Q. In EJB 3.0, an MDB can be a POJO that implements the MessageListener interface and is annotated with the:-

View solution

Q. You create a message listener to listen for JMS messages. This negates the need for the approach taken in BackOfficeImpl in previous recipes.

View solution

Q. A message listener must implement the:-

View solution

Q. When a JMS message arrives, the onMessage() method will be called with the message as the method argument.

View solution

Q. Method to convert MapMessage Object into Spring runtime exception JmsException.

View solution

Q. Spring provides several types of message listener containers:-

View solution

Q. If you have a transaction requirement in receiving messages, you have to use:-

View solution

Q. You have to set the delegate property of MessageListenerAdapter to your target bean.

View solution

Q. Using Spring JMS support with a very simple instance of:-

View solution

Q. ActiveMQ, provides only one pooled connection factory class alternative.

View solution

Q. It caches consumers correctly, or use Spring ConnectionFactory implementations.

View solution

Q. Implementation which returns the same underlying JMS connection each time (which is thread-safe according to the JMS API) and ignores calls to the close() method.

View solution

Q. Integration of Spring which has each application produce files of shared data for others to consume.

View solution

Q. Integration of Spring which has the applications store the data they want to share in a common database.

View solution

Q. Integration of Spring which has each application expose some of its procedures so that they can be invoked remotely and have applications invoke them to initiate behavior and exchange data.

View solution

Q. Integration of Spring which has each application connect to a common messaging system and exchange data and invoke behavior using messages.

View solution

Q. Using an ESB lets you hide the origin of the message from the code that’s handling it.

View solution

Q. As with a standard MDP, a configuration for the ConnectionFactory exists.

View solution

Q. The configuration starts with the inboundHelloJMSMessageChannel channel, which tells Spring Integration what to name the point-to-point connection from the message queue to the:-

View solution

Q. An adapter is a component that knows how to speak to a specific type of subsystem and translate messages on that subsystem into something that can be used in the Spring Integration bus only.
