[xwiki-users] Fwd: Getting the domain name of a virtual wiki through velocity
---------- Forwarded message ---------- From: mh <[email protected]> Date: Wed, Sep 17, 2008 at 11:44 AM Subject: Getting the domain name of a virtual wiki through velocity To: XWiki Developers <[email protected]> Hi, I have an XEM set up with with several virtual wikis on it. I'm trying to get the name of the virtual xwiki though velocity. For example, say that I have a XEM instance running two virtual wikis: 1) wikiA.domain.org 2) wikiB.domain.org on a XEM called xem.domain.org Im looking for the velocity code that will return the name (domain name) when embedded in a page of one of the virtual wikis. Something like: $xwiki.getServerName() if i put that in a page in wikiA, it should return "wikiA.domain.org". Likewise, if i put the same code in wikiB, it should return "wikiB.domain.org" I looked at the velocity code for xem.doman.org/xwiki/bin/view/WikiManager/ because it lists the actual domain names under the "Domain Names" column. But it just gets a list of any virtual wikis available and lists them out. This page uses the xwikimanager plugin. I looked at the api and didn't see a way to directly get the domain name of the wiki in question. Could someone please point me in the right direction? Thanks in advanced and have a great day! -mh

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 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Hello! My XWikisite has two errors: 1. Treeview working properly, but subdocuments (the documents) have no link. When I ask for the link location with the right mouse button I get the message: javascript: YAHOO.widget.TreeView.getNode ( 'treeview', 23). toggle () You can see here: http://apleti.normala.hr/xwiki/bin/view/XWiki/Treeview 2.Tableview regularly works in Mozilla, but in IE table is empty. For example: http://apleti.normala.hr/xwiki/bin/view/XWiki/Tableview What could be causing these problems. I will be grateful to any help. Regards, Sime S.
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 Wrapped Exception: Failed to evaluate content with id Test

Hi,
I have an XEM set up with with several virtual wikis on it. I'm trying to get the name of the virtual xwiki though velocity. For example, say that I have a XEM instance running two virtual wikis:
1) wikiA.domain.org 2) wikiB.domain.org
on a XEM called xem.domain.org
Im looking for the velocity code that will return the name (domain name) when embedded in a page of one of the virtual wikis. Something like: $xwiki.getServerName()
if i put that in a page in wikiA, it should return "wikiA.domain.org". Likewise, if i put the same code in wikiB, it should return "wikiB.domain.org"
I looked at the velocity code for xem.doman.org/xwiki/bin/view/WikiManager/ because it lists the actual domain names under the "Domain Names" column. But it just gets a list of any virtual wikis available and lists them out. This page uses the xwikimanager plugin. I looked at the api and didn't see a way to directly get the domain name of the wiki in question. Could someone please point me in the right direction? Thanks in advanced and have a great day!

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

---------- Forwarded message ---------- From: mh <[email protected]> Date: Wed, Sep 17, 2008 at 11:44 AM Subject: Getting the domain name of a virtual wiki through velocity To: XWiki Developers <[email protected]>
Hi,
I have an XEM set up with with several virtual wikis on it. I'm trying to get the name of the virtual xwiki though velocity. For example, say that I have a XEM instance running two virtual wikis:
1) wikiA.domain.org 2) wikiB.domain.org
on a XEM called xem.domain.org
Im looking for the velocity code that will return the name (domain name) when embedded in a page of one of the virtual wikis. Something like: $xwiki.getServerName()
if i put that in a page in wikiA, it should return "wikiA.domain.org". Likewise, if i put the same code in wikiB, it should return "wikiB.domain.org"
I looked at the velocity code for xem.doman.org/xwiki/bin/view/WikiManager/ because it lists the actual domain names under the "Domain Names" column. But it just gets a list of any virtual wikis available and lists them out. This page uses the xwikimanager plugin. I looked at the api and didn't see a way to directly get the domain name of the wiki in question. Could someone please point me in the right direction? Thanks in advanced and have a great day!
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 < < < < < < < < < < < <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

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! -mh On Sat, Sep 20, 2008 at 7:44 AM, Thomas Mortagne <[email protected]> wrote:

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:

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

---------- Forwarded message ---------- From: mh <[email protected]> Date: Wed, Sep 17, 2008 at 11:44 AM Subject: Getting the domain name of a virtual wiki through velocity To: XWiki Developers <[email protected]>
Hi,
I have an XEM set up with with several virtual wikis on it. I'm trying to get the name of the virtual xwiki though velocity. For example, say that I have a XEM instance running two virtual wikis:
1) wikiA.domain.org 2) wikiB.domain.org
on a XEM called xem.domain.org
Im looking for the velocity code that will return the name (domain name) when embedded in a page of one of the virtual wikis. Something like: $xwiki.getServerName()
if i put that in a page in wikiA, it should return "wikiA.domain.org". Likewise, if i put the same code in wikiB, it should return "wikiB.domain.org"
I looked at the velocity code for xem.doman.org/xwiki/bin/view/WikiManager/ because it lists the actual domain names under the "Domain Names" column. But it just gets a list of any virtual wikis available and lists them out. This page uses the xwikimanager plugin. I looked at the api and didn't see a way to directly get the domain name of the wiki in question. Could someone please point me in the right direction? Thanks in advanced and have a great day!
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 < < < < < < < < < < < <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Hello!
My XWikisite has two errors:
1. Treeview working properly, but subdocuments (the documents) have no link. When I ask for the link location with the right mouse button I get the message: javascript: YAHOO.widget.TreeView.getNode ( 'treeview', 23). toggle () You can see here: http://apleti.normala.hr/xwiki/bin/view/XWiki/Treeview
The Treeview requires programming rights. You need to save the page as an Admin user
2.Tableview regularly works in Mozilla, but in IE table is empty. For example: http://apleti.normala.hr/xwiki/bin/view/XWiki/Tableview
We've seen this issue on IE when you are not an admin. I've posted a bug http://jira.xwiki.org/jira/browse/XE-309
What could be causing these problems. I will be grateful to any help. Regards, Sime S.
