upgrading from 3.5 on tomcat6 with mysql and LDAP auth against AD OS is Ubuntu 10.0.4 only "customisation" was in hibernate.cfg.xml for database and xwiki.cfg for LDAP and lucene path backed up database downloaded and unzipped new war file stopped tomcat moved webapps/xwiki to a backup location put the new xwiki in webapps/xwiki edited hibernate.cfg.xml: xwiki.cfg and xwiki.properties to match previous removed the LDAP config apart from xwiki.authentication.authclass=com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl xwiki.authentication.ldap=1 started up tomcat logged in as local admin imported new admin.xar imported all of it, (well I'd upgraded this install quite a few times and wanted a "clean sheet") changed admin user password changed rights to prevent unregistered users imported the new ldap.xar go to setup LDAP get error "LDAP service is not available. Please verify your installation." logout as local admin login as superadmin and get same errror documentation here http://extensions.xwiki.org/xwiki/bin/view/Extension/LDAP+Application links to here http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Authentication#HLDAPAut… which doesn't have anything specific google searches for the error don't have anything remotely useful all pages are in place and database looks good, but the lack of LDAP auth is a bit of a pain any suggestions, or should I go back to 3.5 and upgrade to 4.1.1 without the LDAP .xar ? Cheers Arne

[xwiki-users] Registration and Layout settings resetting
by Ashtar Communications 09 Sep '12

09 Sep '12

Hi, It seems that my wiki is spontaneously resetting several configuration settings, most notably the registration, email, and layout settings. I enter information like the email server, address, and port, which panels to display in the sidebar, or whether to require email verification. After a few hours, I return to the site to find that the panels are turned off, email registration is turned off and the boxes for formatting verification emails, etc are blank, and half of the email settings are cleared. There may also be other configuration options being reset that I haven't found yet. I am the only administrative user on the wiki. It's also definitely not due to vandalism - exactly the same settings disappear every time, and it has now repeated itself 4 times in the last 24 hours. I'm running XEM 4.2m2 on Tomcat with MySQL. Any help would be greatly appreciated... thanks, Aaron

[xwiki-users] [ANN] XWiki Enterprise and XWiki Enterprise Manager 4.1.4 released.
by Denis Gervalle 07 Sep '12

07 Sep '12

The XWiki development team is proud to announce the availability of XWiki Enterprise 4.1.4. This is probably the last bugfix release for the 4.1 series. It provides 30 bug fixes, mainly in the Extension Manager, including important fixes for extensions that provide components or script services (see XCOMMONS-231 andXCOMMONS-232). It also improves the large data migration introduced in 4.0, in particular to support MS-SQL, and fixes an important issue that cause the migration of annotations to be unintentionally skipped. You can download it here: http://www.xwiki.org/xwiki/bin/view/Main/Download Make sure to review the release notes: http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWikiEnterpris… Thanks -The XWiki dev team

[xwiki-users] xwiki talks with the LDAP server for every page access
by Adrian Fita 06 Sep '12

06 Sep '12

Hi. I have an Xwiki Enterprise 3.4 installation and I'm studying the integration with LDAP. I managed to configure the authentication, I created the users and mapped the groups with the LDAP server. But I noticed that the performance dropped dramatically when using LDAP auth, in comparison with local users, specifically it takes around 10 seconds to access a page (down from <3sec). So, I started monitoring the traffic between the xwiki machine and the LDAP machine with tshark and I noticed that every time I click a link in xwiki, there is a lot of traffic with LDAP. Is there some way to improve this behaviour (I really don't understand why xwiki needs to talk with the LDAP server on every page request...)? I see that this is not a new issue [1], [2]. I also tried setting xwiki.authentication.always=0 in xwiki.cfg but I didn't notice any change (it being set to 0 by default already...). Would upgrading to the latest stable version improve the situation? 1. http://lists.xwiki.org/pipermail/users/2011-April/019745.html 2. http://jira.xwiki.org/browse/XWIKI-2516 Thanks for your time. -- Fita Adrian

[xwiki-users] migrating open source projects to WWiki
by Daniel Pocock 05 Sep '12

05 Sep '12

Hi, I have a few sites for various open source projects: http://www.lumicall.org http://www.opentelecoms.org http://www.dynalogin.org They currently run on drupal7. I've never been a big fan of PHP though, and as a Java developer, I'm tempted to migrate them to XWiki or Magnolia. Can anyone make any comment on this choice? Also, can anyone comment on how an open source/community site can get skins for WWiki, similar to the many free skins/themes available for drupal? I've previously run XWiki in a company (back in 2007) and I imagine it has changed a lot since then.... Regards, Daniel

[xwiki-users] Uploading big attachments issue
by Eugen Colesnicov 05 Sep '12

05 Sep '12

I installed XWiki from deb-package. No any changes, only I switched to the filesystem attachment store, and also, I changed upload_maxsize for 1GB limit. All is fine, speed of uploading attachments is great! But when I try to upload attachment with size more than 200mb (aprox.) - I get an error: Caused by: org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. No space left on device at org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:371) at com.xpn.xwiki.plugin.fileupload.FileUploadPlugin.loadFileList(FileUploadPlugin.java:250) ... 41 common frames omitted This problem exists only with one attachment file size is more than 200MB, but I can attach many and many files with 180MB each of them... Also no any problem with disk storage - all mount points have free space (new machine). Can somebody help with this problem? -- Thanks beforehand!

by Nicolas Jouanin 05 Sep '12

05 Sep '12

Hi, I'm runnig Wiki 4.1.3 (Ubuntu 12.04) with a wiki content migrated from Xwiki 3.1. I use postgreSQL 9.1 I'd like to create a xar backup of this migrated content so : - I connect using the Admin user - Go to wiki administration - Content -> Export ( http://localhost:8080/xwiki/bin/export/XWiki/XWikiPreferences?editor=global… ) and xwiki shows a blank page with top menu, logo and footer. The Export form is not shown and no administration menu on right. Tomcat output shows no error except : WARN o.x.v.i.DefaultVelocityEngine - Deprecated usage of getter [com.xpn.xwiki.api.Util.getArrayList] in unknown namespace@794,35 Any idea ? The import page is displayed correctly, but that's not what I want to do. Regards.
