UnsatisfiedLinkError with function call

Question

Hi,
I am using JNI to make native function calls from Java.
I use
System.loadLibrary("myLibName");
to load my library, and that works without a problem.
I can use this library without any problems from a simple test app I wrote. However, I get an UnsatisfiedLinkError when I try and integrate with the rest of my applicaton. I am 100% certain that function is defined correctly in both Java and C++.
The only difference I can think of between my real application (which does not work) and my test application (which does work) is that in my real application, the object that makes use of the class that contains all my native methods is cloned before it makes any calls to my native code.
What can cause an UnsatisfiedLinkError if my System.loadLibrary() is correct, and my function definitions are also correct?
Thanks!
Eliott

Answer 1

In case my post needs any clarification, here is some sample code that demonstrates what I am doing:
//An instance of this class gets cloned before any native function calls are made!
public class SomeClass implements Cloneable {
    JniClass jniclass;
    SomeClass() {
           jniclass = new JniClass();
    //This returns an UnsatisfiedLinkError when called
    public void func() {
            jniclass.nativeFunc1();
    public void clone() {
          //Something....
public class JniClass {
    public native void nativeFunc1();
    static {
         System.loadLibrary("myLibName");
