Session objects, by definition, are not persistent. They may, however, contain information that needs to be
made persistent. As with bean-managed entity objects, session objects can implement persistence operations directly in the methods in the enterprise bean. Session objects also often maintain a cache of database information that must be synchronized with the database when transactions are started, committed, or aborted.

JDO, or SQLJ) directly in the session bean class methods. See:
