Hi,

I work for a trade routing system where our client feeds to two different systems. One of these systems is on FIX.5.0 and the other FIX.4.4. I was under the impression that both message types could be fed on the same session as follows:

TransportDataDictionary=FIXT11.xml
AppDataDictionary=FIX44.xml
AppDataDictionary.FIX.5.0=FIX50.xml
BeginString=FIXT.1.1
DefaultApplVerID=FIX.5.0

On messages going to system A(FIX5.0) we set ApplVerID=7.
On messages going to system B(FIX4.4) we set ApplVerID=6.

However, when we feed messages down to system B we get the followig:

java.lang.ClassCastException: quickfix.fix50.ExecutionReport cannot be cast to quickfix.fix44.Message

Does anyone know if there is a solution for this, perhaps I have missed some config?

Any advice would be greatly appreciated

Is the receiving FIX 4.4 system also using FIXT 1.1 as transport? Both sides need to use FIXT 1.1 and are then be able to exchange different message versions on the same session.

Hi,

Yeah, both sides are on FIXT1.1 and I am able to send messages down on the session on FIX.5.0. I have also found where the class is being incorrectly cast…

Anyway, as John hassaid - this isnt really a protocol issue, so i have posted on

If anyone has further commoents, please do post here.

Thank you for your comments! Will hopefully find a suitable solution in due course.

The class cast that you refer to is a characteristic of the particular FIX implementation you are using - ie QuickFIX.

It does not reflect any limitation of the FIX protocol itself.

You would be best advised to post your question on the QuickFIX website.
