Thanks!!
i did:
#set($wikidescriptor =
$xwiki.getDocument("xwiki:XWiki.XWikiServer${context.database.substring(0,1).toUpperCase()}${context.database.substring(1).toLowerCase()}"))
now $wikidescriptor.server has exactly what I need! thanks for your help!

Hi, Thanks for the response. But there are still
a couple issues. Here
is a review of my setup again. I have a xwiki manager with a couple
wikis on it. ill call the xem controller wiki "controllerwiki", and
the virtual wikis "wikiA" and "wikiB" This is the code im using:
-------------------------------
#set ($WikiManager = $xwiki.wikimanager)
#set($wikiDesc = $WikiManager.getWikiFromName("wikiA"))
#set($wikiAlias = $wikiDesc.firstWikiAlias)
$wikiAlias
------------------------------
When I put this code in a page called "Test" on the controller wiki, i
get the following:
XWiki.XWikiServerWikiA,wikiA.domain.net,XWiki.Admin
but when i put this code in a page called "Test" in wikiA I get a
stack trace. here it is:
Error number 4001 in 4: Error while parsing velocity page Main.Test

I think this is a bug in wikimanager.getWikiFromName("wikiA"), it
seems it looks in current wiki in place of forcing search in main wiki
for the wiki descriptor (I just added a jira issue
http://jira.xwiki.org/jira/browse/XAWM-88).
1 - A workaround is to get the descriptor "by hand": all wikis
descriptor are in the main wiki with the name
xwiki:XWiki.XWikiServer<Wikiname> with an upper case for the first
character of the wiki name. The velocity code to get the current wiki
descriptor is something like:
#set($wikidescriptor =
$xwiki.getDocument("xwiki:XWiki.XWikiServer${context.database.substring(0,
1).toUpperCase()}${context.database.substring(1).toLowerCase()}"))
and then $wikidescriptor.server give the domain of the first alias (To
get other alias you have to list document's objects of type
"XWiki.XWikiServerClass")
2 - Another solution if your have progrmming rights is simply to
switch to main wiki using $context.setDatabase() before executing
wikimanager plugin code and restore current wiki when it's done:
#set($currentDatabase = $context.database)
$context.setDatabase($context.mainWikiName)
[...]
$context.setDatabase($currentDatabase)
i really need to be able to get the domain name of the wiki im on with
out knowing its name too, so something that takes the name of the wiki
as an arg probably wont work for me. And suggestions? Thanks.
The current wiki is in $context.database

The domain name of a wiki is part of it's descriptor (like the owner
of the wiki etc.) and you can get the descriptor using
$wikimanager.getWikiFromName("wikiName"). Then this Wiki object
contains the list of aliasses of this wiki you can get using
getWikiAliasList() if you want them all or getFirstWikiAlias() if you
just want the one generally used when generating URLs like
[wikiname:Sapce.Page]. Here you can find all you see when you look at
XWiki/XWikiServerWikiname : owner, server, description... and some
helper like serverUrl, homePageUrl etc.
So to sumurize your use case in velocity (given that your wiki name is
"wikiname"):
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
#set($wikiDesc = $wikimanager.getWikiFromName("wikiname"))
#set($wikiAlias = $wikiDesc.firstWikiAlias)
the server url of wiki "wikiname" is $wikiAlias.serverUrl and it's
home page is at $wikiAlias.homePageUrl
