[VC/MFC] commons-fileupload-1.3.3-bin.tar DL : 0: EJB是sun的JavaEE服务器端组件模型，设计目标与核心应用是部署分布式应用程序。简单来说就是把已经编写好的程序（即：类）打包放在服务器上执行。凭借java跨平台的优势，用EJB技术部署的分布式系统可以不限于特定的平台。EJB (Enterprise JavaBean)是J2EE(javaEE)的一部分，定义了一个用于开发基于组件的企业多重应用程序的标准。其特点包括网络服务支持和核心开发工具(SDK)。在J2EE里，Enterprise Java Beans(EJB)称为Java 企业Bean，是Java的核心代码，分别是会话Bean（Session Bean），实体Bean（Entity Bean）和消息驱动Bean（MessageDriven Bean）。在EJB3.0推出以后，实体Bean被单独分了出来，形成了新的规范JPA。(EJB is sun's JavaEE server-side component model. The design goal and core application is to deploy distributed applications. In short, the program that has been written (that is, class) is packaged and executed on the server. With the advantage of Java cross platform, the distributed system deployed with EJB technology can not be limited to a specific platform. EJB (Enterprise JavaBean) is part of J2EE (javaEE), and defines a standard for developing component-based enterprise multiple applications. Its features include network service support and core development tool (SDK). In J2EE, Enterprise Java Beans (EJB), called the Java enterprise Bean, is the core code of Java, which are session Bean (Session Bean), entity Bean and message driven ones. After EJB3.0 was launched, entity Bean was isolated and formed a new specification JPA.)
