Hi,

I have one question re. your Java function - do you want to use it just
for some test or do you want to use it in production?

Because if you want to use it in production, I would look for other
possibilities to call Java code from Firebird - Java support in Firebird
3.0 won't be production ready in a year at least, I think.

If you would describe your task more in details, I think we will be able
to give you some suggestions how to solve it with the current features
of Firebird.
