using jquery in whole application

[saidmsl]

Hi,

i' m using :  http://corebos.org/documentation/doku.php?id=en:devel:add_special_block

to add a block inside the detailview of Account

i have declared jquery in Header.tpl :

<script type="text/javascript" src="include/jquery/jquery-1.11.3.min.js"></script>

but it's not available in the widget 
i have to redeclare it under the <accountwidget>.tpl

<script type="text/javascript" src="include/jquery/jquery-1.11.3.min.js"></script>

so that i can access the $ variable

is it possible not to recall the jquery again:?
