Hi everyone, I'm new on xwiki, never heard of it before but here in the company they want to give it a try. I've been searching a lot now about this error and I think mine is quite particular from what I read and my conf. I followed this steps in order to complete the xwiki installation. 1) Copy the xwiki.war into the webapps folder,inside a new folder called xwiki 2) Copy the mysql driver (mysql-connector-java-5.1.9.jar) into $TOMCAT_HOME/webapps/xwiki/WEB_INF/lib 3) Edit the hibernate.cfg.xml file to use the mysql database 4) Then opened Mozilla at http://myaddres:9191/xwiki/ I get the following error pointing to hibernate.cfg.xml from what I see javax.servlet.ServletException: 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 [name = [XWikiPreferences], type = [DOCUMENT], parent = [name = [XWiki], type = [SPACE], parent = [name = [xwiki], type = [WIKI], parent = [null]]]] Wrapped Exception: Could not create a DBCP pool.

The server has XAMMP installed (PHP, MySQL, Apache) configured with another application, so I assume that I dont need to install MySQL since it's working now across XAMMP, and the process mysqld is running (we are using Linux CentOS, based on Red Hat), so we are not sure what's next about this problem. Any help would be appreciated, thanks in advance. -- View this message in context: http://xwiki.475771.n2.nabble.com/Another-installation-problem-tp7580408.htm...
