Jakarta EE Overview

The course Jakarta EE Overview discusses the main points of the Jakarta EE standard as it is implemented in application servers like GlassFish, WebSphere and JBoss.

Jakarta EE Components

Attention is paid to the role of the various Jakarta EE Application Components as Java Servlets, Java Server Pages and Enterprise Java Beans. In this respect the JSF Framework for Java Web Applications is also discussed.

Jakarta EE Services

Key Jakarta EE services such as JNDI (Java Naming and Directory Interface) and JTA (Java Transaction API) are part of the subject matter.

Database Access

The various options for accessing databases are treated as well. Attention is paid both to the SQL-based Java Database Connectivity (JDBC) technology and to the new Persistence API for storing objects directly.

Web Services

Furthermore other Java technologies in the context of Jakarta EE, such as Web Services based on SOAP and REST are discussed as well.

Jakarta EE Application Servers

During the day several application servers and Enterprise Java Bean containers that rely on the Jakarta EE standard are addressed. If time permits, JMX, Java Management Extensions, as an optional module, is treated.
