Currently i am building a message queue program which
one is sending a message to another party.
lets say ABC sending a message to DEF
if ABC sends a msg out using message queue, it stores at the msg queue manager, once the msg stored in,i want the server side to detect the message and automatically alert DEF that he receives a msg. alert for example: pop up windows and etc...
i understand by using javascript : <server>
but how it works?
thank you
