Red Hat Certified Specialist in Enterprise Application Development Exam

EX183ExamApplication Services 1 day

The Red Hat® Certified Specialist in Enterprise Application Development exam (EX183) tests whether you have a basic understanding of the core enterprise Java APIs that are required to implement modern, stateless business services.

The exam focuses on using the default behavior of the minimal set of JEE APIs that are applicable across all modern Enterprise Java application development environments:

Using JAX-RS for simple REST create, read/search, update, and delete APIs.

Using JAAS to secure access to services.

Using stateless EJBs to provide business logic.

Using CDI to integrate components.

Using JMS to send and receive messages.

Using Bean Validation to ensure data format and consistency.

Using basic JPA to create, read, update, and delete persistent objects and their relationships.

By passing this exam, you become a Red Hat Certified Specialist in Enterprise Application Development. This certification counts toward becoming a Red Hat Certified Architect in Cloud-native Applications.

This exam is based on JBoss Enterprise Application Platform 7.

What you'll learn

Using Red Hat JBoss EAP, you should be able to accomplish the tasks below without assistance. The tasks have been grouped into categories to assist your preparation.

Annotate a POJO to enable and set up data validation.
Use the documentation to find useful standard validators.
JPA mapping
Annotate a POJO to map it to its persistent state representation in the database.
Apply basic property mapping and be able to use the documentation to identify correct property annotations (e.g., @Temporal).
Map a bidirectional OneToMany relationship between two entities, including both sides of the association.
Understand default fetching behavior and be able to override the fetching strategy per association.
