[xwiki-users] [Video] XWiki-G3 demo - XWiki cluster storing native Java objects in Cassandra distributed store.
by Caleb James DeLisle 04 Jul '12

04 Jul '12

Hi, Over in the XWiki Research Department, we've been working on some exciting new developments. While XWiki provides industry leading flexibility for defining, storing and querying data structures in SQL based stores, we are researching how to bring storage to Cassandra distributed NoSQL data store and give you the power to define and store your own true Java native Objects. In this demonstration we run 2 integrated XWiki/Cassandra nodes and show changes propagating from one to the other as we edit pages. We show that you can stop one node and the wiki is still fully functional with only one node running. Then we restart the downed node and show the edits which were made while the node was down propagating over from the running node. XWiki documents and objects are stored in an integrated Cassandra NoSQL Cloud data store allowing for horizontal scalability without any single point of failure. Users can define XClasses using the XWiki class creation interface and those XClasses are compiled into native Java classes which can be loaded and stored in the Cassandra distributed store. Here is the demonstration video: https://www.youtube.com/watch?v=NngAKdeWuH0 While this is still in heavy development, we hope to be bringing up live nodes for you to play with as soon as possible. Thanks, Caleb

[xwiki-users] Wiki-fying a database schema / DDL?
by Matt Lamoureux 03 Jul '12

03 Jul '12

Hi all, I'm just starting to use Xwiki, having been the admin for my company's JSPwiki installation for a few years now. In that one, we had a very useful part of the wiki which was an online database schema for our databases. You see a list of the tables, which you can click on and see the list of fields in that table, which you can click on and see the information regarding that field. Our method was to take a DDL and run it through a script which parsed it out into files that JSPwiki could read. This way, we could take updated DDL's, run those through the script, and keep updating the table list and table info pages, while leaving the field named pages untouched. Assuming I have described that correctly, does anyone have any solutions that would be similar to this in Xwiki? Something that doesn't involve manually updating the table list and table info pages? I was thinking we could modify the script to spit out something that we could the import into Xwiki, but I'm not sure if that is the best approach. I was hoping there was a plugin that let you connect to a database and run real-time queries and then us a macro to wiki-fy the results, but I didn't find anything like that. Thanks in advance for the suggestions! - Matt L.

[xwiki-users] You don't have the right to execute this script
by David Delbecq 03 Jul '12

03 Jul '12

Hello, i created a page with a few xwiki code inside it. I can display this page without troubles. I also created a side panel that does simply include that pages. The side panel gives me a macro error org.xwiki.rendering.macro.MacroExecutionException: You don't have the right to execute this script while the main page display without errors :s as suggested here http://xwiki.475771.n2.nabble.com/Groovy-macro-in-a-panel-td7346045.html i tried to remove the dropPermissions() but it doesn't work. What is the solution? Do i have to put my groovy code inside a macros and use the macro in panel instead of including a document containing the code? David Delbecq

[xwiki-users] xwiki object properties not saved
by David Delbecq 03 Jul '12

03 Jul '12

Hello, i have a custom object class + a from and "new" button. When i create an object, using the following code {{groovy}} if(request.doCreate == "true"){ // Request for creating a new instance obj= doc.newObject("Main.NewsClass") obj.set("linkfr",request.thelien) obj.set("titlefr","a test") obj.set("linknl",request.thelink) obj.set("titlenl",request.thetijtle) obj.set("publication",request.thedate) doc.save() } {{/groovy}} the object is created but form properties not saved (please not i hardcoded "a test" and even this property is not saved). Instead i obtain an object with properties all empty. If i remove the calls to set(name,value), the object is saved without properties instead of empty one, so code is somehow partially working? Does someone have any suggestion? David Delbecq

[xwiki-users] XWiki upgrade instructions
by Arioch 02 Jul '12

02 Jul '12

I believe the instruction is incomplete http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Upgrade#HLet27scleanitup I thinks that among other files user should also backup/restore XWiki\WEB-INF\classes\logback.xml if he modified it .... I also think FavIcon is to be preserved. One mast say, it should lie one step in, in Jetty root, but to me i had to have it both in Jetty root and in XWiki root -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-upgrade-instructions-tp7580046.html Sent from the XWiki- Users mailing list archive at Nabble.com.

by Arioch 02 Jul '12

02 Jul '12

i have a brand new XWiki 4.1 install I don't have any xwiki 1.0 documents So i put this configuration: xwiki.rendering.syntaxes = xwiki/2.1, creole/1.0, html/4.01 When i edit the page,., it offer me those formats PLUS xwiki/1.0 Why ? How can i really disable it ? --- I thought that XWiki is largely markup-agniostic... Is GUI editor really uncapable of creole markup ? -- View this message in context: http://xwiki.475771.n2.nabble.com/disabling-xwiki-1-0-markup-tp7579990.html Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] [ANN] XWiki Summer 2012 Hackathon
by Vincent Massol 29 Jun '12

29 Jun '12

Hi devs and community at large, Every year XWiki SAS (http://xwiki.com) gathers all its employees for a Seminar and every year we have an internal hackathon. For example here are the results of last year: http://www.xwiki.com/xwiki/bin/view/Company/Hackathon2011 Previously the Hackathon was a 1 day event only. However this year we're changing the format; it'll run for 8 days! :) Thus we thought it could be a good idea to invite the XWiki Community to join us for a mega distributed Hackathon! So here's how I think we could organize it: * Start date: 20th of July. A mail will be posted on this day to announce the start * End date: 27th of July. A mail will be posted on this day to announce the end * Gathering results: from 28th to 6th of August. Everyone who participated should reply to the end of hackathon mail with what they did and post their stuff on http://extensions.xwiki.org or elsewhere * On around the 6th of August we'll have a blog post written on xwiki.org summarizing all that was done by everyone Those who have participated will also get XWiki T-Shirts. Anyone interested in joining the fun? Thanks -Vincent with my XWiki SAS employee hat
