I have no problem loading jaybird21.dll from JAR file - corresponding
code was already implemented, but there was no big need for it (code
simply extracts DLL from JAR into %TEMP% and loads the library). However
this does not solve your problem - jaybird21.dll has to load
fbembed.dll, which in turn loads other DLLs, that's where the issue with
pathes appear.

firebird.conf will not be loaded from classpath - it is the
configuration of Firebird loaded from fbembed.dll. It has nothing to do
with Java.

...and loads the rest of DLLs from there.

However, I think, the best option would be to "merge" (statically link)
the jaybirdXX.dll, fbembed.dll, icu*.dll and fbintl.dll into one library
and load this big library from Java. But that's completely different
project and, personally, I would estimate need for "Embedded Firebird
for Java" as very small.
