[Xapian-devel] Re: Java Bindings on a Mac

[John Schult]

Well, thanks to a colleague I figured it out...  The Apple JVM looks
for libraries in
/System/Library/Frameworks/JavaVM.framework/Libraries/ and does not
seem to care about -Djava.library.path or LD_LIBRARY_PATH.  There is
probably some environment variable that it does examine, but I stopped
trying to figure it out.

The solution was to:

- Copy built/libxapian_jni.so to
/System/Library/Frameworks/JavaVM.framework/Libraries/libxapian_jni.jnilib
(note the extension)

After that it worked as advertised...

$ java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-113)
Java HotSpot(TM) Client VM (build 1.5.0_06-68, mixed mode, sharing)
