hmm, i remember i had the exact same problem two or three years ago. sadly i
cannot remember the exact cause. but i do remember how i went on to solve it.
its been a while and i cannot reproduce it but i think this is what i did:

i wrote a java program that tried to open a socket to the firebird server i
tried to connect to.
program failed to connect , so i knew it was a java problem rather than i
jaybird problem.
the i opened my debugger ans stepped through the jdk code.
then at some point in the jdk code, and this is what i can not recall, it was
clear to see what the problem was....

this is a very very vague description, i know. but maybe it helps in finding
your problem.
