Then, based on the Struts framework, AJAX, EJB technology system detailed design and realization. The system design using J2EE level framework-four-level application structure with client, Web, EJB, database. The system uses Web services, greatly simplifying the system architecture, thereby improving system scalability and reusability. Utilizing AJAX to empower the dynamic effects on web pages, which makes the interface more user-friendly and provides a rich user experience. Web tier MVC design pattern using Struts framework, EJB tier SLSB and DAO design pattern. DAO operating logic of various databases.This system is a cross-platform, easy to maintain, scalable, high-performance, secure, open system, support in the business more than corporate settlement, multi-bank third party custody, support proxy settlement, and taking into account the changes in the coming period a variety of innovative business and settlement patterns.
