Research And Implement Of Component Crossed Platform Based On XPCOM

In the past several years, the component technology unceasingly developed along with the software development scale expansion and the network development. At present, the component with opened the distributional system model theory already widely used in real world. Several kinds of primary technologies: CORBA,MSCOM,JavaBean, although all has each one superiority but also to have the insufficiency .So XPCOM appearances ,Cross Platform Component Object Module.This article unifies the Wu River stave hydroelectric power station- reservoir group optimization dispatch system ,the author introduced the XPCOM.Based on Web Service, integrated two parts, established an more open efficiency distributional Web computation componen . During unifies XPCOM and the Web service, the author finded discovers one kind of more highly effective solution Java2XPCOM.The article first reviews the history of the development of computation pattern including the distributional module technology and the multilayered system structure. And discusses the develop- ment present situation of the distributional structure ,and present situation of multilayer system structure development condition; then article analyses about XPCOM technology reservoir dispatcher system design, including project background ,project feasibility analysis as well as partial contents of overall system design ; finally the author has carried out partial modules of reservoir dispatcher system based on the XPCOM technology and the analysis of the performance.
