Abstract
One of the challenges of Grid computing is the integration of legacy scientific applications. The Web Services Architecture (WSA) is an ideal technology to integrate legacy applications into the grid environment. Web Services Resource Framework (WSRF) extends Web Services and makes them stateful. Based on WSRF, we implement a framework which utilizes WSRF resource to submit applications and to monitor execution status. We deploy only one Factory Service to create the resources and one Grid Service as the uniform interface for all the applications in each computing resource. We can dynamically deploy some legacy applications in the Grid or remove these applications without stopping the execution of entire system. Moreover, we present an implementation of one meta-scheduler which integrates Grid resources in complex Grid environment.

Keywords  WSRF - Dynamic Deployment - Application Integration - Web services - Meta-Scheduler
