The Java based options are relatively slow as they offer maximum flexibility
as regards data types. 

Before venturing in COM/ActiveX and Java based solutions for the io pkg 4
years ago I've looked at a few other solutions, similar to yours. IIRC the
most promising one was posted in an OpenWatcom news group. All of them (i.e.
the "free solutions") suffered from the same limitations: lack of
flexibility, lack of documentation, dependency on some very specific
development framework, and/or bound to specific .xls formats (BIFF5, BIFF8,
OOXML, what not).

If you want I can look if your code can somehow be absorbed in the io pkg as
a sort of fall-back option.To that end it needs a suitable license and
someone should support/maintain it (my C/C++ skills are rudimentary).
