No users available

Hi, I installed xwiki and there are no users installed and no option to create new users. The user's page is empty. The only way I found to work was to allow the superuser account but there is no other user and now way to add users. Any ideas? Juan Manuel Urraburu ProRM Uruguay

Delete access right
by Shawn Lauzon 08 Aug '07

08 Aug '07

Hi all, What is the delete access right supposed to do? It doesn't seem to do anything currently, at least in 1.0. In the albatross skin, if I enable delete rights in a space for a non-admin, the delete button does not appear for that user. Thanks ... shawn.

running xwiki on Ingres database
by advait 07 Aug '07

07 Aug '07

I am trying to run xwiki with Ingres, for this I have converted file xwiki-db-0.9.2.sql to ingres compatible format. And I ran this file on Ingres database. I have everything else in place: drivers, configuration in hibernate.cfg.xml etc... My app server is JBoss 4.0.5, so when I start xwiki I get: 17:54:49,830 FATAL [DBCPConnectionProvider] Could not create a DBCP pool java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:396) at com.xpn.xwiki.store.DBCPConnectionProvider.configure(DBCPConnectionProvider.java:110) at org.hibernate.connection.ConnectionProviderFactory.newConnectionProvider(ConnectionProviderFactory.java:80) at org.hibernate.cfg.SettingsFactory.createConnectionProvider(SettingsFactory.java:349) at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:58) at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:1509) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1054) at com.xpn.xwiki.store.XWikiHibernateBaseStore.initHibernate(XWikiHibernateBaseStore.java:125) so i removed connection.provider_class property from hibernate.cfg.xml. Afterwards when i tried running xwiki i got this exception and xwiki page is not coming: 18:11:49,447 ERROR [JDBCExceptionReporter] line 1, Table 'xwikidoc' owned by 'advait.trivedi' does not contain column 'xwd_default_template'. ....... I noticed that this column is not part of "create table" sql but somehow it is getting added to the table definition afterwards. Because i noticed this column using "describe xwikidoc" mysql command.

XWiki, Log4J and Tomcat Security Manager: success (almost)
by Fernando Lozano 31 Jul '07

31 Jul '07

Hi there, Working to solve my SecurityExceptions running on a shared hosting, I tried to create a similar environment on my local Tomcat. The problem is not solved, but what I got so far may be useful for some XWiki users. After running "server.bat -security" I started getting errors related to Log4J already described by other threads on the mailing list archive, which I solved this way: 1. Take the log4j.properties from WEB-INF/lib/xwiki.jar and put it as WEB-INF/classes. The Servlet API specs state that WEB-INF/classes comes in the web app classpath before jar files placed in WEB-INF/lib. 2. Changed so the log file gets an absolute path under the web app context: log4j.appender.file.File=C:/java/apache-tomcat-5.5.23/webapps/xwiki/xwiki.log 3. The default security config don't let an application write to its own files, so I had to add to Tomcat calatina.polity grant codeBase "file:${catalina.home}/webapps/xwiki/-" { permission java.io.FilePermission "c:/java/apache-tomcat-5.5.23/webapps/xwiki/-", "read,write,delete"; }; And them when I start XWiki I get the same error I get from my hosting provider, that is: javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: access denied (java.io.FilePermission \WEB-INF\xwiki.cfg read) Note that you could have used System Properties in the policy file, such as: grant codeBase "file:${catalina.home}/webapps/xwiki/-" { permission java.io.FilePermission "${catalina.home}/webapps/xwiki/-", "read,write,delete"; }; And you could have specified a file path completely outside the context tree, which would be better from a security standpoint. Then I though: Why not adding a permission to "/WEB-INF/xwiki.cfg" so the (buggy) XWiki configuration file access code works as it would without a Security Manager? The changes to catalina.policy become: grant codeBase "file:${catalina.home}/webapps/xwiki/-" { permission java.io.FilePermission "${catalina.home}/webapps/xwiki/-", "read,write,delete"; permission java.io.FilePermission "/WEB-INF/xwiki.cfg", "read"; }; And the result is: javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load store class com.xpn.xwiki.store.XWikiHibernateStore Wrapped Exception: access denied (java.io.FilePermission \WEB-INF\hibernate.cfg.xml read) Hey, XWiki reads the Hibernate configuration file the same way it reads it's own configuration file... I guess it shouldn't, but let's apply the same workaround: permission java.io.FilePermission "/WEB-INF/hibernate.cfg.xml", "read"; And then I get: com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: Could not create a DBCP pool com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:291) com.xpn.xwiki.XWiki.getXWiki(XWiki.java:383) com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:96) My DBCP Pool config should be ok because the same local XWiki instance runs fine without a security manager. Probably I need something else (that is, not a java.io.FilePermission) to reach the local MySQL database. Hum, who knows using an embebed HSQLDB would be a workaround.... Digging into Tomcat logs, I found: java.net.SocketException: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:3306 connect,resolve) at com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:151) at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:280) at com.mysql.jdbc.Connection.createNewIO(Connection.java:1765) at com.mysql.jdbc.Connection.<init>(Connection.java:430) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:268) Which leads to a new permission: permission java.net.SocketPermission "127.0.0.1:3306", "connect, resolve"; And now to a different exception: com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: net.sf.ehcache.CacheException: Cannot configure CacheManager: jar:file:/C:/java/apache-tomcat-5.5.23/webapps/xwiki/WEB-INF/lib/xwiki.jar!/ehcache.xml:12: Could not set attribute "path". com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:291) com.xpn.xwiki.XWiki.getXWiki(XWiki.java:383) com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:96) Another configuration file to migrate to WEB-INF/classes. Changed it so ehcache never uses disk: <ehcache>  <defaultCache maxElementsInMemory="10000" eternal="false" overflowToDisk="false" timeToIdleSeconds="120" timeToLiveSeconds="120"  diskPersistent="false" diskExpiryThreadIntervalSeconds="120" /> </ehcache> And I got stuck to a reflection error inside Struts: javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks) org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:535) Well, I know a number of Struts applications that run in shared hosting plans. There should be a way out of this. But as I was already messing with catalina.polocy, I added: permission java.lang.reflect.ReflectPermission "suppressAccessChecks"; And now finally XWiki starts fine. But when trying to create a new page: com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Main.Teste do SandBox Wrapped Exception: Error number 3211 in 3: Exception while updating archive Main.Teste do SandBox Wrapped Exception: access denied (java.util.PropertyPermission user.name read) And here we go, more messing with catalina.policy: permission java.util.PropertyPermission "user.name", "read"; No I can create new pages inside the Wiki, and add Comments and files to the page. Looks like I found all it takes to run XWiki inside a Security Manager. Here's the final form of my aditions to catalina.policy: grant codeBase "file:${catalina.home}/webapps/xwiki/-" { permission java.io.FilePermission "${catalina.home}/webapps/xwiki/-", "read,write,delete"; permission java.io.FilePermission "/WEB-INF/xwiki.cfg", "read"; permission java.io.FilePermission "/WEB-INF/hibernate.cfg.xml", "read"; permission java.net.SocketPermission "127.0.0.1:3306", "connect, resolve"; permission java.lang.reflect.ReflectPermission "suppressAccessChecks"; permission java.util.PropertyPermission "user.name", "read"; }; And dont' forget changes to lig4j.properties and ehcache.xml which had to be moved from WEB-INF/lib/xwiki.jar to WEB-INF/classes. The problem is, I'm almost sure my ISP will refuse to add [java.lang.reflect.ReflectPermission "suppressAccessChecks"]. Others should be fine. So I'd be very grateful if someone helps me making Struts not need this permission. []s, Fernando Lozano

Authentication using LDAP and user names with dots
by Eric ter Haar 31 Jul '07

31 Jul '07

I already tried to post this question earlier via the ObjectWeb Sympa interface, but did not see it back in the archive list, nor did I get a e-mail confirmation. So please excuse me if it is posted twice now. I am currently evaluating XWiki for deployment in my company. So far everything looks great, but I ran into a blocking issue. I have setup XWiki to authenticate with LDAP, which is a requirement for us. The user names provided by our LDAP server all have dots in them, like 'eric.ter.haar'. XWiki seems to have a problem with this. When login in for the first time it creates a new user name that is equal to the part after the last dot, e.g., 'haar'. And it creates a space with the other part, like 'eric.ter'. The next login fails but without any notice. Does anyone know how to get around this? Thanks, Eric

hej, does anyone know whether it is possible to import a snipsnap exported xml ? as far as i know both are based on the radeox engine and as snipsnap is no longer maintained, lots of people will have to look for a migration path - and xwiki looks really promising. greetings from vienna gerold

Access denied to xwiki.cfg
by Fernando Lozano 30 Jul '07

30 Jul '07

Hi there, After running XWiki fine in my local server, I'm trying to run it on my hosting provider. Acces to WebHome yelds the error: javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: access denied (java.io.FilePermission /WEB-INF/xwiki.cfg read) I tried changing web.xml to <env-entry> <env-entry-name>XWikiConfig</env-entry-name>  <env-entry-value>/virtual/lozano.eti.br/www/xwiki/WEB-INF/xwiki.cfg</env -entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> That is, I tried cofiguring the real phisical path to the xwiki.cfg file, But still get the same error. My ISP tells me Xwiki is trying to get /WEB-INF/xwiki.cfg as an absolute file system path, not as a context-relative path, and it looks like changing the <env-entry> has no effect. What should I do?
