Method Detail

createEndpoint

public MessageEndpoint createEndpoint(XAResource xaResource)
                               throws UnavailableException

This is used to create a message endpoint. The message endpoint is expected to implement the correct message listener type.

Parameters:

xaResource - an optional XAResource instance used to get transaction notifications when the message delivery is transacted.

Returns:

a message endpoint instance.

Throws:

UnavailableException - indicates a transient failure in creating a message endpoint. Subsequent attempts to create a message endpoint might succeed.

isDeliveryTransacted

public boolean isDeliveryTransacted(java.lang.reflect.Method method)
                             throws java.lang.NoSuchMethodException

This is used to find out whether message deliveries to a target method on a message listener interface that is implemented by a message endpoint will be transacted or not. The message endpoint may indicate its transacted delivery preferences (at a per method level) through its deployment descriptor. The message delivery preferences must not change during the lifetime of a message endpoint.

Parameters:

method - description of a target method. This information about the intended target method allows an application server to find out whether the target method call will be transacted or not.

Returns:

true, if message endpoint requires transacted message delivery.

Throws:

java.lang.NoSuchMethodException - indicates that the specified method does not exist on the target endpoint.
