摘要
在阐述了WebGIS原理的基础上,将JavaApplet、Servlets、EJB与OracleSpatial结合,提出了基于J2EE框架的WebGIS系统实现方案。该方案实现了一个安全、跨平台的WebGIS原型,较好地解决了海量数据存储及多用户并发访问时客户机和服务器的负载平衡问题。
The paper expounds the theory of Web GIS,and presents the scheme of Web GIS imple-mentation based on J2EE framework by combining Java Applet,Servlets,EJB with Oracle Spatial.It gives a secure and cross-platform prototype of Web GIS to resolve the store of huge data and the load balance between the client compute r and server in the state of concurrent access.
