## Class AbstractStatefulSessionBean

- java.lang.Object
- - org.springframework.ejb.support.AbstractEnterpriseBean
  - - org.springframework.ejb.support.AbstractSessionBean
    - - org.springframework.ejb.support.AbstractStatefulSessionBean

- All Implemented Interfaces:
    Serializable, EnterpriseBean, SessionBean, SmartSessionBean

  Deprecated.
  as of Spring 3.2, in favor of implementing EJBs in EJB 3 style

      @Deprecated
      public abstract class AbstractStatefulSessionBean
      extends AbstractSessionBean

  Convenient base class for EJB 2.x stateful session beans (SFSBs). 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.

    - #### loadBeanFactory

          protected void loadBeanFactory()
                                  throws BeansException

      Deprecated.
      Load a Spring BeanFactory namespace. Exposed for subclasses to load a BeanFactory in their `ejbCreate()` methods. Those callers would normally want to catch BeansException and rethrow it as `CreateException`. Unless 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 the `ejbPassivate()` implementation.
      Throws:
        `BeansException`

        `AbstractStatelessSessionBean.ejbCreate()`

    - #### unloadBeanFactory

          protected void unloadBeanFactory()
                                    throws FatalBeanException

      Deprecated.
      Unload the Spring BeanFactory instance. The default `ejbRemove()` method invokes this method, but subclasses which override `ejbRemove()` must invoke this method themselves.

      Unless the BeanFactory is known to be serializable, this method must also be called from `ejbPassivate()`, with a corresponding call to `loadBeanFactory()` from `ejbActivate()`.

      Throws:
        `FatalBeanException`
