10.3.2. Using a Seam-managed Hibernate session
Seam-managed Hibernate sessions work in a similar fashion. In
components.xml:
<persistence:hibernate-session-factory name="hibernateSessionFactory"/>
<persistence:managed-hibernate-session name="bookingDatabase"
auto-create="true"
session-factory-jndi-name="java:/bookingSessionFactory"/>
Here,
java:/bookingSessionFactory is the name of the session factory specified in hibernate.cfg.xml.
<session-factory name="java:/bookingSessionFactory">
<property name="transaction.flush_before_completion">true</property>
<property name="connection.release_mode">after_statement</property>
<property name="transaction.manager_lookup_class">
org.hibernate.transaction.JBossTransactionManagerLookup
</property>
<property name="transaction.factory_class">
org.hibernate.transaction.JTATransactionFactory
</property>
<property name="connection.datasource">
java:/bookingDatasource
</property>
...
</session-factory>
Note
Seam does not synchronize the session with the database, so always enable
hibernate.transaction.flush_before_completion to ensure that the session is automatically synchronized before the JTA transaction commits.
We can now inject a managed Hibernate
Session into our JavaBean components with the following code:
@In Session bookingDatabase;
