Using (Installing) Jena in Netbeans

When  I first tried to use Jena in Protégé, I was quite confused... I couldn't compile my code and I wasn't sure if my code was wrong or if hadn't installed the right jars in Netbeans.... So, after searching in the web I 've found this great video (I don't know what language is this... but I managed to understand finally) that explains how to use Jena in Netbeans IDE.
