Hello, Could you please point me to possible root of the following problems: 1) Null pointer exception in formatDate() method during Main.RecentChanges page rendering (it looks like $rcDt variable is null for one of the records, this is for scripts from xwiki-enterprise-wiki-2.2.2.xar). Full stack trace attached in http://n2.nabble.com/file/n4783806/RecentChangesStackTrace.txt RecentChangesStackTrace.txt 2) A weird look&feel of the ManageGroups, ManageUsers and ManageRights ( http://n2.nabble.com/file/n4783806/ManageRightsBroken.JPG ManageRightsBroken.JPG , http://n2.nabble.com/file/n4783806/ManageGroupsBroken.JPG ManageGroupsBroken.JPG and http://n2.nabble.com/file/n4783806/ManageUsersBroken.JPG ManageUsersBroken.JPG page-captures correspondingly) Re-importing xwiki-enterprise-wiki-2.2.2.xar did not help. From the recent modifications made I can point out only the following * Set up 80(publicly available)->8080(where the XWiki is installed) port forwarding at firewall level * Restricted guest users from accessing the site and from registering Notes about environment * XWiki Enterprise Core/UI 2.2.2 * Most of users with LDAP Authentication + Several users with non-LDAP authentication * CentOS release 5.4 (Final) * Following errors on startup Starting tomcat5: /usr/bin/rebuild-jar-repository: error: Could not find jdbc-stdext Java extension for this JVM /usr/bin/rebuild-jar-repository: error: Could not find jndi Java extension for this JVM /usr/bin/rebuild-jar-repository: error: Some detected jars were not found for this jvm /usr/bin/rebuild-jar-repository: error: Could not find jaas Java extension for this JVM /usr/bin/rebuild-jar-repository: error: Some detected jars were not found for this jvm * XWiki cannot access file xwiki.log because of permission denied Regards, Roman -- View this message in context: http://n2.nabble.com/Null-pointer-exception-in-formatDate-on-rendering-Main-...
