jq mobile want work with local js- and css files

hi, 

i store the jquery-1.9.1.min.js, the jquery.mobile-1.2.0.min.js and the jquery.mobile-1.2.0.min.css in /lib/js and /lib/css

at my index.html i put these in the header:

  1. <link rel="stylesheet" href="lib/css/jquery.mobile-1.2.0.min.css"/>
  2. <script src="lib/js/jquery-1.9.1.min.js"></script>
  3. <script src="lib/js/jquery.mobile-1.2.0.min.js"></script> 
but no jq mobile works. if i replace it with (from your homepage):

  1. <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" /> <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script> <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script> 
it works perfekt.

what is my  mistake?

thx
