diverse forms of e-Services. The embedded
transaction support enables the service to be securely invoked and executed, or rolled
back when errors occur. In this paper, we introduce the initiatives of developing such a
framework, and then the architecture of the framework is presented. At the end of this
paper, a self-service banking application scenario is described, in which AIF facilitates
the e-Services aggregation and transaction requirement.
