NetBeans code helpers?

I was wondering if there’s a way to enable some code helpers for jme3 and netbeans like when I type something like

Geometry g = new Geometry(

and it shows me all possible constructors with variables needed? The same would be good if I write a function name, press “(” and it shows me parameter syntax I need to enter.

Something like when I type rootNode and press “.” it is showing me:

Ctrl-Space, as written in the jMP documentation. For constructors, you have to position your caret directly behind theopening bracket.
