Struts & Scaffold question

[kaspar minosiants]

Hi !
I've started to explore struts recently and now i'm looking into Artimus
example . So what i see is that through all this aplecation a lot of
Jakarta Commons pacages are used and one of them is Scaffold . It hides
original struts implementation . So i bump into several questions is it
common practice to use this pacage or there there are a lot of
alternatives or it's more recomendet to use struts and write my own
implementation. If Scaffold is a good thing to use where can i found
more matireal about it ?

Thanks a lot in advance !
