[jQuery] jQuery.noConflict() is not working

[jQuery] jQuery.noConflict() is not working


Hi!
I am using following things in separate JS file:
a-
var dom = {};
dom.query = jQuery.noConflict(true);
b-
var jQ = jQuery.noConflict();
c-
jQuery.noConflict();
Neither of above work and Firbug gives error.
But $ works perfectly.
Can some one guide me where I am doing mistake.
Thanks in advance
