hi all,
	i reply with a fast solution (unfortunately not what i want)

so far, a solution that i found stores variables in the session, and in the
java class of the custom tag, using 
pageContext.getSession().getValue(....) i can get the value of an attribute
however, i would like to do what i showed below....
if it can be possible, how can i do that????
htanx in advance & regards
	marco
