A component architecture for the development and deployment of object-oriented, distributed, enterprise-level applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and secure.
Enterprise JavaBeans is a cross-platform component architecture for the development and deployment of multi-tier, distributed, scalable, object-oriented Java applications. Enterprise JavaBeans makes it easy to write business applications as components by providing a set of automatic services to support scalable transactional application server components. Enterprise JavaBeans can be deployed on top of existing transaction processing systems including traditional transaction processing monitors, web servers, database servers, application servers, etc. A standard JavaBean is, by definition, a client-side component that cannot, by default, be accessed and manipulated by other clients at runtime. Enterprise JavaBeans, in contrast, have no user interface component and reside entirely on an EJB-aware server such as CICS Transaction Server.
EJB(tm) reduces the complexity of developing middleware by providing automatic support for middleware services such as transactions, security, database connectivity and so on. It simplifies the middleware development that are transactional, portable and scalable.
A component architecture defined by Sun Microsystems for the development and deployment of object-oriented, distributed, enterprise-level applications (J2EE).
A specification of Sun Microsystems, Incorporated, that is part of the WebSphere Application Server Advanced Edition. EJB support allows your application to include sophisticated business components that run on your server. These components may include business logic with automatic distributed transactions and persistence to a relational database.
Enterprise JavaBeans (EJBs) is the Java technology supporting a distributed object paradigm. An EJB represents a business object that enables one to focus on the business rules of the application without worrying about protocols, transactions, database access, security, etc. This ease of use is accomplished by housing the EJB in an Enterprise Java Server (EJS) that handles all the non-application details and can be thought of as an object-oriented transaction monitor. These details are hidden from the programmer, who uses the EJB through a proxy that only exposes the methods relevant to the business logic. The proxy is created automatically. The EJS manages the lifecycle of the EJB, provides it with a security and transaction context, optionally manages bean persistence, and provides runtime performance enhancements such as pooling threads, database connections, and object instances. EJB
Enterprise JavaBeans are server component architecture that conform to the Sun EJB component model. The EJB may be used to create a business object and related content may be sent using Java server pages (JSPs).
A server-side component model for Java.
Java standard for creating reusable server components for building applications. They facilitate writing code that accesses data in a database.
