iView parameter who can be rescrued into a portal application

Hi,

I would like to :

- set a parameter to an iView (into the portal administrator interface, when the portal administrator defines the iView's properties).

- and when the iView is called by an user, I would like to be able to rescrue this parameter with the application (JSP / Servlet who runs into the iView).

Is it possible ?

Which property can I use to do this ?

Thanks for your answers
