2. Strengthen web development — Review servlets, JSF, JSP, Expression Language, and web application concepts.
3. Study CDI — Practice dependency injection, scopes, qualifiers, bean lifecycle, and contextual services.
4. Review EJB — Understand enterprise beans, component behavior, lifecycle, and transaction-related concepts.
5. Strengthen JPA — Review entities, relationships, persistence contexts, queries, and object-relational mapping.
6. Practice transaction management — Understand how transactions affect enterprise components and persistence operations.
7. Review REST services — Practice RESTful resources, HTTP methods, request handling, and responses.
8. Study supporting APIs — Review JSON processing, WebSocket, Bean Validation, messaging, and related Java EE technologies.
9. Review security — Strengthen authentication, authorization, and enterprise application security concepts.
10. Practice application scenarios — Analyze how different Java EE components behave and interact in real development situations.

Recommended Study Approach

A progressive study sequence can help organize your preparation:

• Begin with Java EE architecture and application components.
• Review servlet-based web applications.
• Study JSF, JSP, and Expression Language.
• Strengthen CDI and dependency injection.
• Review EJB concepts and component behavior.
• Practice JPA entities, relationships, and persistence.
• Review transaction management.
• Study RESTful web services and JSON processing.
• Review WebSocket, messaging, and validation.
• Strengthen Java EE security concepts.
• Practice mixed application-development scenarios.
• Revisit topics where your practice results show weaknesses.

How to Use the Practice Exam Effectively

Attempt each question independently: Solve the question before reviewing its explanation.

Analyze your mistakes: Identify the Java EE concept responsible for an incorrect answer.

Track weak technologies: Record recurring difficulties involving CDI, EJB, JPA, REST, servlets, transactions, or security.

Understand interactions: Focus on how Java EE components work together instead of memorizing isolated definitions.

Repeat targeted practice: After revising difficult topics, return to practice questions to confirm your understanding.
