EJB Architecture

• Component-Based:

  • Modular Design: Encapsulates business logic into reusable, server-side components (EJBs).

• Transactional Support:

  • Declarative Transactions: Automatically manages transactions, ensuring data integrity and consistency without explicit coding.

• Security:

  • Built-in Security: Provides authentication and authorization to secure access to EJBs and data.

• Scalability:

  • Horizontal Scaling: Supports deployment across multiple servers to handle increased load and user traffic.

• Concurrency Management:

  • Thread Safety: Manages concurrent access to beans, ensuring safe execution of business methods.

Before learning EJB Architecture, you should have the following skills:

1. Java Programming: Proficiency in Java, including core concepts and object-oriented programming.
2. Basic Understanding of J2EE: Familiarity with Java EE technologies like Servlets, JSP, and JDBC.
3. Database Knowledge: Understanding of relational databases and SQL for working with data persistence.
4. Networking Fundamentals: Knowledge of network protocols and concepts for understanding distributed applications.
5. Basic Security Concepts: Awareness of security principles relevant to enterprise applications.

By learning EJB Architecture, you gain the following skills:

1. Enterprise JavaBeans Development: Expertise in creating and managing session beans, entity beans, and message-driven beans.
2. Transactional Management: Proficiency in handling transactions using declarative and programmatic approaches.
3. Security Implementation: Knowledge of implementing authentication and authorization mechanisms in enterprise applications.
4. Scalability and Performance: Skills in designing scalable applications that can handle high transaction volumes and load balancing.
5. Concurrency Control: Ability to manage concurrent access to EJBs and ensure thread safety.
