public class JmsDestinationPollingSource
extends AbstractMessageSource<Object>

A source for receiving JMS Messages with a polling listener. This source is only recommended for very low message volume. Otherwise, the JmsMessageDrivenEndpoint that uses Spring's MessageListener container support is a better option.
