Re: Mac OS X java.library.path

Obviously, your test program is not running code from the
lpsove55j.jar file.  Here, you are trying to load the stub library
directly. This is normally done indirectly by the LpSolve.class. Just
compare the stack traces in both cases. 

Perhaps there is a misunderstanding. System.loadLibrary loads a
*native* library, not a jar file!
