/**
* Factory bean that configures a TopLink SessionFactory and provides it as bean
* reference. This is the usual way to define a TopLink SessionFactory in a Spring
* application context, allowing to pass it to TopLink DAOs as bean reference.
*
* See the base class LocalSessionFactory for configuration details.
*
*
If your DAOs expect to receive a raw TopLink Session, consider defining a
* TransactionAwareSessionAdapter in front of this bean. This adapter will provide
* a TopLink Session rather than a SessionFactory as bean reference. Your DAOs can
* then, for example, access the currently active Session and UnitOfWork via
* Session.getActiveSession and Session.getActiveUnitOfWork,
* respectively. Note that you can still access the SessionFactory too, by defining
* a bean reference that points directly at the LocalSessionFactoryBean.
