Query on best practices for coding.

Hello ! 
I have the following code dilemma: 

-- The restricted & simplified question --
A participant in a DS must translate the incoming ISO8583 request to an external 3rd. party message format, just before sending it via QueryHost. This translation is rather straightforward.

Case a) Translation is done in ( or by ) the participant itself
Case b) Participant instantiates a translator class and calls this class's methods.
In case a) the participant itself does the translation job . This is rather the practical solution. If the same target format is needed in the future but with additional data, another participant may call super.xLate( theRequest ). 

In case b), the participant is just an orchestrator, and instantiates a translator class xLator = new ISO23rdParty() ; xLator.xLate( the Request ) . This is rather the academic solution.

Which, case a) or case b), is the solution that fits best practices in jpos domain ?

Now -- The general question --

To delegate all that is possible, or not to delegate at all ( or delegate the minimum ) ?

It depends on how complex the translation is and how reusable for similar implementations your code is.

I'd probably go with the latter, as a matter of fact, that's what we tend to do. Use a translator for most of the message, and perhaps tweak it a bit as part of the specific participant.
