Using jQuery noConflict yet results in "Uncaught TypeError"

Question

I'm using vticker inside a wordpress blog. Page source is very messy, but I can confirm jQuery is running!! Neither noConflict nor jQuery() instead of $ works out of error.

Clues to finding a solution are really appreciated.

Code:

j$ = jQuery.noConflict();
j$(function($){
    j$('ul.site-wide-stream.swa-activity-list').vTicker({ 
        speed: 500,
        pause: 3000,
        animation: 'fade',
        mousePause: false,
        showItems: 6
    });
});
