Jakarta EE EJB Business Components

Enterprise Bean Types

Attention is paid to the different types of Enterprise Beans like Session Beans, Message Driven Beans and Singleton Beans.

JNDI

The Java Naming and Directory Interface (JNDI) is discussed and the simplification of how beans can be located and instantiated through injection. Attention is also payed to the lifecycle of the different types of beans and to concurrency issues.

Annotations

The important role that annotations play in Jakarta EE and EJB's is discussed as well. Annotations do their work in many places such as in establishing links with resources and the realization of persistence.

EJB Query Language

Also the use of the EJB Query Language and the implementation of Object Relational Mapping in EJB 3.x is part of the course schedule. Also the use of transactions in a Jakarta EE environment is considered.

Security

Attention is paid to the Jakarta EE security architecture and the various authentication and authorization strategies. JMS and its use in combination with Message Driven Beans is also on the course program.

Best Practices

And finally the focus is on best practices and design patterns in EJB technology.
