基于J2EE的分布式WebGIS架构及实现方法

Architecture of Distributed WebGIS Based on J2EE and Its Implementation

计算机网络和分布式计算技术的发展促进了WebGIS向分布式、组件化方向发展。J2EE服务器为多层Web应用系统提供了EJB容器和Web容器,利用J2EE开发WebGIS应用解决了传统WebGIS面临的一些矛盾。文中研究了基于J2EE的WebGIS总体设计架构,针对具体的应用项目给出了相应的实现方案,较好地满足企业级WebGIS应用的需要。

With the development of network and distributed computing technology, WebGIS is developing in the direction of distribution and component. J2EE server provides EJB container and Web container for Web applications. The technology of using J2EE to develop WebGIS applications can effectively solve some contradiction that exists in traditional WebGIS. This paper studies general design architecture of WebGIS based on J2EE. Meanwhile, it gives corresponding solution according to factual applications. Therefore, it meets the requirements of WebGIS applications in enterprise level for better.
