by Julien Hervouet 21 Sep '11

21 Sep '11

Hi, As an adept of freemind I was very happy to see that a freemind macro exist for xwiki. Unfotunately I have a ClassNotFoundException when tha applet is invoked by the macro, it seems that the FreeMind java library can not be found by the downloaded applet. Here is the Stack Trace of the exception : /Java Plug-in 1.6.0_15 Utilisation de la version JRE 1.6.0_15-b03 Java HotSpot(TM) Client VM charger : classe freemind.main.FreeMindApplet.class introuvable. java.lang.ClassNotFoundException: freemind.main.FreeMindApplet.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:http://code.xwiki.org/xwiki/bin/view/Macros/freemind/main/FreeMindAp… at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception : java.lang.ClassNotFoundException: freemind.main.FreeMindApplet.class/ The exception occurs on my instance of xwiki and on the xwiki web site at this example address : http://code.xwiki.org/xwiki/bin/view/Macros/MindMapMacro My instance of xwiki is XWiki Enterprise 1.9.3.22597 on Windows XP SP3 and as you see in the stack trace I have the last 1.6.0_15 java plugin.

[xwiki-users] Why the "created" and "last modified" time are wrong?
by flyisland 23 Jul '11

23 Jul '11

Hi All, I have installed "XWiki Enterprise 2.2.1.27354" on my laptop, and found that after created or modified the document, the "created" and "last modified" time are wrong! For example, my local time is "2010/04/28, 22:08", but the "date" of the document I just created is "2010/04/28, 09:38". My local time zone is "Beijing, China", UTC/GMT +8 hours. How could I solve this issue? You comments are welcome! Island

[xwiki-users] Clobbered syntax when importing 2.1 xwiki content into 2.5.1
by Lars Lindwall 20 Jul '11

20 Jul '11

Hi, I'm having severe trouble when importing xwiki content from xwiki 2.1 into xwiki 2.5.1. When the import is fresh everything seems OK: http://xwiki.475771.n2.nabble.com/file/n5808169/original.jpg When I try to edit, the syntax looks exactly as in 2.1 http://xwiki.475771.n2.nabble.com/file/n5808169/edit.jpg And when I "Save & Show" (without any changes) the page looks like: http://xwiki.475771.n2.nabble.com/file/n5808169/new.jpg What is this? How can I get around this?

[xwiki-users] component manager not initialized after install
by Scott McMasters 19 May '11

19 May '11

Hello, I installed XWiki today and when I first tried to view the Wiki, I received the following error: Error 500: Component manager has not been initialized before lookup for [org.xwiki.model.reference.DocumentReferenceResolver] for hint [currentmixed] Could anyone give me advice about this error message? I installed it on Websphere AS 6.1, fix level 23, and Oracle 9g. I modified the Hibernate config file to use Oracle with "OracleDialect" pointing at my database. I also added the dummy data source. I added the PNG mime-type and restarted WAS. I added ojdbc41.jar to the WEB-INF/lib folder of the WAR. I did change the Web app context to "wiki" instead of "xwiki", but I didn't think that should make a difference. Thanks in advance, Scott McMasters

[xwiki-users] Add a user on a User List property
by Jean Couteau 02 May '11

02 May '11

Dear all, I have a class with a UserList attribute. I am trying to add users to this list from an other page with no success. I try using the following code : #if($joinTask!="") #set($taskDoc = $xwiki.getDocument("Project.${joinTask}")) #set($taskObj = $taskDoc.getObject("XWiki.TaskClass")) #set($list = $taskObj.get("assignedPeople")) $list.add($xwiki.getUser()) $taskObj.set("assignedPeople", ${list}) $taskDoc.save() #end but $list.add does not exist so I tried differently : #if($joinTask!="") #set($taskDoc = $xwiki.getDocument("Project.${joinTask}")) #set($taskObj = $taskDoc.getObject("XWiki.TaskClass")) #set($list = $util.getArrayList()) $list.add($xwiki.getUser()) $taskObj.set("assignedPeople", ${list}) $taskDoc.save() #end but I have a casting exception. I had a look on the velocity website, on this list archives,... with no success My question is : Can I add users like that or the only way is through the edit panel and if yes, what is my mistake ?

[xwiki-users] XWiki going out of resources
by Andreas Hahn 23 Mar '11

23 Mar '11

Hi XWiki users, fwiw I just want to share my experiences and observations with XWiki instance running out of memory. I was having a hard time to track this down but in the end I could successfully isolate the problem. For quite some time my XWiki instance was getting unresponsive to requests sooner or later. The Wiki was hosted on a VirtualBox VM and in most cases the VM guest was just freezing and needed to be restarted leaving no usable traces in the logs. In some cases I even found JVM crash reports so I first checked different JVMs and VirtualBox versions (PUEL and OSE licences). I had no success with this approach and so I moved the XWiki directly to a host environment (Ubuntu 10.10). I added Server instrumentation (VisualVM) but still the wiki got down after a while. Surprisingly the system was hanging although in many cases there was even enough memory available (I checked different VM settings up to 4GB). Finally a VisualVM thread dump showed what happened: When the robots came visiting my service they query a large number of pages and among them was one user-url: .../XWiki/someUser which ran into an infinite looping condition when rendering the page. I don't know how this could happen but as a result the whole memory was consumed and partly released afterwards so it seemed that there is still enough space available. Once this happened however the Webserver needed to be restarted because it wasn't responsive any more. Since I have deleted this user account everything is running ok for a couple of days now - I still have to move the service back into the VirtualBox guest VM. What puzzles me finally that its possible that one single request can kill the service by going into an infinte rendering loop. I would have thought that at some level there is a depth limit to prevent such conditions. Hope these observations help someone though .... enjoy Andreas

[xwiki-users] Dynamically set rights over document
by Lukapt 09 Mar '11

09 Mar '11

Hi, I'm trying to set rights over a document automatically. In my wiki i have the "Publication" concept. Each Publication has one or more authors. Each author is an "Researcher" that is directly related to an XWikiUser. What I want to do is to set editing rights only for the authors of that publication. If I add (or remove) an author he should be able (not able) to edit the document. What i thought first was to check and add user rights every time the document was loaded. However this didn't worked because, initially, users don't have rights to add new rights (lol). That doesn't seemed a good practice anyway. What is the best way to do this? Maybe after every change in editing mode, system may apply the rights? How can I do that? Btw, I'm using this snippet to add the user rights: http://extensions.xwiki.org/xwiki/bin/view/Extension/Setting+Rights Thanks in advance, Luís Braga -- View this message in context: http://xwiki.475771.n2.nabble.com/Dynamically-set-rights-over-document-tp60… Sent from the XWiki- Users mailing list archive at Nabble.com.
