A Correct answer
Explanation

JMS (Java Message Service) requires a listener to receive and process messages from a queue or topic. The listener continuously monitors the messaging destination and invokes service processing when messages arrive. EJB uses direct RMI/IIOP calls, SOAP and HTTP use request/response patterns - none require continuous listeners like JMS.
