摘要： 针对现有J2EE应用服务器在容忍入侵方面的不足，提出一种具有容忍入侵功能特性的J2EE应用服务器的构建方法。通过在J2EE应用服务器组通信层构建安全的群组通信系统和在服务器内部设计容忍入侵拦截器、容忍入侵框架，实现了容忍入侵服务的透明加入及集成、插拔和扩展功能。该设计方案运用容忍入侵、群组通信及拦截器技术为解决分布式环境下J2EE应用服务器领域容忍入侵问题提供了一个简便有效的方法。

Abstract: Aiming at the current J2EE application server’s limitation for intrusion tolerance, a method to design a J2EE application server with intrusion tolerance function is proposed. By the way of establishing a secure group communication system in the group communication layer of the J2EE application server, an intrusion tolerance interceptor and framework in the server are designed. The intrusion tolerance services can be added transparently and they are integratable, pluggable, expandable. The method applies intrusion tolerance, group communication and interceptor technology to provide a simple and available method to solve the intrusion tolerance problem of J2EE application server realm in the distributed environment.

Key words: J2EE application server, intrusion tolerance, interceptor, group communication, cluster
