One goal of a Computational Grid is to aggregate ensembles of shared, heterogeneous, and distributed resources to provide computational “power” [Foster00]. The increasing use of Web technology Internet and Intranet is making the Web an attractive framework for solving distributed applications, in particular, because the interface can be made platform independent. Several systems have been developed that make distributed computing available. However, these systems are either not web-based or not taking the enterprise Java technology [Chen97]. Typically, those systems are unnecessarily complicated and require long development.;This thesis is an approach to research and development on distributed, multi-server code service system model—SpiderNet. While a service-based architecture for distributed computer systems is not new, a theory and practice approach on using EJB in multi-server environment is presented in this thesis report. It adapts enterprise Java and web application server technology trying to solve the fundamental problem of multi-server model: work balance for efficiency and fail over for availability.;This thesis also demonstrates that with using Web and enterprise Java development toolkit, it is possible to build applications using a graphical “drag-and-drop” and web-based interface, thereby speeding up the application development.
