官方Java开发工程师QQ群(27163376),验证请输入您的ID。给刚刚毕业没有经验的人预备的,有了它基本书面考试可以搞定了1:EJB:答:?EnterpriseJavaBean相当于DCOM,即分布式组件。它是基于Java的远程方法调用(RMI)技术的,所以EJB可以被远程访问(跨进程、跨计算机)。但EJB有必要被布署在比如Webspere、WebLogic这样的容器中,EJB客户从不直接访问真实的EJB组件,而是通过其容器访问。EJB容器是EJB组件的代/l,EJB组件由容器所创建和管理。客户通过容器来访问真实的EJB组件。答:Enterprisejavabean容器。更具有行业领域特征。他提提供运行在其间的组件EJB各种管理功能。只需满意J2EE规范的EJB放入该容器,马上就会被容器进行高效率的管理。而且可以通过现成的接口来取得系统级别的服务。例如邮件服务、业务管理。......abbr_c15628d02cde04db130213bc9b07abb4.doc

With it, the basic written exam can be completed. 1:EJB: Answer:? EnterpriseJavaBean is equivalent to DCOM, that is, distributed components. It is based on Java's Remote Method Invocation (RMI) technology, so EJBs can be accessed remotely (cross-process, cross-computer). But EJB must be deployed in containers such as Webspere and WebLogic. EJB clients never access real EJB components directly, but through their containers. EJB container is the generation/l of EJB components, EJB components are created and managed by the container. Clients access real EJB components through the container. Answer: Enterprisejavabean container. more industry-specific. He provides various management functions of the component EJB running in between. As long as the EJB that meets the J2EE specification is put into the container, it will be managed efficiently by the container immediately. Moreover, system-level services can be obtained through ready-made interfaces. Such as mail service, business management. ......
