The JNI Specification and Programmer's Guide is indispensible. The
description for the FindClass JNI function mentions J2SE's class-loaders,
so maybe the problem in your native code is that the right class-loader
isn't being used.
You may want to investigate what's going on by writing a plain JNI-free
Java program that asks specific Classes what their ClassLoader is, to get a
better sense of those relationships.
Regarding Java's extensions-dirs, which use class-loaders that are not the
bootstrap-classloader...
JDK 1.4's Endorsed Override dirs:
<http://java.sun.com/j2se/1.4/docs/guide/standards/>
The Java Extensions mechanism described:
<http://java.sun.com/j2se/1.4/docs/guide/extensions/index.html>
Mac OS X Java extensions dirs:
<http://developer.apple.com/qa/qa2001/qa1170.html>
And see Apple's Java examples:

(e.g. simpleJavaLauncher)
