Method Detail
beforeDelivery
public void beforeDelivery(Method method) throws ResourceException
ThisbeforeDeliveryimplementation starts a transaction, if necessary, and exposes the endpoint ClassLoader as current thread context ClassLoader.Note that the JCA 1.5 specification does not require a ResourceAdapter to call this method before invoking the concrete endpoint. If this method has not been called (check
hasBeforeDeliveryBeenCalled()), the concrete endpoint method should callbeforeDeliveryand its siblingafterDelivery()explicitly, as part of its own processing.- Specified by:
beforeDeliveryin interfaceMessageEndpoint- Throws:
ResourceException
getEndpointClassLoader
protected abstract ClassLoader getEndpointClassLoader()
Template method for exposing the endpoint's ClassLoader (typically the ClassLoader that the message listener class has been loaded with).- Returns:
- the endpoint ClassLoader (never
null)
hasBeforeDeliveryBeenCalled
protected final boolean hasBeforeDeliveryBeenCalled()
Return whether thebeforeDelivery(java.lang.reflect.Method)method of this endpoint has already been called.
onEndpointException
protected final void onEndpointException(Throwable ex)
Callback method for notifying the endpoint base class that the concrete endpoint invocation led to an exception.To be invoked by subclasses in case of the concrete endpoint throwing an exception.
- Parameters:
ex- the exception thrown from the concrete endpoint
afterDelivery
public void afterDelivery() throws ResourceException
ThisafterDeliveryimplementation resets the thread context ClassLoader and completes the transaction, if any.Note that the JCA 1.5 specification does not require a ResourceAdapter to call this method after invoking the concrete endpoint. See the explanation in
beforeDelivery(java.lang.reflect.Method)'s javadoc.- Specified by:

ResourceException
