Integrating enterprise application using message-oriented middleware and J2EE technologies

Enterprise systems integration allows applications to be connected to one another in intra- as well as inter-organizational settings. Despite providing tremendous benefits, enterprise-wise integration is complicated. Several integration technologies are available ranging from electronic data interchange, enterprise resource planning, enterprise application integration (EAI) and Web service. This study focuses on enterprise applications integration approach using message-oriented middleware (MOM) and Java 2 Enterprise Edition (J2EE) technologies. The middleware serves as a bridge between the different applications involved in system integration. Using a common interface layer rather than point-to-point integration enables all the involved applications to communicate freely with each other. Moreover, EAI approach allows the reuse of existing applications besides allowing new applications and data to be incorporated. A prototype of the proposed EAI architecture is implemented in a banking environment scenario.
