📨

JMS Messaging

Point-to-point vs publish/subscribe, queues, topics, MessageListener, and message-driven beans.

🌐

REST Services with JAX-RS

HTTP methods (GET/POST/PUT/DELETE), @Path, @Produces, @Consumes, JSON and XML content types, standard HTTP return codes, and RESTful root resource classes.

@GET @Path("/{id}")
@Produces(APPLICATION_JSON)
public Customer find(
 @PathParam("id") Long id)

🔐

JAAS Security

JAAS concepts, secure REST and EJB services with @RolesAllowed, @DenyAll, and @PermitAll annotations.

Why EX183

The Enterprise Java Certification That Employers Trust

Java EE / Jakarta EE powers the banking, insurance, and enterprise software market. EX183 proves you can build real-world stateless services with the APIs these industries depend on.

Java EE Powers Enterprise Systems

Banking, insurance, government, and telecom applications run on Java EE / Jakarta EE. EX183 certifies you can build and maintain those systems.

Performance-Based, Employer-Trusted

EX183 is a live coding exam — you write working Java code against real APIs. Employers value it because it proves practical skill, not test-taking ability.

High-Salary Enterprise Dev Roles

Certified Java EE developers command premium salaries at banks, consultancies, and enterprise software vendors globally.

Complete API Coverage

Our 7-module curriculum covers Bean Validation, JPA, JAX-RS, JMS, JAAS, and CDI — the exact APIs tested in EX183.

Hands-On JBoss/WildFly Labs

Every module is built around practical coding exercises on real WildFly and JBoss EAP environments — not slides alone.
