Correct.

"so" or "dll" must be accessible to JVM either through $PATH/%PATH%
variable or java.library.path system property. Currently you cannot
put library into .jar file, we will try to get this in next version
of JayBird.

> 2. can I access it on a "mac os x" system?

Not yet. As far as I know, embedded server is not yet available for
mac os x. Also we do not have a JNI link for mac os x, but that
should not be a problem.
