Spring Mock Test 8

1. All errors thrown from Spring Integration components will be a subclass of:-

2. Spring Integration will use that header and forward errors encountered in the processing of this message to that channel.

3. You can configure a Quartz SimpleTrigger object in Spring bean configuration file through:-

4. To register an MBean, you need an instance of the interface :-

5. Sending all the errors to the same channel can eventually lead to a large switch-laden class that’s too complex to maintain.

6. MIME is supported by JavaMail through the:-

7. 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.

8. Spring-WS supports annotating an arbitrary class as a service endpoint by:-

9. For correlation when you might not have a size but know that you’re expecting messages that share a common header value within a known time, Spring Integration provides the HeaderAttributeCorrelationStrategy.

10. When you are using XML marshalling, WebServiceTemplate requires both the marshaller and unmarshaller properties to be set.
