programatically grant access rights in the PAR file

Hi All,

First of all, Can we programmatically grant access rights in the PAR file ?

<b>DETAIL</b>: The issue is, "I want to grant rights to the PAR file programmatically, so as to give access to a limited/specific set of users/group of users. If I am able to do this, then the only thing remains is to deploy it, add it to a page and set it for Portal Content, then I don't have to worry about Users privileges (whether they have privilege for it or not)".

I know how to create a PAR file via Eclipse (using Plugins) and how to deploy it.

Thanks In Advance,

Abhishek Jain.
