[Quickfixj-users] Dynamic (vs. compile-time) message handling

[Naresh B. <NB...@sa...>]

I need some advice from this group about dynamic (vs. compile-time) =
message handling. I am in a situation where we are building a system =
that will talk to approximately 300 brokers. The brokers support varying =
levels of FIX and many of them have defined custom fields and groups. =
Supporting all these variations in code with type-safe APIs is going to =
be a nightmare, so I am willing to sacrifice compile-time safety in =
favor of dynamic message handling. I have started externalizing all =
message configuration in data dictionaries - one per broker (of course, =
these are based on one of 5 FIX4x.xml files provided with quickfix). =
Does this approach make sense?

So far I am doing pretty ok with message creation as well as parsing =
using the data dictionary, except with repeating groups. My hope was =
that I could create a Group definition right from the data dictionary, =
but the best it can do right now is to give me GroupInfo, thus loosing =
the field order. Am I missing something?

I also checked out the MessageFactory api, but as I understand it, it =
returns one of the generated Message or Group classes and does not use =
the data dictionary. Please correct me if I am wrong.

Thanks for your help.
