[xwiki-users] Java Heap Space, Out of memory exception
by Ajdin Brandic 11 Jun '10

Hi All I am having a problem uploading a xar file. I get "Java Heap Space, Out of memory exception" (full message below). I've downloaded the latest version of XWiki for windows xp (beginner's version with HSQLDB & Jetty). In my start_xwiki.bat I have set "set JAVA_OPTS=-Xmx1600m -Xms512m". 1.6gb is the maximum as xwiki would not start if I go over this. I don't think I have CATALINA.bat any ware so I din not find where to set CATALINA_OPTS. I have changed file upload size to 133MB by going to http://localhost:8080/xwiki/bin/edit/XWiki/XWikiPreferences?editor=objec t and changing Maximum Upload Size:. The .xar file is 90MB downloaded as backup from http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Main/WebHome. I do not know what version this runs on since it is on one of the xwiki farm things :-). I have Win XP with 3.5gb memory available. Has anyone had this error recently? Regards Ajdin Brandic Here is the full error message: A problem occured while trying to service your request. Please contact the support if this happens again.

[xwiki-users] XWiki Instalation

Hi, I'm trying to install xwiki following all the steps included in http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMySQL. I'm working with jboss and MySQL. * First I download xwiki-enterprise-web-1.9.3.war then, * I installed MySQL 5.1 in this step I created the Data base - mysql -u root -e "create database xwiki" - mysql -u root -e "grant all privileges on xwiki.* to xwiki(a)127.0.0.1 identified by 'xwiki'" - I included the MySQL JDBC Driver JAR in the WEB-INF/lib folder - I changed hibernate.xml with mysql properties * I installed jboss-4.0.5.GA - I tried to use a datasource but doesn't work for me, so I am working without it. As you see, I followed all the steps described in xwiki site, but I have many errors and I haven't done nothing different 16:47:20,204 INFO [DefaultLoadEventListener] Error performing load command org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xpn.xwiki.doc.XWikiDocument#104408758] 16:47:20,375 WARN [XWiki] Exception while getting wiki preference [macros_languages] java.lang.NullPointerException 16:47:20,469 WARN [XWiki] Exception while getting wiki preference [macros_velocity] java.lang.NullPointerException 16:47:20,547 WARN [XWiki] Exception while getting wiki preference [macros_groovy] java.lang.NullPointerException 16:47:42,032 WARN [XWiki] Exception while getting wiki preference [macros_mapping] java.lang.NullPointerException 16:47:43,313 INFO [DefaultLoadEventListener] Error performing load command org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xpn.xwiki.objects.classes.BaseClass#-629142642] 16:47:56,048 INFO [DefaultLoadEventListener] Error performing load command org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xpn.xwiki.doc.XWikiDocument#-1905796263] 16:47:56,439 WARN [XWiki] Exception while getting wiki preference [backlinks] java.lang.NullPointerException I supposed that all of this errors are happening because I have to install the *.xar files And then I got this error and that's all.

Re: [xwiki-users] Formula Macro - rendering methods
by Marine JULIAN 04 Jun '10

Hello, As I didn't find a solution about my native renderer problem issue, so I tried the google charts API one. Unfortunatly, when I write more than a certain number (not too many) of characters in formula tags, I have an error. Instead of using the google charts renderer, the snuggletex one is used... For instance when I wrote this simple code : {{formula}} 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111\\ 111111111111111111111111111111 {{/formula}} All break lines (\\) weren't rendered. But ! If I write only the four first lines, all is fine. Is this a know issue ? What can I do ? Last question : : When my wiki is local, can it make external HTTP ? Because, When I want to use the mathtran renderer I have this error : 2010-04-23 15:49:26,238 [ http://localhost:8080/xwiki/bin/tex/Public/FormulaMacro Again/440bdc8f8001d9d387dbb95e1f1328998c35678a03e22bbf8eb747dc9de8a34d] ERROR web.XWikiAction - Connection aborted See Google Charts renderer error lines : 2010-04-23 12:04:37,463 [ http://localhost:8080/xwiki/bin/view/Public/FormulaMacroAgain] ERROR formula.FormulaMacro - Invalid renderer: [googlecharts].

[xwiki-users] Treeview in a panel
by Sebastian Kannengiesser 02 Jun '10

02 Jun '10

Hi guys, I found a code snippet on xwiki.org, that does a TreeNav feature, but actually, this is not what I want. I would like to have the Treeview, as on /XWiki/Treeview inside a panel. As a matter of fact, it seems the code for Treeview does only work, when there is nothing else on that page, so adding just a line of text in the beginning of the XWiki/Treeview page seems to make the "+"-signs to open the tree-structure unusable. Probably for the same reason, I did not manage yet, to get it inside a panel. Do you have some ideas, what I could do to get what I want? Thanx, Sebastian

[xwiki-users] preventing registration on workspaces under xem
by Daniel Svoboda 17 May '10

17 May '10

Hi, I'm using workspaces 1.2M1 as a virtual xwiki under xem 1.3. I have configured the XWikiServerClass object under XWikiServerServername to have the visibility property set to 'Private'. When I look at XWikiPreferences in the virtual xwiki, there are XWikiGlobalRights objects configured Deny, Groups:,Levels:Register,Users:XWikiGuest, and Deny, Groups:XWikiAllGroup, Levels: edit, register, Users: The registration form still appears on the login page, and upon filling in the fields and submitting, registration is successful. I need to not allow registration by anyone except Admin. Thanks, Dan Svoboda

[xwiki-users] Deny Public registration Wiki Workspaces
by Chris Ellis 13 May '10

13 May '10

I really love the look and use of the xwiki products, but the lack of documentation and broken functionality is very frustrating. After finally getting smtp authorisation working in Enterprize I find the email which is generated is not forming URLs properly - grrr. So now I'm back to exploring Workspaces milestone 1.2 and I have found that setting Public Registration to Allow or Deny makes no difference - registration is just a matter of supplying a name and email address and you're in. No admin approval required. This is not acceptable for an admin setup intended for staff only. Can anyone explain to me how this might be fixed please? Cheers Chris Ellis Lorne-Aireys Inlet P-12 College

[xwiki-users] colorThemeInit and updating theme problem
by Ben Stuggler 05 May '10

05 May '10

Hello, I would like to have a specific color theme for my users depending of the groups. So I modified the colorThemeInit.vm to check the user group and apply a specific theme. My problem is after logging, I have to refresh the page manually to see the new theme, even if I click on a link in the wiki. How can I force a refresh automatically after logging? Should I call the template colorThemeInit somewhere else ? Thanks Regards Ben -- View this message in context: http://xwiki.475771.n2.nabble.com/colorThemeInit-and-updating-theme-problem… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] PDF export - Footer/Header/View
by Wilson Leão Neto 03 May '10

03 May '10

Hello all! I'm working with XWiki and I'm a newbie... I've read the tutorial available on http://code.xwiki.org/xwiki/bin/view/Modules/RenderingModule and the customization part of the pdf export. I'm still clueless on how to do it properly... I have java experience, so I can code what is necessary, I just don't know where to go. All I want to do is change the default template. Changing the footer, header, TOC and breaking a page on every h1 found. I would be glad if someone could give me a hint. Thank you, Wilson

[xwiki-users] [Security Advisory] SQL injection issue.
by Caleb James DeLisle 03 May '10

03 May '10

In the 2.3 timeframe, a serious security bug was fixed. Hibernate treats backslashes differently from some database management systems and as a result native SQL can be injected through the searchDocuments function. This means members of a wiki can finish an SQL query, also this means that badly written searchDocuments or search queries go from small security issues to larger ones. NOTE: Passwords are hashed (encrypted) so they cannot easily be read from the database. Who's at risk? Database systems which treat backslash as an escape character and allow stacked queries are susceptible to arbitrary SELECT, INSERT, UPDATE, DELETE, and DROP statements. These include: MS-SQL Postgres Database systems which treat backslash as an escape character but disallow stacked queries are susceptible only to arbitrary SELECT statements. These include: MySql Oracle Database systems which do not treat backslash as an escape character are not vulnerable these include: HSQLDB (default XWiki zip/exe installation) You can get a small groovy snippet to test your database and see if it supports stacked queries here: http://dev.xwiki.org/xwiki/bin/view/Drafts/SecuringXWiki#HMitigationMethods… What can be done: #1: XWiki-2.3 and XWiki-2.2.6 Are patched to convert \ to \\ in search queries so upgrading to them will negate the threat. You can download them here: http://www.xwiki.org/xwiki/bin/Main/Download #2: If you compile your own branch of XWiki and are unable to upgrade, you can integrate the patch which was used to fix the problem The patch is here: http://dev.xwiki.org/xwiki/bin/download/Drafts/SecuringXWiki/XWIKI%2D4755%2… Since the database controller has changed, you will likely have to port this patch to your version, what's important is that api.XWiki.searchDocuments and api.XWiki.search have their input filtered. #3: You can and should make sure to log unexpected SQL at the database level. XWiki doesn't usually use the backslash character and queries containing backslashes should be logged specially. Also it is a good idea to log (or block if possible) any SQL comment syntax. Hibernate does not support comments and comment syntax is central to almost all SQL injection. Caleb
