Determining the path to a Library

[John J. Boyer]

I am usinng the library as part of a cross-platform Java application 
(BrailleBlaster). I know where the library is in relation to the .jar 
file, but I can't depend on it's being loaded in any absolute path. It 
will not be loaded with autotools, but will simply accompany the .jar 
file. It referencees its data in a path relative to itself. So the 
problem is either to tell it the absolute path or have it discover it.
