The Development And Application Of The Group Annuity Customer Support System Based On J2EE

At the life insurance realm, the Electronic Commerce has already risen quietly, the important topic of the information-based construction is how provide the superior quality services for the customer. The Group Annuity Customer Support System did beneficial quest and the fulfillment in that realm. That system faces to VIP who insure the group annuity insurance, supporting unit operator query all branch organizations and personnel, supporting the unit operator carry on the account management, supporting the unit operator carry on various business application, supporting the human resource management, supporting annuity's try to calculate function, supporting personal on-line account query, exchange information with the core processing system real time.In the development process of the system, we not only carry through the principle request of the software system, but also combined a new technique to expand.1, Maturity and Expansibility. Choose J2EE technique is this project successful key. J2EE have already become the technique that sets up a widespread adoption of the Electronic Commerce platform, and have the cross-platform characteristic of "write once, circulate everywhere".2, Advancement and practicability. The development of the system, want to have a foothold to be in the farsighted development in the technique, system should at least can satisfy the business need of 3-5 years from now on. So we adopt structure mode according to the B/A/S of the J2EE, it divided into four layers. The first floor is the customer who circulates in the browser, its function lies in an interface design; the second floor mean a layer for the server, its function lies in accessing the business data that the customer carry, organizing the logic that the customer carry; the third layer is an applied server layer, its function lies in packing the applied business logic as a series of EJB; the fourth layer is the business enterprise information system layer, including an internal usage of insurance company of the core business system and various service of the Tuxedo server, they are the real entity of the business enterprises business logic.3, Dependability and stability. On the foundation of J2EE, we adopt WebLogic8.1 Be the WEB application server, Tuxedo8.1 Be trade in the Middleware, they are carry on contact through WTC. It improved the subsequent ability of the system, the safety of the system also got to promote biggest.4, Adopt MVC design mode. The Struts is the most classic Web application frame of the MVC mode, separate model, view, control design, Make forcibly the input, processing and output separate, make the business logicprocessing and page and data separate, weaken each part's relation. On the view layer, we still used the TagLib technic, simplifying to establish the process of the customer interface, a great deal of code of the JSP page can be economical, the whole applied procedure is easy to adjust to try with the maintenance, speeding a development progress and promising software quality in the meantime.5, Always use the Session Facade while using the EJB module. In the EJB design, the Session Facade applies the most extensive design mode. The Session Facade shielding customer to access the business object. The EJB customer access Session Bean to replace interview business object. When an EJB customer need to call the method of several business objects, it the remote method that need to be called on a wide degree, giving claim the Session Facade, then give claim the Session Facade, is again passed a native method by the Session Facade to adjust to use, adjust to use to correspond of business object, carry out its method. Eased the network load so, raise system function.The system starts design in 2004, using successfully in 2005. I am in that project not only undertook a need analysis, the system design, also undertook the detailed design and coding of some modules.
