Re: [xwiki-users] Could not initialize main XWiki context when installing version 2.1.1

I just installed a fresh install of xwiki 2.1.1 I had previously used v2.0 without any problems. I did the following to install 2.1.1 - Got a backup of the mysql database folder and the tomcat webapps/xwiki folder to backup the v2.0 - delete the database - Created the database as shown below mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | +--------------------+ 2 rows in set (0.13 sec) mysql> create database xwiki -> ; Query OK, 1 row affected (0.08 sec) mysql> grant all privileges on xwiki.* to xwiki(a)127.0.0.1 identified by 'xwiki' -> ; Query OK, 0 rows affected (0.34 sec) mysql> - I then updated the hibernate.cfg.xml file. All i did in this file is comment out the hsqldb configuration and uncommented the mysql configuration. Here is my hibernate.cfg.xml file --- <?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Please refer to the installation guide on http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installationfor configuring your database.
