How are you invoking the "aboutPage2" definition? I don't see any action at
all in your struts.xml, nor a result type for Tiles.

Ciao Antonio,
thank you for the response, only today i'm subscribed to the maillist...and
i read the response fortunately viewing the archive mail list...
For invoking the action I used a Convention Plugin for Struts2, i use the
tags into the action.
And I'm sure, before using tiles, the aboutPage2 without using tiles it's
ok, and the jsp was writing entirely into 1 page jsp without any other
"tile", except javascript and css.
This is the code for the action with convention plugin tags:
