This paper describes how to use JSP+JavaBean model to develop the meteorological evaluation and management system,and analyzes some key techniques in the system implementation.we establish a model of quality evaluation in the implementation process of the project and list some examples though retrospective research.The system security,maintainability,reusability and scalability can be enhanced considerably by using this model,due to the interfaceandbusiness logic disjunction and threetier design of the structure,and the business logic encapsulated in the JavaBean.
