For some reason, a constructor method with the appropriate signature coul=
d not found in=20
the quickfix_jni.dll. I am not a windows expert at all, but I suggest to =
look at the=20
symbols exported by quickfix_jni.dll. Maybe also some dependent library, =
ie the XML=20
library is missing:

	Dictionary constructor is called
         shared loader loads objects needed by the constructor method...
         ...ie method/object from quickfix.dll
         ...shared loader loads objects needed for method/object from qui=
ckfix.dll
         ......libxml2 stuff not found

Just some thoughts...

Did you try the non-java unit tests? Do they run completely?

Anyway, all tests should run successfully, otherwise your QuickFIX instal=
lation will not=20
be usable.
