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.)
To integrate a Java EE application with a legacy system developed using non-Java technologies, JMS (Java Message Service) and JCA (Java Connector Architecture) are the appropriate technologies in the integration tier. JMS enables messaging between different systems, allowing communication regardless of language or platform. JCA is designed specifically for connecting Java EE applications with heterogeneous enterprise information systems, making it suitable for integration with legacy systems.
