[xwiki-users] Migrating Xwiki
by Kaya Saman 17 Sep '10

17 Sep '10

Hi, I'm wondering if it's possible to migrate Xwiki from one system to another?? I currently run Xwiki on a FreeBSD 8.0 RELEASE x64 platform with 4GB RAM in a dedicated FreeBSD Jail, however I'm having an issue with Java spinning up the CPU to 100% rendering Xwiki inoperable! If I migrate it would be from FreeBSD to either a dedicated FreeBSD system or an OpenSolaris based system on Nexenta. Currently I run Tomcat6 coupled with Postgresql, but would migrate to Glassfish and MySQL. Is it just a matter of backup the Xwiki from the web GUI then restore under Glassfish and convert database from Postgresql to MySQL then attach at other end? Or can I just simply dump the /webapps/xwiki folder into Glassfish or another instance of Tomcat? Thanks for any advice!! Regards, Kaya

[xwiki-users] Table styles
by adoro 15 Sep '10

15 Sep '10

Hello community, how can I create tables that would have different background colours for odd and even table rows with the new WYSIWYG (like it was in old vers.1.0 Syntax .wiki-table?). Or is there the appropriate macro?

[xwiki-users] SpaceExplorer (treeview) in xWiki Enterprise 2.4
by Zuzana Zapletalova 15 Sep '10

15 Sep '10

Hello, I upgrade my xWiki to 2.4 and I have a problem with SpaceExplorer. It doesn't work. When I try to use it, xWiki returns an error: XWIKIEXPLORER.JS DEPENDS ON XWIKI.JS In the older version of xWiki everything works fine (2.2). I was going through the js scripts and the structure is the same as it was in xWiki 2.2. Does anybody know where is the problem? Thanks, Zuzana.

[xwiki-users] XWiki SQL Plugin
by afra 15 Sep '10

15 Sep '10

Hi @all, did one of you guys get the SQL-Plugin to work with 2.4? I did everything the installation instructions said to do. Even made a sample jsp page which worked just fine with querying the database and displaying my table. But usage of the plugin in any xwiki page doesn't work. Even when using such stupid query as select '1' as 1, '2' as 2 there does not seem to be any resultset returned which i could display via velocity script. Is there any trick i don't know or is the plugin simply broken? Thx -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-SQL-Plugin-tp5530893p5530893.html Sent from the XWiki- Users mailing list archive at Nabble.com.

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 13 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

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! Regards, Kaya -------- Original Message -------- Subject: Strange HTTP://500 error?? hibernate.cfg.xml wrong? Date: Mon, 13 Sep 2010 16:23:37 +0300 From: Kaya Saman <kayasaman(a)gmail.com> To: XWiki Users <users(a)xwiki.org> Hi, as some of you guys who've already helped me know by now that I have a working instance of Xwiki.... Recently I tried to simulate this and go over the steps I'd already done in order to document the install! I installed FreeBSD 8.0 Release x64 and recreated my FreeBSD jail that I currently run Xwiki in. Everything went to plan with all steps involved being documented all the way and versions of software checked against each other; however, when it came to actually browsing to Xwiki I got an error 500 message?? All details of my install can be found here: http://wiki.optiplex-networks.com/xwiki/bin/view/FreeBSD/XWiki however it is quite long so I am only going to explain about the error and areas that the error highlights: I'm using Postgresql as the DB backend as I had issues with MySQL so that needs further testing later, and Tomcat6. My hibernate.cfg.xml file looks like so:  <property name="connection.url">jdbc:postgresql://localhost:5432/xwiki</property> <property name="connection.username">xwiki</property> <property name="connection.password">xwiki</property> <property name="connection.driver_class">org.postgresql.Driver</property> <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property> <property name="connection.pool_size">2</property> <property name="statement_cache.size">2</property> <mapping resource="xwiki.hbm.xml"/> <mapping resource="feeds.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> With the rest all commented out apart from the default non-database stuff right at the top of the stock file; the default DB lines have been commented out! Although no need I uncommented this line: xwiki.store.hibernate.path=/WEB-INF/hibernate.cfg.xml in the xwiki.cfg file. This is the exact error: javax.servlet.ServletException: 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: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: Could not create a DBCP pool.

Has anyone got any ideas of what I'm missing here and why the system claims that there is an error in the hibernate.cfg.xml file?? These are the versions of Postgresql connector that I have tried: postgresql-8.2-511.jdbc4.jar postgresql-8.3-603.jdbc4.jar postgresql-8.3-606.jdbc4.jar On my production build I use 8.3-603.jdbc4.jar On the test version I also installed some patches for the JDK environment as I hadn't updated my ports tree before building the packages even though upgrading the ports rebuilt all the installed packages by removing them first so I don't know if the patch has been applied again or not??? Anyway, fact is that somethings wrong and I need to get to the bottom of this :-) Many thanks for any help! Regards, Kaya
