RE: [Quickfix-developers] NoRelatedSym Class

[Mike H. <mi...@an...>]

Hi Oren,

i have narrowed this down to being a java problem. I added a validation
test in C++ for the MarketDataRequest message and it passed OK. the XML
data structure (from toXML()) produced by C++ and java is identical.

Unfortunately there are no java bindings for the DataDictionary class -
so i couldn't repeat the test in java. i considered implementing
DataDictionary::validate via jni but thought something more basic must
be going on.

in java the data dictionary (FIX43.xml) appears to load OK and validate
other message types (e.g NewOrderSingle's) OK - my next step is to strip
the DataDictionary XML file down to only have the MarketDataRequest to
see if i get further.


Cheers
Mike
