The method is a mean of creating a provider-specific destination instance, which is an object that incapsulates the name of the destination, instead of looking it up in JNDI. The returned object is similar to the instance retuned from JNDI. The documentation specifically advises against using this method, in favor of JNDI lookups. An active session is required. The method does not actually create the physical destination on the JMS provider, and if the destination is not available, the method throws a JMSException with a "There is no queue with name ..." message, or similar.
