geodan: Can you explain how you're trying to run WorldWind? Is it from the command line? On what operating system?
On Windows, a minimal WorldWind setup is:
I can run the basic WorldWind demo by executing:
Directory of C:\test

On Windows, Java looks in the current working directory for the native libraries. As nlneilson pointed out, this may not be the case on other systems. You can specify the native library directory with the -Djava.library.path flag, as in:
C:\test>java -jar worldwind.jar
C:\test>java -Djava.library.path=. -jar worldwind.jar
