This course focuses on Enterprise JavaBeans, as specified in the EJB 3.x specification as part of the latest version of Java EE.
Attention is paid to the different types of Enterprise Beans like Session Beans, Message Driven Beans and Singleton Beans.
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.
The important role that annotations play in Java 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.
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 Java EE environment is considered.
Attention is paid to the Java 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.
And finally the focus is on best practices and design patterns in EJB technology.
Java developers that want to learn how to develop of Java EE EJB business components.
To participate in this course knowledge and experience with Java programming is required. Knowledge of Java Web development is beneficial for a proper understanding.
The theory is explained using presentation slides and is interspersed with practical exercises. Demos are used to clarify the theory. All topics that are asked in the Java EE Enterprise JavaBeans Developer Certified Expert Exam (1Z0-895) are discussed. The course material is in English.
After successful completion of the course participants receive an official certificate Java EE EJB Business Components.
