As job requirement, people more and more strict with software: stronger function, more simple operation, more short development cycle, less cost, more short testing time, higher software quality. In this condition, the requirement of people can't be satisfied by the tradition software development and the method of software development must be improved immediately. To solve this problem, researchers from several areas, such as software, system, multimedia, database, are spending much of theirs efforts on the related problems. However, the results obtained are not satisfied by either the researcher themselves or the public users.In this thesis, we used distributed technology into software development and made the method of software development adept to network technology. By contrasting with three mostly distributed object nowadays, OLE/COM/DCOM, CORBA and Java EJB, we selected EJB as the standard of developing distributed software bus.Based on the theoretical and experimental I aimed at the extension of EJB, and put forward the extension method based on XML, and have a test for the this method, and used this method on GIS. At the end of this paper, I design a EJB in Java, to implements the function of shortest path query, and use XML as it's query result. Simultaneity I optimize the Dijkstra arithmetic in test code. The test EJB deployed on BEA's Weblogic web server.
