| In the process of developing commercial system, much work is repetitive, which leads to the waste of resources and high cost of maintenance and update. Web service and service composition provide a good solution. After analyzing the main characteristic of Web service and direction of service composition, this paper designs a web service composition-based resource management-ZYMS on the basis of service composition framework DartFlow. The mainly job of this paper is on following aspects:(1)Design the architecture of ZYMS system which bases on service composition framework DartFlow. In this foundation, we carried on the detailed design to the system from the function spot, the data flow as well as the essential technical angle. With comparison on current commercial resource management systems, summarized the ZYMS system three major characteristics: the low cost of maintenance and update, flexible definition of serviceflow, incompact coupling.(2)We divide the system into three children modules: client-module, configuration-module, and server-module. These modules are independent and concurrent. In the process of designing, we use the former system for reference.(3)First, we analyze the serial activity and hierarchical structure of web service in JTang server. Then, it gave all key process detailed description. At last, take the case of kernel web service; we give a description of the server-module with WSDL.(4)Introduce the service composition framework-DartFlow and application server-JTang. DartFlow consists of three parts: service registering module, serviceflow modeling module and serviceflow executing module. DartFlow provides several graphic tools for user to define a serviceflow and compose web services. JTang provides seven functions. Moreover, this application server will provide interfaces that access CORBA and DotNet technologies, as well as the integration with Tomcat server. |
