WebGIS developing architecture and working mechanism based on J2EE platform

By deep analysis of J2EE platform and WebGIS systematic structure, this section settles the key technology of the coordinated operation of J2EE and WebGIS, expatiates the cooperation principle, proposes a WebGIS developing architecture based on J2EE platform, and then gives the working mechanism of WebGIS directed by this architecture. The architecture avoids the illogicalities and problems which lying in the architecture of nowadays correlative research and application about WebGIS, offers a optimized architecture for WebGIS development, and has definite value in theory and application.
