Internet GIS based on JavaBean can be deployed into two tiers or N tiers application,which contains GIS browser,Web server,GIS application server and spatial database server.GIS browser is the Web browser which supports Java virtual machine,such as Netscape ,Ineternet Explorer.Web Server is the server which supports WWW,servlet and JSP,such as iPlanet Web server.GIS application servers is the servers which finish the critical business...

Internet GIS based on JavaBean can be deployed into two tiers or N tiers application,which contains GIS browser,Web server,GIS application server and spatial database server.GIS browser is the Web browser which supports Java virtual machine,such as Netscape ,Ineternet Explorer.Web Server is the server which supports WWW,servlet and JSP,such as iPlanet Web server.GIS application servers is the servers which finish the critical business logic,such as vector data service,image data service and DEM data service.Database server is the server which stores the spatial data.Spatial data organization on Internet is different from the traditional GIS.The goal is to access data simply and quickly.In general,it's geometry includes point,line,polygon and annotation. GeoSurfV4.0 is an example of Internet GIS software based on JavaBean.It contains four JavaBeans:GeoSurf2D,GeoSurf3D,GeoSurfTheme,GeoRouteServer.There are four different approaches to construct GIS application using component Internet GIS based on JavaBean:Java Application,Java Applet,Java Server Pages and Active Server Pages.

在分析WebGIS二次开发需求的基础上 ,提出了基于JavaBean的WebGIS组件概念 ,并详细阐述其特征、体系结构和空间数据组织 ;结合实例InternetGIS_GeoSurfV4 .0介绍了系统的设计与实现以及二次开发的方法与比较

With the increasing maturity of distributed object technology,CORBA,.NET and EJB are universally used in IT field. However, theory and practice of distributed GIS needs further improvement in virtue of contradictions between large scale vector data and limited network bandwidth or between transitory session and long transaction processing. Differences and trends among CORBA,.NET and EJB are discussed in details, the concept, architecture and characteristic of distributed GIS based on J2EE is provided afterwards, which contains GIS client application, Web server, GIS application server and spatial data server. Moreover the design and implementation of components of client application based on JavaBeans, the GIS engine based on Servlet, the GIS Application server based on GIS enterprise JavaBeans(contains session bean and entity bean) are explained. Lastly, the experiments of relation of vector data and response time under different conditions are conducted, which proves that distributed GIS based on J2EE can be used to manage, distribute and share large scale vector data.

分布式对象技术日臻成熟,流行的有CORBA、.NET和EJB3种解决方案,在IT领域已经广泛使用,在地理信息系统领域由于大数据量与带宽有限和短会话与长事务等诸多矛盾的存在,分布式地理信息系统的理论和实践还有待完善。在探讨CORBA、.NET和EJB3种分布式对象技术差别和发展趋势的基础上,重点阐述了基于J2EE的分布式GIS概念、原理和部件划分,并且阐述了基于J2EE的分布式GIS组件的设计与实现,最后通过矢量数据量与响应时间的关系实验证明这种体系结构下的解决方案管理、发布和共享海量空间数据是可行的。
