Jakarta Enterprise is the platform used to build modern distributed and scalable systems.
Central components of this platform are the new unified Java Persistence API (JPA) framework and the Enterprise JavaBeans component architecture (EJB).
This course is based on Jakarta Enterprise 8 and the EJB 3.1 specification and introduces the concepts of the persistence layer and Enterprise JavaBeans.
Through various exercises, participants gradually become familiar with the terminology and technologies of this important server-side architecture.
Course objectives
After this course, participants can develop simple applications based on Enterprise JavaBeans and JPA and evaluate the associated architectures.

Target audience / prerequisites
The course is aimed at software developers with object-oriented and Java knowledge equivalent to our “Java programming part 3 – building skills” or “Object-oriented programming with Java – intensive course”.
Attending the complementary “Jakarta Enterprise – web applications” seminar is helpful but not required.
Tools and materials
IDEs such as IntelliJ or Eclipse with JBoss Tools are used as development environments. Concepts covered in theory are reinforced through numerous practical computer exercises. All materials and exercises are in German.
WildFly is used as the runtime environment during development and testing. Hibernate is initially used as a standalone persistence framework.
