Add JavaBean to NetBean 3.6---How-to?

I've installed NetBean 3.6, there's alot predefined control in Swing, AWT, JavaBean... category, I can add new category but I can't add anything to that category, I want to add some third-party component to that category to design the GUI (the process is the same as UserCotrol in Visual Studio .NET).
How can I achieve it?
Thank you!

I've tried your way, it worked. But another problem emerged, when I install a new JavaBean, browse to the jar file and NetBean show me a list of all JavaBean in that jar file, but when I drag one of those JavaBeans into a JFrame, NetBean threw an exception said that "Can't instantiate the class...make sure it is a JavaBean...".
I don't understand!
You can get the JavaBeans that I mentioned at
Thank in advance.

Actually, they are JavaBeans not NetBean modules. Thank anyway.
