> I have to port an application developed in Java (and using JayBird and embedded Firebird) from Windows to Mac OSX...I've found some documentation all around but, being a newbie with Mac world, I get a little bit confused and don't know how to put it to work. I need some sort of "step by step" guide, starting with the files that must be downloaded and installed...any help ?

First issue that you will have, is the JNI wrapper for Jaybird on Mac OS
X. We do not provide binaries for this platform and I have no idea
whether the C++ code that we have there is compilable there.

On the other hand, you could use standalone Firebird server (which
exists for Mac OS X, AFAIK) and connect to the server using TCP. That
might be the easier approach.
