Java EE 7 Application Developer — Question 30

A Java EE application that uses an EJB container must communicate with a legacy system developed using non-Java technologies.
Which two Java EE technologies can be used in the integration tier of the application? (Choose two.)

Answer options

• A. JMS
• B. JSF
• C. JPA
• D. JCA

Correct answer: A, B

Explanation

JMS (Java Message Service) is suitable for communicating with legacy systems through messaging, while JCA (Java Connector Architecture) allows for integration with various non-Java systems. JSF (JavaServer Faces) is primarily for building user interfaces, and JPA (Java Persistence API) is focused on data persistence, making them less relevant for integration purposes.
