[xwiki-users] Out of memory error?? Java Heap Space on Tomcat6
by Kaya Saman 03 Jan '12

03 Jan '12

Hi, first up Happy New Year to everyone :-) Secondly, I've been trying to stabilize my Xwiki install on FreeBSD 8.2 x64. My machine is a quad core box with 4GB RAM and not much usage in terms of people viewing the wiki etc.... I am getting this error: umbers=0&rev=11.1" java.lang.OutOfMemoryError: Java heap space Exception in thread "http-8180-Acceptor-0" java.lang.OutOfMemoryError: Java heap space I have attempted a resolution by including: - after Google'ing heavily to see what could be done to rectify the issue. JAVA_OPTS=-Xmx1024m JAVA_OPTS=-Xms1024m #JAVA_OPTS=-XX:PermSize=64M #JAVA_OPTS=-XX:MaxPermSize=256m at the top of the catalina.sh file but as I've just found out it didn't work. The strange thing is that I had this wiki migrated to an old PowerMac G4 733MHz with 384MB RAM and even though the cpu went up to max due to the amount of swap space consumed the system still worked fine for longer then my BSD machine at least. Can anyone give me a hand in order to diagnose the problem? I have tried this also on Nexenta Core 3 (OpenSolaris) on a virtual machine running on my notebook with 2GB RAM dedicated to it which worked fine also and was up for many weeks even though pathetically slow..... actually I was running Glassfishv3 but it was still Java! Thanks, Kaya

[xwiki-users] Problems with attachement store file

Hi all, since I switched from database attachement store to filesystem store I have some problems. The first view days everything was ok, but than i restarted the server and since than: mysql> select * from xwikiattachment; +-------------+-------------+------------------------------------------------------------------------------------+----------+---------------------+----------------------------+-------------+-------------+ | XWA_ID | XWA_DOC_ID | XWA_FILENAME | XWA_SIZE | XWA_DATE | XWA_AUTHOR | XWA_VERSION | XWA_COMMENT | +-------------+-------------+------------------------------------------------------------------------------------+----------+---------------------+----------------------------+-------------+-------------+ | -2139505400 | -1980029764 | Assertions.pdf | 0 | 2007-05-17 23:19:13 | XWiki.RobertReiner | 1.1 | | | -2136668642 | -1260324256 | groups.png | 498 | 2009-09-03 17:38:38 | XWiki.Admin | 1.1 | | | -2096787253 | -152317460 | XWikiLogo.png | 1390 | 2009-09-09 02:00:00 | XWiki.Admin | 1.1 | | | -2083635922 | 1934194131 | msginfo.png | 0 | 2008-11-14 16:46:06 | XWiki.AntonKronseder | 1.1 | | | -2027337590 | -259212042 | general.png | 0 | 2010-09-18 03:19:58 | XWiki.Admin | 1.1 | | | -2003457988 | 151244875 | xwiki-enterprise-manager-wiki-administrator-1.5.1.xar | 0 | 2009-02-27 12:24:23 | XWiki.Admin | 1.1 | | Some files in the storage folder are empty (have size 0) as stated in XWA_SIZE have in the database. The ~METADATA.xml file states, that the size is 0. Are negative IDs OK (e.g. for XWA_ID) ? Sometimes, when I copy manually the correct file with size > 0 to the store and when I change the ~METADATA.xml accordingly it works, sometimes not. Sometimes when I upload an image with a German name (e.g. Wüste.jpg [is desert in english]) it is stored and also named desert.jpg. I guess some information (rdf) inside the jpg (some jpg metadata) knows, that its name is desert.jpg. Am I guessing right? I have 312 attachements in our xwiki. Do I have to delete the database tables (xwikiattach*) and do the attache process again? Files that xwiki does not know e.g. mytest.abc can be attached. They can be found in the store and are listed in the view but I can not receive tha file. Not by clicking on the attachement link, nor by rightclicking and choosing "save link as". BTW in between I had to change the server (hardware) and had to install a new xwiki. Afterwards I imported the Files (using xar import) and did a filesystem copy of the store. All Pages are OK, all attachements are listed, but can not be downloaded, besides the ones in the original xwiki.xar, which I also imported. Any suggestions? Thanks in advance.

Hello, Happy new year to everyone. I'm trying to have the email of an user and I want to put it on every document the user creates. For that, I try this two differents codes : #set($mail=$xwiki.getUser($doc.getCreator(), false).getEmail()) and an other try : #set($user=$xwiki.getUser($doc.getCreator(), false)) #set($mail=$user.getEmail()) But none of this two codes is right. What should I do to have the email of my user ?

[xwiki-users] Same session is getting associated from separate IE windows while login?
by mohit gupta 03 Jan '12

03 Jan '12

Hi All, I do the login with admin credentials in one internet explorer window. Now i open one more seperate IE window and give my xwiki home url i.e http://localhost:8888/myxwiki/ . I see in this second i am directly getting logged in with admin credentials which is not correct. I should see login screen on this second window here. Then i did debugging and found out with both IE windows xwikicontext.getRequest().getSession() returning the same session( basically both sessions are having same session id). As per my understanding session is specific to browser window . so both windows(or request from diffent IE windows) should have different session attached to them. Not getting how come both request are having same session id. Thanks

[xwiki-users] Help with links: xwiki:$s:MyPage and History for Quicklinks-Panel and login problem loginsubmit
by Anton Kronseder 03 Jan '12

03 Jan '12

Hi all, perhaps someone has the same problem (hopefully already solved): After migrating from 1.x to 2.x and now to 3.1 and 3.2 I have some problems :-( a) All links to the xwiki Main-Space look like the following example: xwiki:$s:MyPage regardless if I use [[Main.MyPage]] or [[MyPage]] the only solution would be: [[MyPage>>Main.MyPage]] If the page is not in the xwiki Main-Space everything works fine. b) My Quicklinks Panel look horrible: <https://www.smartics.eu/xwiki/bin/view/Administration/ServerAdministration> Looks like it is in xwiki 1.0 Syntax, but 2.0 is expected. Is there a possibility to get to the history of the quicklinks panel, to restore my old one? Is there a posibillity to change the xwiki syntax for a panel? c) And last but not least After logging in I am forwarded to: http://www.smartics.eu/xwiki/bin/loginsubmit/XWiki/%2Fxwiki%2Fbin%2Fview%2F… Looks like to be an apache problem, but i use ProxyPass to forward (proxy) all to my tomcat and RewriteEngine to redirect https: 80: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} ProxyPass /xwiki http://www.smartics.eu:8080/xwiki ProxyPassReverse /xwiki http://www.smartics.eu:8080/xwiki 443: ProxyPass /xwiki http://www.smartics.eu:8080/xwiki ProxyPassReverse /xwiki http://www.smartics.eu:8080/xwiki What happens: I go to http://www.smartics.eu/xwiki I am redirected to https://www.smartics.eu/xwiki I do the login: and than I am forwarded to http://www.smartics.eu/xwiki/bin/loginsubmit/...... And here somehow the redirect to https does not work and the page can not be delivered, as apache states "Not Found". Looks like both (Rewrite and ProxyPass) are pypassed somehow. But when I now enter manually (in the same browser) "https://www.smartics.eu/xwiki" I am logged in. Any idea what might be wrong? Any help to my problems would be highly appreciated. Best wishes for the new year. Best regards, Anton Kronseder

[xwiki-users] Extending XWiki collaboration toolset
by coldserenity 02 Jan '12

02 Jan '12

Hello, Since XWiki is positioned as a collaboration tool, where collaboration is primarily on the documents, sooner or later there will emerge a need to provide functionality similar to what Google Docs has: simultaneous editing of documents, supporting text documents, spreadsheets (with ability to generate charts, calculating subtotals), presentations, embedding spreadsheet tables and charts into documents etc. - at least several times I found myself in a need to do manual table-based calculations and to simultaneously work on the document. One more possible improvement is support rich brainstorming sessions like in e.g. http://incubator.apache.org/projects/wave.html (integration?) So I was wondering, are there any plans for those directions?

Heading levels can be off when a big document (PDF) is composed of many included topics. Is ther a way to adjust the level of headings in the included topic?

[xwiki-users] Polls Application installation with Extension Manager issue
by coldserenity 28 Dec '11

28 Dec '11

Hello, Recently I've tried installing Polls Application ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Polls+Application ) via Extension Manager and received error listed in the file attached: http://xwiki.475771.n2.nabble.com/file/n7130006/InstallPollsExtensionError.… InstallPollsExtensionError.txt . The odd thing is the success message in the end of the file (I have added info and error macro markup to show how it looked like on the screen). Polls Application pages got created and I was able to create polls. With bugs but they worked. Questions: * Is the error during installation of the application important one or should be ignored? * I had to manually configure the l18n bundle after the installation - should I log an enhancement for EM to auto-configure it during installation? * Should I log any bugs I observe in Polls Application (and where to)?

[xwiki-users] styling PDF and ODT export
by petskratt 28 Dec '11

28 Dec '11

I have been trying to apply styles to PDF (and hopefully also ODT) export according to instructions in http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Configuration#HCustomiz… but... (1) adding CSS (either as pdf.css or via PDFClass & PDFTemplate method) that contains simple test (h1, h2, h3 {color: red;}) does not work (tested on XE 3.3 release) (2) at the same time, changing xhtmlxsl (either by adding to PDFTemplate or WEB-INF/classes) works nicely Q1: Should it work with CSS? The abovementioned instruction expects this method to work also with RTF export - and as the ODT export is based on PDF export I hoped to be able to style also ODT... but even when change is working in PDF headings remain black in RTF and ODT export... as these XSL transforms seemt to be related to FOP used for PDF generation. Q2: How to style ODT export? Also with pdf.css (that doesn't currently work), somehow modifying default template used by OpenOffice or somehow with OpenOffice.xsl? -- View this message in context: http://xwiki.475771.n2.nabble.com/styling-PDF-and-ODT-export-tp7116069p7116… Sent from the XWiki- Users mailing list archive at Nabble.com.
