Here is what we trying to do:
Our Java app will generate a username based on firstname+surname and to
cater for possible collisions we need to call destQueryProcessor to check
eDir if the username is already taken.
So basically we will call that java app from XSLT stylesheet which in turn
will call destQueryProcessor function so it can then check eDir and iterate
until name is unique.
Is it possible and if yes how it's can be accomplished.
Some examples will definitely help.

TIA
