Struts and Hibernate technology are used to build a MVC framework for disaster risk assessment of the lightning WEB system for the first time, which provides a friendly interface for man-machine dialogue. The integration of Struts and Hibernate based on the J2EE framework achieves genuine loose coupling among layers of applications, improves the developing efficiency greatly and its maintainability and extensibility. By means of the integration of Struts and Hibernate, the system can be used to assess risks of buildings, service facilities and manage the parameters of assessment, records of assessment, thunderstorm data and the lightning data and so on. It is much more practical than that given by IEC.
