J2EE

J2EE - The Java 2 Platform, Enterprise Edition, defines the standard for developing multi-tier enterprise applications. The J2EE platform simplifies enterprise applications by basing them on standardized, modular components, by providing a complete set of services to those components, and by handling many details of application behaviour automatically, without complex programming.

The J2EE platform takes advantage of many features of the Java 2 Platform, Standard Edition ( J2SE), such as "Write Once, Run Anywhere" portability, JDBC API for database access, CORBA technology for interaction with existing enterprise resources, and a security model that protects data even in internet applications. Building on this base, the Java 2 Platform, Enterprise Edition adds full support for Enterprise JavaBeans components, Java Servlets API, Java Server Pages and XML technology. The J2EE standard includes complete specifications and compliance tests to ensure portability of applications across the wide range of existing enterprise systems capable of supporting the J2EE platform. In addition, the J2EE specification now ensures Web services interoperability through support for the WS-I Basic Profile.

Distributed Multi-tiered Applications

The J2EE platform uses a distributed multi-tiered application model for enterprise applications. Application logic is divided into components according to function, and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multi-tiered J2EE environment to which the application component belongs. Figure below shows two multi-tiered J2EE applications divided into the tiers described in the following list.

• Client-tier components run on the client machine.
• Web-tier components run on the J2EE server.
• Business-tier components run on the J2EE server.
• Enterprise information system (EIS)-tier software runs on the EIS server.

Making Middleware Easier

Today's enterprises gain competitive advantage by quickly developing and deploying custom applications that provide unique business services. Whether they're internal applications for employee productivity or Internet applications for specialized customer or vendor services, quick development and deployment are the key to success.

The J2EE specification supports emerging Web Services technologies through inclusion of the WS-I Basic Profile. WS-I Basic Profile compliance means that the developers can build applications on the J2EE platform as Web services that interoperate with Web services from non-J2EE compliant environments. J2EE platform is the platform for enterprise solutions with simplicity, portability, scalability, and legacy integration.
