Bootstrap panel issue: "Please enter a valid XWoot ID"

Hi Fabio,

I've successfully built and installed the current Concerto prototype. When trying to configure XWoot though, I get the following error in the bootstrap panel when hitting the "Save" button after having filled in the requested parameters:

Please enter a valid XWoot ID (positive integer value).

Parameters:

XWiki endpoint (Ex : http://my.local.dns.fr:8080/xwiki/xmlrpc)
http://concerto-1.forge.mandriva.com:9595/xwootApp/

XWiki user login (Ex : Admin)
Admin

XWiki user password
admin

Datas serialization folder (Ex : c:\tmp\xwootDatas ou /home/toto/tmp/xwootDatas)
/home/concerto/xwoota

XWoot server name (Ex : Chewbacca)
xwoota

Any idea about the problem?

The server can be accessed live at http://concerto-1.forge.mandriva.com:9595/xwootApp/
