Hi all,

when I try to go to http://localhost:8080/xwiki/bin/view/Main/, Tomcat throws an exception:

com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load class com.xpn.xwiki.store.migration.hibernate.XWikiHibernateMigrationManager from param xwiki.store.migration.manager.class Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not execute query

Looking at the Tomcat logs, I find 2 errors in Catalina.out:

1)

2009-06-07 10:28:04,363 [http://localhost:8080/xwiki/bin/view/Main/] [http-8080-1] ERROR store.XWikiHibernateBaseStore - Failed updating schema while executing query [create table feeds_aggregatorgroup (agg_id integer not null, agg_name text, primary key (agg_id))] java.sql.SQLException: Can't create table 'feeds_aggregatorgroup' (errno: 13)

This looks like a database rights issue. Please make sure the database user has the right to modify the database, including creating and altering tables. If you don't want to give these rights for long, you can just temporarily grant them (or use a user with these rights) for the first time XWiki starts.

This might be a filesystem rights issue, make sure the user running the container has write access to the folder containing the database. -- Sergiu Dumitriu http://purl.org/net/sergiu/
