In fact, I did it in the "Informations Meta HTTP" of the preferences and it
worked.
Thank you for the answers

  Hi,
 I don't manage to put a favicon for xwiki. Any clues ?
 
 Well, a favicon is usually placed in the root of the URL, like
 
www.myserver.com/favicon.ico
 Doing that in a java webapp container usually involves adding that file
 not to the xwiki webapp, but to the ROOT webapp. In tomcat, there is a
 ROOT directory inside webapps.
 Another solution is to put something like this in
 webapps/xwiki/skins/albatross/htmlheader.vm:
 <link rel="icon"
href="$xwiki.getSkinFile("favicon.png")"
 type="image/png"/>
 <link rel="shortcut icon"
href="$xwiki.getSkinFile("favicon.png")"
 type="image/png"/>
 and put a favicon.png (you can change the name, if you want) in
 webapps/xwiki/skins/albatross
 If you're not using the albatross skin, change the path accordingly.
