RIA Integrated Framework And Its Application In The Marine Navigational Integrated Platform

With the development of Web2.0and multimedia technology, data form is becoming more and more diversified. Applications put forward higher requirements for data processing ability, while traditional HTML-based presentation layer technology is unable to achieve rich media processing requirements. The greatest advantage of Ajax technology is to be able to provide asynchronous interaction function between browser and server, which can obviously reduce the burden of server,and at the same time optimize the user experience.This thesis mainly study J2EE platform、the lightweight framework WSH (Webwork+Spring+Hibernate)、Ajax technology and DWR framework. According to their own characteristics, based on Ajax framework and J2EE, the RIA integrated framework is proposed, which can solve traditional Web applications’ problems, such as poor user experience, and improve the reusability and extensibility of the system.In the design, integrate J2EE platform and Ajax technologies. J2EE has obvious advantages in terms of reliability、scalability、load balance,etc, J2EE can improve the performance of the system, and reduce the difficulty and workload while developing. Taking advantage of Ajax on the client performance improvement, can effectively improve the user experience while surfing, and balance the pressure between client and server, thus improve the overall system performance.In the implementation, this thesis puts forward a new development mode:integrate the DWR and WSH, and applied the integrated framework into the actual development of Yunnan shipping and maritime service platform. By realizing direct remoting function in process monitoring module and message push function in office assistant, further demonstrates the feasibility and operability of RIA integration framework.In conclusion, the integrated framework can effectively reduce the coupling degree between layers, and make web application level clear. Mean while, the use of Ajax technology and its frame, have solved many common problem in most traditional Web application, and improved the browsing experience.
