public class HelloWorldJNI {
 
    static {
        // Loaded with RTLD_GLOBAL flag
        try {
            LibraryLoaderJNI.loadLibrary("/path/to/my_native_lib_A");
        } catch (UnsatisfiedLinkError e) {
            System.Println("Couldn't load my_native_lib_A");
            System.Println(e.getMessage());
            e.printStackTrace();
        }

        // Not loaded with RTLD_GLOBAL flag
        try {
            System.load("/path/to/my_native_lib_B");
        } catch (UnsatisfiedLinkError e) {
            System.Println("Couldn't load my_native_lib_B");
            System.Println(e.getMessage());
            e.printStackTrace();
        }
    }
    
    public static void main(String[] args) {
        new HelloWorldJNI().sayHello();
    }
 
    private native void sayHello();
}
