[xwiki-users] Out of memory error
by AmzSid 16 Jul '09

16 Jul '09

I have the following error occuring. I really like XWIKI but this memory issue is the only stumbling block. I would hate to have to move to daisycms or jspwiki. I have installed xwiki onto tomcat on Linux. Memory params are: -server -Xms512m -Xmx768m -Xss512k -XX:+UseParallelGC XWIKI config settings are out of the box ones. I did upload an excel spreadsheet attachment and then decided to delete it. I also tried to export to PDF, RTF etc. and left XWIKI running overnight and got this problem in the morning. 2009-07-15 08:20:24,351 [ http://localhost:8080/xwiki/bin/view/Sandbox/TableTraining?xpage=xpart&vm=c… ] [http-8080-Processor21] WARN web.XWikiAction - Uncaught exception: Error number 0 in 11: Uncaught exc eption Wrapped Exception: java.lang.O}}}utOfMemoryError: PermGen space 2009-07-15 08:23:14,716 [] [http-8080-Processor21] ERROR [/xwiki].[action] - Servlet.service() for servl et action threw exception java.lang.OutOfMemoryError: PermGen space 2009-07-15 08:58:03,385 WARN [service.services.export.ExportService] Backup directory /opt/tomcat/logs/backup does not exist Exception in thread "DefaultQuartzScheduler_QuartzSchedulerThread" java.lang.OutOfMemoryError: PermGen space 2009-07-15 10:50:24,583 [http://localhost:8080/xwiki/bin/view/Main/] [http-8080-Processor21] WARN web.XWikiAction - Uncaught exception: Error number 0 in 11: Uncaught exception Wrapped Exception: PermGen space 2009-07-15 10:50:48,298 [http://localhost:8080/xwiki/bin/view/Main/] [http-8080-Processor19] WARN web.XWikiAction - Uncaught exception: Error number 0 in 11: Uncaught exception Wrapped Exception: PermGen space 2009-07-15 10:51:59,029 [] [http-8080-Processor21] ERROR [/xwiki].[action] - Servlet.service() for servl et action threw exception java.lang.OutOfMemoryError: PermGen space 2009-07-15 10:52:36,721 [] [http-8080-Processor19] ERROR [/xwiki].[action] - Servlet.service() for servl et action threw exception java.lang.OutOfMemoryError: PermGen space java.lang.OutOfMemoryError: PermGen space Exception in thread "http-8080-Processor22" java.lang.OutOfMemoryError: PermGen space 2009-07-15 11:59:54,765 [http://localhost:8080/xwiki/bin/view/Sandbox/] [http-8080-Processor25] WARN web.XWikiAction - Uncaught exception: Error number 0 in 11: Uncaught exception Wrapped Exception: PermGen space 2009-07-15 11:59:59,377 [] [http-8080-Processor25] ERROR [/xwiki].[action] - Servlet.service() for servl et action threw exception java.lang.OutOfMemoryError: PermGen space Exception in thread "main" java.lang.OutOfMemoryError: PermGen space

[xwiki-users] Difficulties on first launch workspaces
by Hervé Agnoux 15 Jul '09

15 Jul '09

Hi, I'm trying to install and use XWiki Workspace. First, the install instructions on xwiki.org are not present : http://www.xwiki.org/xwiki/bin/view/Main/Download#HXWikiWorkspaces, then "Instructions" link gives http://workspaces.xwiki.org/xwiki/bin/view/Main/GettingStarted which is not very intersting, in my opinion. Second, when I launch xwiki worspace, I see this exception : 00:40:15.011 INFO [main] org.mortbay.jetty.servlet.ServletHandler$Context.log(ServletHandler.java:1134) >17> resource = file:/home/herve/onwork/xwiki-workspaces-distribution- hsqldb-1.1.1/webapps/xwiki/WEB-INF/plexus.xml 00:40:15.178 INFO [main] org.mortbay.jetty.servlet.ServletHandler$Context.log(ServletHandler.java:1134) >16> Plexus initialized. java.lang.UnsatisfiedLinkError: /home/herve/java/jdk1.6.0_14/jre/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1695) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1028) at sun.security.action.LoadLibraryAction.run(LoadLibraryAction.java:50) at java.security.AccessController.doPrivileged(Native Method) at java.awt.image.ColorModel.loadLibraries(ColorModel.java:188) at java.awt.image.ColorModel.<clinit>(ColorModel.java:196) at com.jhlabs.image.WholeImageFilter.<init>(WholeImageFilter.java) at com.jhlabs.image.WaterFilter.<init>(WaterFilter.java) at com.octo.captcha.engine.image.gimpy.DefaultGimpyEngine.buildInitialFactories(DefaultGimpyEngine.java:503) at com.octo.captcha.engine.image.ListImageCaptchaEngine.<init>(ListImageCaptchaEngine.java:493) at com.octo.captcha.engine.image.gimpy.DefaultGimpyEngine.<init>(DefaultGimpyEngine.java:494) ...etc, etc, etc. I don't know if it is important ?

[xwiki-users] about to give in...
by Edward Eldon 15 Jul '09

15 Jul '09

Hi I have noticed that there has been more activity in the last couple of days ... so, here's one last attempt. I have got to the stage where a captcha field is shown, and the page (registerinline.vm) displays the correct errors if it isn't filled in (some simple if statements) However, the user is STILL registered even if the captcha is filled in wrongly. I have searched this news group, experimented and given up ... but if anyone can suggest how to stop this my xwiki user would really appreciate it. Happy to post code if anyone's interested! thanks - hopefully Edward

[xwiki-users] How to fully delete a Space?
by Loris Conedera 15 Jul '09

15 Jul '09

Hi All, I have some problems to fully delete a Space from Xwiki, I think there is a not update cache of pages list that contains moved/deleted pages, here what i did: I tried to move all pages from the space "A" to the space "B" and to delete A.WebHome. In this way it seems that the space is fully deleted and if I try to open the url: https://intranet.test.com/xwiki/A/ I get the message "The requested document could not be found", as i expected. The problem is that the "A" space yet appears in the "listo of spaces" that i can select in "Search", "Lucene Search", "Index", "Tree"... If I Search in space "A" i get some name of pages but if i click on them i get the "The requested document could not be found" message because i moved them on space "B" Can you let me know where i'm wrong? is there any way to delete the indexes that contain the space list? If not, Can i work directly on database? Thanks! Loris

[xwiki-users] WYSIWYG editor link function cannot work
by ArielWang 15 Jul '09

15 Jul '09

I update XWIKI from 1.1 to 1.8 and I need to keep some VM. All JS files are imported into the editor and it seems all functions are correct except the "link" ->"wiki page". When I click "link" -> "wiki page" shown below: http://n2.nabble.com/file/n3254443/image001.png It always showing "Loading data……", see the screenshot below: http://n2.nabble.com/file/n3254443/image003.png I find the problem is some code cannot be parsed: https://www.denver.com/xwiki/bin/edit/Test/$request.getContextPath()/rest/w… The italic words are contents cannot be parsed. The right URL should be:http://www.denver.com/xwiki/rest/wikis/xwiki/spaces?r=788517 I think $request.getContextPath() should be parsed to: http://www.denver.com/xwiki ; and $context.getDatabase() should be parsed to: xwiki I don't know whether I am right or not. Is there anybody can point out the problem why the code cannot be parsed correctly? I will be so appreciated! -- View this message in context: http://n2.nabble.com/WYSIWYG-editor-link-function-cannot-work-tp3254443p325… Sent from the XWiki- Users mailing list archive at Nabble.com.
