An Extensible Management Model and its Implementation for Web Application Servers
Web应用服务器的可扩展管理模型及其实现

Web application server is a distributed system that provides runtime services for transactional Web applications. It must be capable of managing many types of resources. Also it needs to integrate the former mature network management protocols and systems. So how to manage Web resources,applications and services becomes a difficulty of implementing a Web application. To solve the problems ,this paper presents a JMX (Java?Management Extensions) based extensible management model with the advantage of flexibility, openness and extensibility. Then the key technologies on how to implement the model, including the implementation of the extensible management kernel , the remote management of resource and the extensible management of service are described. We have implemented the model in WebFrame2- 0 application server which is a J2EE application server.
