Simply speaking there are two diff systems which understand diff format.
one system say XXX will send a message throg MQ in a line by line format .. now these line will have say diff keywords which will indicate the nature of the order and what is to be done on that order.
and this will be parsed and understood and then converted into another format SAY to put it to YYY now this format is a string based format ( one full string ) of a specified bytelength .
this is a two way kind where message has to be processed from XXX - understood - parsed - conv to YYY format and viceversa. then againg place it in MQ

there is no GUI involved only trf of message thro MQ from one system to another

I think Mark Grand has a filter pattern in his Java Patterns I book.
What's trf? transformation?
