+ Exposing messaging system via POJO Gateway is obviously a great benefit, but it does come at the price so there
+ are certain things you must be aware of.
+
+ We want our Java method to return as quick as possible and not hang for infinite amount of time until they can
+ return (void , exception or return value). When regular methods are used as a proxies in front of the Messaging
+ system we have to take into account the asynchronous nature of the Messaging Systems. This means that there might
+ be a chance that a Message hat was initiated by a Gateway could be dropped by a Filter, thus never reaching a
+ component that is responsible to produce a reply. Some Service Activator method might result in the Exception,
+ thus resulting in no-reply (as we don't generate Null messages).So as you can see there are multiple scenarios
+ where reply message might not be coming which is perfectly natural in messaging systems. However think about the
+ implication on the gateway method. The Gateway's method input arguments were incorporated into a Message and
+ sent downstream. The reply Message would be converted to a return value of the Gateway's method. So you can see
+ how ugly it could get if you can not guarantee that for each Gateway call there will alway be a reply Message.
+ Basically your Gateway method will never return and will hang infinitely. (work in progress!!!!)
+One of the ways of handling this situation is via AsyncGateway (explained later in this section). Another way of handling it is to explicitly set the reply-timeout attribute. This way gateway will not hang for more then the time that was specified by the reply-timout and will return 'null'.
