Method Detail

createEndpoint

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

boolean isDeliveryTransacted(Method method)
                             throws 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:: NoSuchMethodException - indicates that the specified method does not exist on the target endpoint.
