摘　　要：EJB(Enterprise Java Bean)是基于Java的,符合J2EE规范的服务器端组件架构技术,开发者能够利用其构建企业的、分布式的、多层次的组件应用软件,并且能够开发架构灵活、运行可靠及业务逻辑简单的应用系统,满足了平台独立、可移植、维护简便的要求。在SUN提供的应用服务器上,研究了客户对企业Bean(EJB)的远程调用,实现了应用程序、EJB本身或Servlet/JSP作为客户对企业Beans的远程驱动,并比较了不同客户对企业Beans远程调用的异同点,分析了使用编码名来调用EJB的优点。EJB is a component architecture technique on the server side, depending on Java and J2EE technique. Developers can easily build up distributed and multi-tier component application softwares for enterprises and sealable, reliable and simple application systems as well. This meets the requirements of platform independence, portability and simple maintenance. Various remote calls to EJB by clients like applications, Servlet/JSP and EJB itself are investigated and implemented on the Sun application system server. The similarity and difference of those remote calls are compared, and the advantage of using the JNDI coded name to invoke EJB is analyzed.
