java.lang.Objectorg.springframework.ejb.support.AbstractEnterpriseBean
org.springframework.ejb.support.AbstractSessionBean
org.springframework.ejb.support.AbstractStatefulSessionBean
Convenient superclass for stateful session beans. SFSBs should extend this class, leaving them to implement the ejbActivate() and ejbPassivate() lifecycle methods to comply with the requirements of the EJB specification.
Note: Subclasses should invoke the loadBeanFactory() method in their custom ejbCreate and ejbActivate methods, and should invoke the unloadBeanFactory() method in their ejbPassivate method.
Note: The default BeanFactoryLocator used by this class's superclass (ContextJndiBeanFactoryLocator) is not serializable. Therefore, when using the default BeanFactoryLocator, or another variant which is not serializable, subclasses must call setBeanFactoryLocator(null) in ejbPassivate, with a corresponding call to setBeanFactoryLocator(xxx) in ejbActivate unless relying on the default locator.

protected void loadBeanFactory() throws BeansException

the BeanFactory is known to be serializable, this method
must also be called from ejbActivate(), to reload a context
removed via a call to unloadBeanFactory from ejbPassivate.

public void setBeanFactoryLocator(BeanFactoryLocator beanFactoryLocator)
Can be invoked before loadBeanFactory, for example in constructor or setSessionContext if you want to override the default locator.
Note that the BeanFactory is automatically loaded by the ejbCreate implementations of AbstractStatelessSessionBean and AbstractMessageDriverBean but needs to be explicitly loaded in custom AbstractStatefulSessionBean ejbCreate methods.

public void setBeanFactoryLocatorKey(java.lang.String factoryKey)
In case of the default BeanFactoryLocator implementation, ContextJndiBeanFactoryLocator, this is the JNDI path. The default value of this property is "java:comp/env/ejb/BeanFactoryPath".
Can be invoked before loadBeanFactory, for example in constructor or setSessionContext if you want to override the default locator key.

public void ejbRemove()
Don't override it (although it can't be made final): code your shutdown in onEjbRemove.
AbstractEnterpriseBean.onEjbRemove()
protected void onEjbRemove()
This implementation is empty, to be overridden in subclasses. The same restrictions apply to the work of this method as to an ejbRemove() method.
