An enterprise computing platform is a combination of emerging technologies and methodologies on which people can perform business activities to produce values. In recent years, several new technologies have boosted the evolution of the enterprise computing platform toward a more efficient and effective computing. However, only a few enterprises can utilise these technologies effectively and incorporate them into the platform. This research targets examining and creating a reference model and, more importantly, gives an answer as to how to instrument the integration adapter over an enterprise computing platform. This research starts from an enterprise application architecture survey. Based on results, the research team proposes a reference model for the platform. An integration framework, iCell is proposed to fulfil the integration gaps in the proposed architecture reference model. Finally the proposed artefacts are examined in a real enterprise application project to evaluate the impacts both on technology and on business.

In this research, we simplify Web Services Distributed Management (WSDM) interfaces developing effort. The interfaces are generated by program code that must be created during development. Developers do not have to understand all Web services standards. On the other hand, the management system should provide message flow oriented management atomically without modifying service code. Enter prise can control all flows and review them at any time. Enterprise can build a quickly, efficient and extensible management system in the Web services environment

With the growth of internet, the requirement for the communication and message exchanges between programs becomes more and more important. The Message-Oriented Middleware (MOM), such as Java Message Service (JMS), could not only greatly reduce the technical learning curve for programmers but also have some amazing characteristics: such as reliable, secured, and event-driven. In the traditional client-server architecture, not only the client side program has to maintain the resource for connections and memory management, but also the server side has to send out several copies of duplicated messages per amount of connected clients. It not only wastes the system resource but also the network bandwidth. A system this paper developed is Fast Java Messaging 2 (FJM2), it's a enhancement version from Fast Java Messaging (FJM). It creates a whole new JMS provider which is distributed, high performance, reliable, and easy to use and deploy. While compared with FJM, FJM2 adapts a more efficient communication protocol-Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM), and does not adapt topic addressing. Moreover, FJM2 has the ability to work across WAN environment to extend the system coverage, and could be adapted for more different application scopes. It would benefit those who want to create a MOM system based on Java and multicast protocol.
