****ting a JNI library to Mac/Intel

I have developed a JNI library in Tiger, under CodeWarrior 8, that finds
and opens 
dynamically a native carbon library using FSMakeFSSpec. What is the
pathway to converting 
this JNI library for Mac/Intel processors? Is it sufficient if I build the
JNI lib in 
XCode, or the native carbon library cannot be loaded in this environment?

Thanx
