摘要： CCM和EJB代表了当前业界最主流的两种组件技术,将被越来越广泛地应用于分布式系统的开发和部署中。如何在这两种技术中进行选择是分布式系统开发面临的首要问题之一。该文对最新版本的CCM 3.0与EJB 2.1在组件类别、接口定义、编程语言、运行效率、支持的工具尤其是公共服务能力等方面作了深入而细致的比较和评价。最后作为总结,给出了实际应用中对这两种组件技术的选取原则。

Abstract: The CCM and EJB stand for the two leading component technologies, which will be more and more widely applied to the development and deployment of the distributed systems. It is one of the most important problems for the distributed systems to choose a suitable one between the two technologies. Full and deep comparison and evaluation between the latest version of CCM 3.0 and EJB 2.1 are given, which focus on the component categories, interface definitions, programming languages, run-time performance and supported tools, etc., especially on the common service capabilities. In conclusion, the principles of choosing the two component technologies are pointed out.
