I've followed Sun's "The Java Native Interface" by Sheng Liang on
creating a JNI test/example. Unfortunately it isn't working for me.
This leads me to believe that either I'm doing something stupid or
things have changed in later versions of Java.

Environment information:
$ java -version
java version "1.4.2_16"

The below source code is taken directly from the book. Here is my
HelloWorld.java file:

class HelloWorld {
    private native void print();
    public static void main(String[] args) {
        new HelloWorld().print();
    }
    static {
        System.loadLibrary("HelloWorld");
    }
}

Here is the HelloWorld.c file:

#include <jni.h>
#include "HelloWorld.h"
#include <stdio.h>

JNIEXPORT void JNICALL Java_HelloWorld_print(JNIEnv *env, jobject obj)
{
    printf("Hello World!\n");
    return;
}

Steps to build:

$ javac HelloWorld.java
$ javah -jni HelloWorld
$ gcc -O2 -fPIC -pthread -W -Wall -Wno-unused -Wno-parentheses -pipe -
D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_REENTRANT -D_LITTLE_ENDIAN -
D_LP64=1 -c HelloWorld.c
$ gcc -z defs -Wl,-O1 -Wl,-soname=libHelloWorld.so -static-libgcc -
shared -mimpure-text -o libHelloWorld.so -lc

Run the Java app:

$ java -Djava.library.path=. HelloWorld
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/
sprotsman/workspace/HelloWorldJ2/libHelloWorld.so: /home/sprotsman/
workspace/HelloWorldJ2/libHelloWorld.so: cannot open shared object

       at java.lang.ClassLoader$NativeLibrary.load(Native Method)
       at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1586)
       at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1511)

       at java.lang.System.loadLibrary(System.java:834)
       at HelloWorld.<clinit>(HelloWorld.java:7)

Any help on what I'm doing wrong would be much appreciated.
