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.

Method Detail

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
