What is the full form of EJB?
The EJB full form is Enterprise Java Bean. EJB is one of the Java API (application programming interfaces) for the Java Platform, Enterprise Edition (JEE) for enterprise applications that are designed to be flexible and manageable. Sun Microsystems can facilitate the growth and extension of big, fixed, guaranteed, and scalable application components.

EJB is a server-side and platform-independent software component that is inflexible, guaranteed, defined, multi-layered, and used by application programs to express the essential characteristics of business processes. It thereby promotes app developers by allowing them to focus on their business operations.
EJB types
EJB is divided into three categories.
Entity bean
EJB entails the preservation of the item. It is a portion of data that maintains the database’s information.
Session bean
Session beans are non-persistent objects. The customer’s business logic is implemented. It can calculate interest on deposits for a banking application, for instance.
Message-driven bean
It is implemented in an asynchronous communication system, such as the formulation of JMS messages since it organizes concurrently occurring messages.
EJB’s Requirement
- Data and services are dispersed over numerous places.
- When the software must be adaptable and efficiency is paramount.
- Whenever a user requires the coordination of transactions, the EJB web framework can coordinate transaction limits.
- A disjunction between business logic and presentation whenever the application requires the expression of business logic’s fundamental properties.
EJB uses
- In a Web-centric architecture, EJB will contain the business logic that resides beneath Web-oriented components such as servlets and JSPs.
- EJBs can be utilized by thick client applications, such as Swing applications, similar to Web-centric applications.
- EJBs may serve as a bridge between the network technologies commonly used to disseminate business-to-business (B2B) e-commerce and enterprise applications.
Benefits
- Access to EJB is protected at no cost.
- Within the EJB, declaratory payments are made.
- EJBs also use caching and pooling to boost speed. EJB web containers implement EJB life cycles.
- The EJB facilitates remote access and its scalability is rising.
- Programming is possible if attributes or annotations are utilized.
- There are numerous difficult choices accessible for free use.
