/**
 * This operation follows standard bean convention by matching property name to its corresponding 'setter' method.
 * Once the method was located it is invoked to set the corresponding property to a value provided by during service
 * configuration. For example, 'channel' property will correspond to 'setChannel(..) method and 'queueManager'
 * property will correspond to setQueueManager(..) method with a single argument.
 *
 * There are also few adjustments to accommodate well known brokers. For example ActiveMQ ConnectionFactory accepts
 * address of the Message Broker in a form of URL while IBMs in the form of host/port pair (more common). So this
 * method will use value retrieved from the 'BROKER_URI' static property 'as is' if ConnectionFactory implementation
 * is coming from ActiveMQ and for all others (for now) the 'BROKER_URI' value will be split on ':' and the
 * resulting pair will be used to execute setHostName(..) and setPort(..) methods on the provided ConnectionFactory.
 * This may need to be maintained and adjusted to accommodate other implementation of ConnectionFactory, but only
 * for URL/Host/Port issue. All other properties are set as dynamic properties where user essentially provides both
 * property name and value, The bean convention is also explained in user manual for this component with links
 * pointing to documentation of various ConnectionFactories.
