$xwiki not always available?
by Thomas Drevon 30 Jul '07

30 Jul '07

Hi! I've made a panel that displays tags in a tag cloud (size relative to occurrence). But on a few occasions I get an exception, and I've managed to pinpoint fairly accurately under what circumstance. The code involved, that usually works is this: #set($query = "select elements(prop.list) from BaseObject as obj, DBStringListProperty as prop where obj.className='XWiki.TagClass' and obj.id=prop.id.id and prop.id.name='tags'") #set( $allTags = $xwiki.search($query)) #set( $allTagsSorted = $xwiki.sort($allTags)) If the user is not logged in, and presses the login link in the top left corner (--> /xwiki/bin/login/XWiki/XWikiLogin), the panel returns the enclosed exception. After some debugging, it seems that $allTags is not assigned a value from $xwiki.search($query). This leads me to believe that $xwiki might not be available from this particular context. Has anyone else encountered this, or is it an artifact in my environment? I'm running xwiki v1.1-milestone2, mysql, winxp, tomcat, java5. Both my db and xwiki installs are pretty fresh and un-tampered with. best regards :-) Thomas 13:47:50,211 ERROR http-9080-2 http://myHost:9080/xwiki/bin/login/XWiki/XWikiLogin?xredirect=http%3A%2F%2F…

Fwd: External link to same server
by Lee Meador 30 Jul '07

30 Jul '07

Resend ---------- Forwarded message ---------- From: Lee Meador <lee(a)leemeador.com> Date: Jul 16, 2007 2:48 PM Subject: External link to same server To: xwiki-users(a)objectweb.org The links documentation tells how to add a link to another wiki page and a link to a URL like http://yahoo.com I would like to link to a URL that isn't inside the xwiki application but is on the same server without putting in the hostname or ip address. If I was doing this in html, I would use "<a href="/otherapp/home">Other App</a>. I tried the form [/otherapp/home] and simply /otherapp/home but those don't generate the right link. (The first comes out as a link to an xwiki page. The second comes out as plain text.) Is there a way to do this? Thanks. -- -- Lee Meador -- -- Lee Meador Sent from gmail.

Authentication using LDAP and user names with dots
by Eric ter Haar 30 Jul '07

30 Jul '07

I already tried to post this question earlier via the ObjectWeb Sympa interface, but did not see it back in the archive list, nor did I get a e-mail confirmation. So please excuse me if it is posted twice now. I am currently evaluating XWiki for deployment in my company. So far everything looks great, but I ran into a blocking issue. I have setup XWiki to authenticate with LDAP, which is a requirement for us. The user names provided by our LDAP server all have dots in them, like 'eric.ter.haar'. XWiki seems to have a problem with this. When login in for the first time it creates a new user name that is equal to the part after the last dot, e.g., 'haar'. And it creates a space with the other part, like 'eric.ter'. The next login fails but without any notice. Does anyone know how to get around this? Thanks, Eric

Deploying XWiki in shared hosting
by Fernando Lozano 26 Jul '07

Oi, Simple question: is that possible? Or are security manager configurations (Tomcat Sandboxed) make impossible to tune to run current XWiki (1.0)? []s, Fernando Lozano

Sandbox login
by Fernando Lozano 26 Jul '07

26 Jul '07

Hi there, This is a silly question, but I can't find anywhere on xwiki.org which is the sandbox login and password. But the xwiki.org registration states we should not register to use the Sandbox. []s, Fernando Lozano

Section Editing Problem
by Ni Yue 26 Jul '07

26 Jul '07

Hi, I just switched from MediaWiki and installed XWiki 1.1m3, and I found section editing and collaborative editing one page in xwiki is not so well supported compared with MediaWiki. And I have several questions: (1) Instead of using h2 tag to automatically add a section editing icon, could I manually tag a paragraph as a section and edit it? (2) Even if I divide the whole page into several sections with h2 tag, when different users edit different sections in one page, xwiki still indicates someone locks the page, is it possible to get smaller lock granularity and lock just the section rather than the whole page? I think wiki is a collaborative tool, and editing one page in the same time is a very important functionality and should be well supported.Anysuggestion is appreciated, thanks. Regards,

Change of SVN externals for trunks-users
by Vincent Massol 26 Jul '07

26 Jul '07

Hi, I'm about to modify the SVN externals definition for trunks-users so that they point to our own XWiki readonly SVN repo instead of pointing to the OW repo as there are issues with it. If you have checked out trunks-users, then do a svn update once I've made the change. Hopefully that'll just work. If not, you might need to do a new checkout. Sorry for that Thanks -Vincent

Re: [xwiki-users] Section Editing Problem
by Ni Yue 26 Jul '07

26 Jul '07

Hi Vincent, This feature isn't implemented. Is that something Mediawiki does? MediaWiki does not support manually annotating a section, but MediaWiki will automatically divide all html head titles(h1, h2 ...) into a section, so the granularity of a page is relatively small, and conflict will happen rarely, while in Xwiki, only " 1.1" tag will generate a section to edit. This is a bug. Would you mind creating a JIRA issue for it? (in the > XWiki Platform project - http://jira.xwiki.org) Issue created. http://jira.xwiki.org/jira/browse/XWIKI-1531 Regards, Yue

RE: [xwiki-users] Virtual wiki
by diaga＠nomade.fr 26 Jul '07

Hi Brandon, Your idea sounds good. I'm gonna try it to see if it works on local configuration. If not I will have to do all the tests on our server and that what I don't want. Thanks and Bye If you're working local, that could be why. I've never tried this setup extensively myself; but I have known the hosts file to work in certain circumstances for the same thing (using a name to access an IP address). Have you considered using something like Winproxy to provide DNS services? There is usually a free trial available as well, so you needn't pay to test the scenario. -----Original Message----- From: diaga(a)nomade.fr [mailto:diaga@nomade.fr] Sent: 23 July 2007 12:01 To: xwiki-users Subject: RE: [xwiki-users] Virtual wiki Hi Tim, Thank you for your answer. I was afraid that the only solution is using DNS. But at least, I am sure now that this is the only solution. Bye Diaga, I had the same problem and the way I solved it, and only way I know, is having a DNS. Look into the archive for the advice I recieved. Also, make sure you granted the rights for both databases on your relational database.

I used apache and the hosts file of windows to make virtual hosts pointing on the xwiki controller. I have no DNS, I am working on local. In the near futur, I will have an pûbmlic IP adresse and no DNS or subdomain. I am a little confuse. If someone can help because I am really lost.

Lets say I have this 2 line text file called Hello.txt. Hello world. goodbye world. How can I display the contents of this file on a page? I believe I can do it with page.setTextArticle(article);. However, I am a newbie to xwiki and I am still in the dark. What is the full code snippet to use? Thanks in advance. carlos
