Question

What is wrong with this configuration? I’m using Spring 3 and Hibernate 3.6 and trying to set up to use DAOs. I’m seeing two errors in hibernate.cfg.xml.

The first is on the session-factory tag-

 The content of element type "session-factory" must match 
"(property*,mapping*,(class-cache|collection-cache)*,event*,listener*)".

The second is on the – property name=”dataSource” – tag-

The content of element type "property" must match "null".

Answer 1

You mixed Hibernate and Spring configurations. They are completelly separate. You can’t use Spring beans inside Hibernate config.

This will need to go to your Spring config:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
   <ref bean="dataSource"/>
</property>    
  <!-- SQL dialect -->
  <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
  <!-- Disable the second-level cache  -->
  <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
  <!-- Echo all executed SQL to stdout -->
  <property name="show_sql">true</property>
  <property name="transaction.factory_class">
   org.hibernate.transaction.JDBCTransactionFactory
  </property>
  <property name="current_session_context_class">
  thread
  </property>
</bean>

I may be mistaken over small things since I usually use annotations configuration but you should go back to documentation.
