03 May '10

Hello! while I've been frustrated form installing mediawiki... I found XWIKI....The installation was easy and straight-forward then I encountered with an excellent tool for my job: I am not a administrating and I don't want Online wiki so much (at least for 1-2 year)... currently I just need a wiki for my personal use: 1) is XWIKI a good choice for someone like me? 2) I need LaTeX support is it available? 3) I'm a newbie ( I just know a little HTML...) is XWIKI a good alternative for my personal DMS? 4) I've installed my XWIKI on Fedora 11 in /home/user/.XWiki folder is it possible to reinstall it? 5) I can't access my xwiki via menu's shortcut I've to cd .XWiki and "sh start....sh" It works but I want a total solution 6) where do my pages store? excuxe me for this long list question Thanks!

[xwiki-users] XEM - access issue to wiki instances
by Marine JULIAN 03 May '10

03 May '10

Hello, I installed XEM (version 2.3) from a distribution with Tomcat 6.0.26 and MySQL 5.1 on Windows XP. I followed the guide installation. After creating a new wiki instance, I tried to access it but unsuccessfully... I have some delay timeout expiration and wiki can't be displayed. I can only access to the main wiki. I don't know where to look for and what to do, do you have any suggestions ? When I imported the xem application xar, I had these error messages in Tomcat console : ERROR util.JDBCExceptionReporter - Incorrect string value: '\xC5\xABs va...' for column 'XWD_CONTENT' at row 1 ERROR .AbstractFlushingEventListener - Could not synchronize database state with session and after those, some like this one : ERROR packaging.Package - Failed to save document Sandbox.WebHome Do you think it's linked ?

[xwiki-users] Include pages in an other one
by Ben Stuggler 30 Apr '10

30 Apr '10

Hi, I made two Forum with the Bulletin Board. I wondered if it's possible to display the twice Forum (the Webhome?) on a same page, and not just a link. Like this, it's possible to create different forum/space with different rights for users. I tried these solutions but it doesn't work {{velocity}} #includeInContext("Forum1.WebHome") #includeInContext("Forum2.WebHome") #includeForm("Forum1.WebHome") #includeForm("Forum2.WebHome") #includeTopic("Forum1.WebHome") #includeTopic("Forum2.WebHome") {{/velocity}} Thanks Regards.

Hi, I use the stat application and I would like to show the most active contributors to the user. But I would like to show stats to the user only on the users of the same group. I'm a beginner in XWiki and I thought use directly in a document a query seems like $xwiki.search("select distinct docu.author from XWikiDocument as docu where doc.author != ''", 0, 0) Could you help me?

Hi there, maybe it's just a very simple solutiuon I'm not seeing yet, however, I'm wondering if it's possible to create a short *internal* link to a user-profile? Sure, I can create an externel link incl. protocoll etc., but I'd rather have an internal link. Any hints?

[xwiki-users] XWIKI, JNDI datasource and Tomcat 6
by Thomas Fröhlich 28 Apr '10

28 Apr '10

Hi all, I have installed XWiki 2.2.3 in a Tomcat 6.0.20 servlet container using Oracle 10g as database. The database connection settings are done on the default way in the WEB-INF/hibernate.cfg.xml file. XWIKI is running without any problems or exceptions. Now I want to "replace" the database settings in hibernate.cfg.xml by using a Tomcat container managed JNDI data source. The advantage for us is the usage of Tomcat's server.xml as a central place where we can manage all data sources of every webbapp within Tomcat. I have red the articles under http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HInstallan… and http://java.dzone.com/articles/xwiki-installation-jboss-using (it's a JBoss relatet documentation but many information pieces are usefull for Tomcat too). My JNDI configuration is as following: a) definition of the JNDI datasource in Tomcat's server.xml (defining the Oracle JNDI resource can't be the problem because we use other Oracle JNDI data sources without any problems) <Resource name="jdbc/XWikiDS" auth="Container" type="javax.sql.DataSource" username="XWIKI" password="*************" driverClassName="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:@myoraserver:1521:MYORAINSTANCE" connectionProperties="useUnicode=true;characterEncoding=utf8;" maxActive="10" maxIdle="2" maxWait="5000" testOnBorrow="true" validationQuery="SELECT 1 FROM DUAL" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" /> b) settings in xwiki/WEB-INF/hibernate.cfg.xml <property name="connection.datasource">java:/comp/env/jdbc/XWikiDS</property> <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="statement_cache.size">2</property> <property name="hibernate.connection.SetBigStringTryClob">true</property> <property name="hibernate.jdbc.batch_size">0</property> <mapping resource="xwiki.oracle.hbm.xml"/> <mapping resource="feeds.oracle.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> c) settings in xwiki/WEB-INF/web.xml <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/XWikiDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> (using <ResourceLink name="jdbc/XWikiDS" global="jdbc/XWikiDS"
