I am trying to get xWiki up and running on CentOS9 with TomCat and MySQL DB.

When I try to go to xwiki, I get the following error message.

XWiki initialization failed!

cvc-complex-type.2.3: Element 'session-factory' cannot have character [children], because the type's content type is element-only.

This looks like an XML parsing error. Can you post you Hibernate config file?

#4

Using MySQL, so I commented out the default db.

         2) Uncomment the properties below for your specific DB (and comment the default

    <!-- Tell Hibernate to use XWiki's custom DBCP Connection Provider so that the DBCP pool is used -->
    <property name="hibernate.connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property>

    <!--
      Keep the old behavior. The new version of hibernate tries to delete and recreate unique
      constraints when updating the database schema. The problem is that an exception is thrown
      when the constraint to be deleted does not exists, which is the case with a new XWiki
      instance.
      See https://hibernate.atlassian.net/browse/HHH-8162
    -->
    <property name="hibernate.schema_update.unique_constraint_strategy">skip</property>

    <!-- Setting "hibernate.dbcp.poolPreparedStatements" to true and "hibernate.dbcp.maxOpenPreparedStatements" will
         tell DBCP to cache Prepared Statements (it's off by default). Note that for backward compatibility the
         "hibernate.dbcp.ps.maxActive" is also supported and when set it'll set "hibernate.dbcp.poolPreparedStatements"
         to true and "hibernate.dbcp.maxOpenPreparedStatements" to value of "hibernate.dbcp.ps.maxActive".

         Note 1: When using HSQLDB for example, it's important to NOT cache prepared statements because HSQLDB
         Prepared Statements (PS) contain the schema on which they were initially created and thus when switching
         schema if the same PS is reused it'll execute on the wrong schema! Since HSQLDB does internally cache
         prepared statement there's no performance loss by not caching Prepared Statements at the DBCP level.
         See https://jira.xwiki.org/browse/XWIKI-1740.
         Thus we recommend not turning on this configuration for HSQLDB unless you know what you're doing :)

         Note 2: The same applies to PostGreSQL.
