Usage

From source file:org.springframework.jms.connection.ConnectionFactoryUtils.java

/**
 * Obtain a JMS Session that is synchronized with the current transaction, if any.
 * @param connectionFactory the JMS ConnectionFactory to bind for
 * (used as TransactionSynchronizationManager key)
 * @param resourceFactory the ResourceFactory to use for extracting or creating
 * JMS resources/*  www.  j av a2 s.  c  o  m*/
 * @param startConnection whether the underlying JMS Connection approach should be
 * started in order to allow for receiving messages. Note that a reused Connection
 * may already have been started before, even if this flag is {@code false}.
 * @return the transactional Session, or {@code null} if none found
 * @throws JMSException in case of JMS failure
