[xwiki-users] Uploading larger files

Hello xwiki users, I have to upload larger files (i.e. ebooks (above 100MB) or images of 80MB) and at the moment the upload fails. I increased the size of mysql packages to 512 MB, but it didn't help, any ideas? Best regards Pierre

[xwiki-users] Anybody able to deploy Xwiki on glassfish 2.1.1 using mysql?
by Mike 14 Sep '10

14 Sep '10

I've got pristine installations of both mysql 5.1.48 and glassfish 2.1.1, and I always get: PWC1406: Servlet.service() for servlet action threw exception com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load class com.xpn.xwiki.store.migration.hibernate.XWikiHibernateMigrationManager from param xwiki.store.migration.manager.class Wrapped Exception: Could not initialize class net.sf.cglib.proxy.Enhancer at com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:402) at com.xpn.xwiki.XWiki.getXWiki(XWiki.java:471) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:136) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:116) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) at org.apache.catalina.core.ApplicationFilterChain.servletService(ApplicationFilterChain.java:427) at ..... [rest of dump cut] This is annoying, because I was able to get an earlier version of Xwiki going, but had a server crash where everything got wiped out, and I'm starting fresh. Any help would be gratefully received. Many thanks. Regards, Mike

Hello, How can I force (via some admin script or configuration) that a specific user's group have a predefined watchlist? I would like to guarantee that a specific set of pages and/or spaces are being monitored by certain groups. I'm using XWiki 2.4 with LDAP groups for authentication. Regards, Ramon Gomes Brandão

[xwiki-users] Extension Manager first working POC !
by Thomas Mortagne 13 Sep '10

13 Sep '10

Hi xwikiers, Since May and actively since end of August I'm working on a POC for the future (long awaited) Extension Manager. It's now in a state where you can play with it a bit ! So here is a quick advertisement. You can find it on http://svn.xwiki.org/svnroot/xwiki/contrib/sandbox/xwiki-extension/ What it does already: - display remote extension and its dependencies as a tree - install remote extension and its dependencies from repositories - framework support any kind of extension using ExtensionInstaller component interface but only jar installer is implemented right now - framework support any kind of repository using RepositoryFactory component interface but only maven is implemented right now - load installed application when XWiki starts Critical features not yet supported: - miscellaneous rights protections in extension manager script service - uninstall/upgrade support: need to find a way to remove a jar from classloader. Note that you can remove an extension from local repository and restart. - xar installer: just need to provide a ExtensionInstaller implementation with role hint "xar" since this needs access to the whole model the first version will probably be implemented with old APIs (XWikiDocument, etc.) on xwiki-core side - install extension not coming from a repository: the current API is very repository centric but you can do it "by hand" by putting directly the extension jar file in the local repository. - real descriptors in local repository for installed extensions (to store in a repository independent way extension information as well as some local only metadas like the fact that an extension as been installed as a dependency of another etc.) - others on http://svn.xwiki.org/svnroot/xwiki/contrib/sandbox/xwiki-extension/README.t… I'm preparing some design documentation that will go on http://dev.xwiki.org/xwiki/bin/view/Design/ExtensionManagerProposal but i don't have much time right now so it will probably be tomorrow (GMT). The current state is not final at all but it still introduce a lot of APIs and design, lets call it an over designed POC. It needs to be discussed in all it's aspects before having its experimental tag removed. The plan is to distribute it with XE coming with 2.5 whatever it's state (when it does not represent a risk for XE obviously) as an experimental playground with all the required warnings in the UI and promote it when we are happy with a first version. Thanks, -- Thomas Mortagne

[xwiki-users] Strange HTTP://500 error?? hibernate.cfg.xml wrong?
by Kaya Saman 13 Sep '10

Ok I figured this one out!! The pg_hba.conf file of Postgresql needed to have this line added: # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust *host all all 192.168.0.151/32 trust* Now all is fine!! :-) Few!

[xwiki-users] OpenID
by Николай Кучумов 11 Sep '10

11 Sep '10

Hello. Does XWiki support OpenID authentication yet? It would be natural, since a wiki is asually an additional service of some big portal. E.g. a business portal, a gaming portal, a scientific portal. I know you have LDAP authentication, but LDAP is for Enterprise only - i.e. for LAN only. And for Internet you need OpenID. Do you have OpenID authenticator implemented? Or are you planning on it?

[xwiki-users] Hide class template on livetable
by Erica Usui 11 Sep '10

11 Sep '10

Hello! I've tried (without success) some scripts to hide the class template when using livetable. It is said<http://xwiki.475771.n2.nabble.com/Livetable-td4744002.html>that on 2.1+ XWiki versions this doesn't happen anymore; template document is filtered by JSON sources. But I'm using 2.2.1 XWiki version, and I still get the template document appering in the results. I didn't understand the following (which i've tried to use to filter the template): #if ("$!className" != "") #set(${...Sql = ", [snip] and doc.fullName <> '${className}*Template*' [snip]") from the link <http://xwiki.475771.n2.nabble.com/Livetable-td4744002.html>. This is the code which would filter the template, right? Can anyone help me? -- Atenciosamente, Erica Usui.

[xwiki-users] Getting Error number 4001 frequently
by Matthew Hildebrand 10 Sep '10

10 Sep '10

I am frequently (and randomly it seems) getting a 4001 error while parsing velocity page /templates/wysiwyginput.vm when loading pages for inline-edits. This is happening both on fields that have wiki-syntax (2.0) content and fields that while able to take wiki-syntax content, have only plain text. (i.e. "Lengthy, detailed information as needed. A good use of this would be training for new application features. This will be limited to text. If more is needed the user should be redirected to more detailed help documentation.") If the inline-edit page is immediately hard-refreshed (<CTRL>+<F5>), the message usually goes away and the correct content is displayed. However, users often don't notice the problem until 3-5 edits later, once the error message output has been saved to the field. (see log messages below) The setup that I have is: -- Page -- 1 Class Object of type A w/ multiple properties (incl. several textarea fields) -- Many Class Objects of type B w/ multiple properties (incl. several textarea fields) -- Many Class Objects of type C w/ multiple properties (incl. several textarea fields) The problem has occurred for objects from all three classes, and there doesn't seem to be any consistency as to which class/property it happens to. The biggest thing that I can't figure out is that for one load of the page it's fine, then it's broken, then (without changing the underlying data or code) it's fine again. Thanks! --Matt Here is the output from the catalina.out log file: 2010-09-09 18:12:59,874 [http://xwiki.internal.nwresearch.com/xwiki/bin/preview/ProjectManagemen
