So glad you took the time to read the download page carefully before posting 
Welcome dadabehh,
here is a link to good tutorials how to get jME started. I can only advise to get it via svn-checkout cause
the package to download is not uptodate anymore. (Nevertheless it works).
The tutorials:

e.g. the eclipse tutorial is straight forward and all you have to do is go through the instruction LINE BY LINE! 
Then it will guide you to the best java3d engine yet.
So good luck and give it a try…
