This should happen because when you run your Java program, it cannot find the HelloWorld shared library (.dll, .so... depending on your OS).

Try this to check where the JVM expects you to put the shared library, and place it in one of the directories you see:

System.out.println(System.getProperty("java.library.path"));

Generally, the working directory is a safe choice.
