Class Overview
Inner class for actual endpoint implementations, based on template method to allow for any kind of concrete endpoint implementation.

Public Methods
public void afterDelivery ()
This afterDelivery implementation 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(Method)'s javadoc.
Throws
| ResourceException |
|---|
public void beforeDelivery (Method method)
This beforeDelivery implementation 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 call beforeDelivery and its
sibling afterDelivery() explicitly, as part of its own processing.
Throws
| ResourceException |
|---|
public void release ()
Protected Methods
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)
protected final boolean hasBeforeDeliveryBeenCalled ()
Return whether the beforeDelivery(Method) method of this endpoint
has already been called.
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 |
