I was on the right track in what I wrote above. I finally found the following reference in the JNI spec (http://java.sun.com/j2se/1.5.0/docs/guide/jni/spec/design.html):
anonymous wrote : "The programmer may use a single library to store all the native methods | needed by any number of classes, as long as these classes are to be | loaded with the same class loader. The VM internally maintains a list | of loaded native libraries for each class loader. Vendors should choose | native library names that minimize the chance of name clashes." The key point here is "same class loader". Not a parent, not a child: Same class loader. We have resolved this problem by loading the native libraries from an MBean and then invoking code during the initialization of the MBean that loads the library *and* touches each class that uses native methods, forcing the classes to be loaded by the MBean class loader. Once we do this, everything works correctly. Note that if you do not force a class with native methods to be loaded by the MBean, it will be successfully loaded later by a different class loader, (for example, an EJB class loader), but the native methods will not be visible. One side effect of this solution is that we cannot hot deploy the classes with the native methods and our code that calls them. We could perhaps achieve some level of hot deployment if we carefully separated our code, but we didn't try.
