public abstract class AbstractJmsMessageDrivenBean
extends AbstractMessageDrivenBean
implements MessageListener

Convenient superclass for JMS MDBs. Requires subclasses to implement the JMS interface javax.jms.MessageListener.

Method Detail

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.

AbstractStatelessSessionBean.ejbCreate(), AbstractMessageDrivenBean.ejbCreate(), AbstractStatefulSessionBean.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.

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.
