About this course
The EJB development course will teach Java programmers how to use EJB to build better enterprise systems. Jakarta Enterprise Beans (EJB; formerly Enterprise JavaBeans) make it easier to build Java systems with reusable components. EJBs make your system more robust and better able to scale.This course will teach you how to write different kinds of EJBs: session beans to control the application business logic, entity beans to handle persistent business data, and message-driven beans to allow different systems to communicate with each other.
