Resolving jQuery conflicts

I’m a newbie on jQuery… when i integrate tons good wordpress plugin, it’s always a nightmare because there is always had var conflicts, so there have a function call jQuery.noConflict(); for solving such kind of conflicts, you just modify the control script to jQuery(foo) instead of $(foo), cool?

  <html>
  <head>
  <script src="prototype.js"></script>
  <script src="jquery.js"></script>
  <script>
    jQuery.noConflict();
    // Use jQuery via jQuery(...)
    jQuery(document).ready(function(){
        jQuery("div").hide();
    });
    // Use Prototype with $(...), etc.
    $('someid').hide();
  </script>
  </head>
