Constant Field Values

AbstractStatefulSessionBean

public AbstractStatefulSessionBean()

loadBeanFactory

protected void loadBeanFactory()
                        throws BeansException

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

See Also:

AbstractStatelessSessionBean.ejbCreate()

unloadBeanFactory

protected void unloadBeanFactory()
                          throws FatalBeanException

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

setSessionContext

public void setSessionContext(SessionContext sessionContext)

Set the session context.

If overriding this method, be sure to invoke this form of it first.

Specified by:

setSessionContext in interface SessionBean

Parameters:

sessionContext - the SessionContext for this EJB

getSessionContext

public final SessionContext getSessionContext()

Convenience method for subclasses. Return the EJB context saved on initialization.

Specified by:

getSessionContext in interface SmartSessionBean

Returns:

the SessionContext saved on initialization by this class's implementation of the setSessionContext method

setBeanFactoryLocator

public void setBeanFactoryLocator(BeanFactoryLocator beanFactoryLocator)

Set the BeanFactoryLocator to use for this EJB. Default is a ContextJndiBeanFactoryLocator.

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.

See Also:

AbstractStatelessSessionBean.ejbCreate(), AbstractMessageDrivenBean.ejbCreate(), loadBeanFactory(), ContextJndiBeanFactoryLocator

setBeanFactoryLocatorKey

public void setBeanFactoryLocatorKey(String factoryKey)

Set the bean factory locator key.

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.

See Also:

BEAN_FACTORY_PATH_ENVIRONMENT_KEY

getBeanFactory

protected BeanFactory getBeanFactory()

May be called after ejbCreate().

Returns:

the bean factory

ejbRemove

public void ejbRemove()

EJB lifecycle method, implemented to invoke onEjbRemote and unload the BeanFactory afterwards.

Don't override it (although it can't be made final): code your shutdown in onEjbRemove.

See Also:

onEjbRemove()

onEjbRemove

protected void onEjbRemove()

Subclasses must implement this method to do any initialization they would otherwise have done in an ejbRemove() method. The BeanFactory will be unloaded afterwards.

This implementation is empty, to be overridden in subclasses. The same restrictions apply to the work of this method as to an ejbRemove() method.
