This document would answer the question: "show me the films > with Richard Gere". Indeed, or another possible option would be to add a property "playsIn" of type "Database list" to the class "Person". The query associated with that property would be something like the one below, for fetching all the Media titles: ====== select distinct prop.value from BaseObject as obj, StringProperty as prop where obj.className='XWiki.Media' and prop.id.id = obj.id and prop.id.name='title' order by prop.value ====== Or third possibility: simply use plain wiki links between the documents: create three documents "Richard Gere", "Pretty Woman", "Autumn in New York", attach structured objects to each of them, then add a link to "Pretty Woman" and "Autumn in New York" to the body of the document "Richard Gere". I hope this helps. By the way, this type of question should rather be submitted to the xwiki-users mailing-list! -> I propose we continue the discussion on that list instead.

Adding virtual wiki's (copied from Nabble)
by Esbach, Brandon 30 Apr '07

30 Apr '07

Hello, I have managed to get 3 wiki's going the "main one" and two virtual wikis. First up, this message is not readable by the group, as there is a problem with your Digital Sig. That's beyond the scope of this mail list though, so you may need to contact your IT folks directly to fix that. From what I see here, it looks like you've added it correctly. Are you sure that the case, spelling, etc are identical in the server field and in the actual name (see /xwiki/bin/view/Xwiki/XWikiServerXwikiemansio in the address field of your browser to confirm this - the X from xwikiemansio should be in caps even in the link)? -----------------------COPIED POST----------------------- I set-up both of the two virtual wikis "at the same time". Trying to add a third virtual wiki....it is not recognized as a virtual wiki.... This is what I did to add my third virtual wiki: 1. I created the DNS record for emansio.fireventures.com to CNAME "my wiki host" 2. I created a DB schema in mySQL called xwikiemansio 3. Added full access rights to this schema for the xwiki db user in mySQL 4. I created a page called: /xwiki/bin/view/Xwiki/XWikiServerXwikiemansio 5. To this page I attached an object called: XWiki.XWikiServerClass[0]: emansio.fireventures.com 6. I set the server to emansio.fireventures.com 7. and the owner to XWiki.Admin 8. I then restarted Tomcat Trying to reach http://emansio.fireventures.com/xwiki/bin/view/Main/ I get redirected to the "this wiki does not exist page" in my main wiki.... Any ideas are highly appreciated..... // Jan Eldenmalm ---------------------END COPIED POST---------------------

problems with jackrabbit
by gyoergy.magoss＠bhf-bank.com 30 Apr '07

30 Apr '07

Hi, we are looking for a java based wiki. XWIKI seems to fulfill most of our requirements. The only drawback seems, that we are bound to using ORACLE as the database. Since this does not worked I tried a file based approach using jackrabbit. The installation (ond tomcat 5.5.23) was no problem. When I go to the man page the system starts to create the file repository but suddenly falls over with the Exception shown at the bottom of this message. I checked the archives but couldn't find a hint as to how to solve this problem. The classes Field and NodeIndexer that seem to cause the problems are definitely loaded from the libraries deployed in the lib directory of XWIKI (checked with Class.forName(sClassName).getProtectionDomain().getCodeSource().getLocation().toString() for each class in a jsp I deployed into the XWIKI-application. Has anyone an idea what the reason for this problem is and/or how to solve it? Using MySQL or any other database than ORACLE is a no go.

[ANN] XWiki 1.0 RC 3 Released
by Vincent Massol 29 Apr '07

29 Apr '07

The XWiki development team team is pleased to announce the availability of the 1.0 RC 3 release. Go grab it on http://www.xwiki.org/xwiki/bin/view/Main/Download This release is planned to be promoted as the final 1.0 release next week if no critical bug is found till then. New in this release: Bugs fixed: * Filter conflict: external links can be rendered two times. This fixes a problem with some absolute URLs in wiki pages that make XWiki hang. * The link to the user profile is broken for non-local users * Links to virtual wikis broken when using XWiki behind a proxy * The top menu entry shadow disappears when hovering * Generated PDF loses paragraphs Improvements: * Make password type HASH by default IMPORTANT: XWiki 1.0 RC 2 and RC 3 fix an important security issue in past releases where passwords were stored in clear in the database. Passwords are now hashed. If you are upgrading from a previous version, any new user or any password update will automatically get the password hashed. However existing users who do not change their passwords will still have their passwords in clear in the database. Thus, we are providing a tool to automatically hash all passwords from an existing database. See the full release notes on http://www.xwiki.org/xwiki/bin/view/ Main/ReleaseNotesXWiki10RC3 Enjoy -The XWiki development team

Oracle Installation
by Maarten.De-Booy＠ec.europa.eu 28 Apr '07

28 Apr '07

Hello, I followed Ludovic Dubost his Oracle Installation notes. I think that he missed a modification to the xwiki.cfg. In there the xwiki.store.hibernate.path points to the /WEB-INF/hibernate.cfg.hsql.xml instead of /WEB-INF/hibernate.cfg.xml. I installed it on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. It seems to work without a problem. Then I also have a question. Can you define a different port for the Email server? We do not use port 25 and therefor we can not use the Email notification. Regards, Marco
