Problems setting up multiple servers

Hi all, I just downloaded XWiki to evaluate it. From the list of features, it looks like it might be the best out there. But, I can't figure out how to get multiple wikis to work. I pointed two domains at my XWiki server. I created an XWikiServerClass. I created XWiki.XWikiServerDomain1 and XWiki.XWikiServerDomain2 and set their servers to be www.domain1.com and www.domain2.com, respectively with owner XWiki.admin. I set xwiki.virtual=1 and restarted tomcat. It looks like they're both still working out of the "xwiki" database in MySql rather than creating their own database. If I make a change on the wiki in domain1, the same change appears in domain2. They aren't two separate wikis. If I get rid of the www. at the beginning of one of the "server" fields, it redirects to the "This wiki does not exist" page. So, I can't seem to get virtual wikis working. Any ideas? I'd really like to choose XWiki for this (hopefully big) project. Thanks so much!
