基于Proxy Factory的WSRF服务调度与监控

以WS—Resource工厂模式和EPR的可传递性为基础，提出一种Web服务资源框架（WSRF）服务调度和资源监控的机制。通过建立Proxy Factory服务，在代替客户端创建资源实例，并在进行端点引用传递的过程中成功实现WSRF服务的按需调度和对资源属性的监控。该机制具有调度时机更为合理、调度机制对服务方和客户端透明、资源监控机制不影响客户端操作和接口开放便于系统集成等优点，使得原有基于GT4开发的各种WSRF服务和客户端几乎不需改动就能在该机制下运行。

WSRF Services Dispatching and Monitoring Based on Proxy Factory

This paper presents a dispatching and resources monitoring mechanism for Web Services Resource Framework(WSRF) services based on WS-Resource factory pattern and Endpoint Reference(EPR) passing method.A Proxy Factory service is involved and substituted to create WS-Resource instance for client.In this process and the EPR passing process,on-demand dispatching and resource properties monitoring handlers are successfully inserted.It makes this mechanism more reasonable and transparent to clients or service prov...
