Abstract:
A re-engineering framework of legacy system based on distributed environment of J2EE partition is given. Improved level-clustering algorithm to extract system components is used, so the code can be easily removed to build distributed systems. At the same time, this paper also gives some module connection rules and module-deployment strategies suitable for J2EE partition. And a re-engineering process of enterprise’s legacy system to distributional system based on J2EE partition using this technology has been successfully realized, thus confirms this frame strong, practice and common.
Key words:
legacy system,
framework,
level-clustering algorithm
摘要： 给出基于J2EE分布式环境的遗留系统再工程框架。应用改进的层次聚类算法提取系统组件，能够方便地将代码取出以构建分布式系统。给出适用于J2EE 分布式环境的组件接口启发式规则和模块部署策略。实现企业遗留系统到J2EE分布式系统的再设计过程，验证该框架的强壮性、实用性和通用性。
