Hi,
I'm trying to install and use XWiki Workspace.
First, the install instructions on 
xwiki.org are not present :
http://www.xwiki.org/xwiki/bin/view/Main/Download#HXWikiWorkspaces, then
"Instructions" link gives
http://workspaces.xwiki.org/xwiki/bin/view/Main/GettingStarted which is not
very intersting, in my opinion.
Second, when I launch xwiki worspace, I see this exception :
00:40:15.011 INFO   [main]
org.mortbay.jetty.servlet.ServletHandler$Context.log(ServletHandler.java:1134)

 16> Plexus initialized.

...etc, etc, etc. I don't know if it is important ?
And, when I look at my workspace, at get :
 Error 404 - Not Found.
No context on this server matched or handled this request.
Contexts known to this server are:
    * WebApplicationContext[/xwiki,xwiki]
The links above may not work if a virtual host is configured 
and, if I clic on the link :
 HTTP ERROR: 404
/xwiki/ Not Found
RequestURI=/xwiki/
