>                 URL:
>             Project: CXF
>          Issue Type: Bug
>          Components: JMS, Transports
>    Affects Versions: 3.0.5
>            Reporter: Waldemar Szostak
>            Assignee: Christian Schneider
>            Priority: Critical
> In one-way communication (fire & forget), if:
> * there is an exception thrown by the user code, or 
> * the message is not a valid SOAP message, or 
> * the message's SOAP body is not a valid XML, 
> the exception is not handled, but instead propagated down to the message listener causing
the session to be rolled back (and thus the message to be un-acknowledged), which sort of
puts the message back in the topic and makes it eligible for a re-delivery.
> Of course, the message itself is not modified, so we have a circle..
> Even though this is one-way communication, I would either expect a fault message to be
generated, or the exception to be logged as error and have the message acknowledged ('removed
from the topic'). The latter scenario at least for validation or unmarshalling exception -
the exception will always be generated then (unlike the user code exceptions which may be
due to temporary problems).
> In my project, I need transactions in my fire&forget communication to ensure the
message will be processed, despite any temporary problems, eg, with the database (=exceptions
from my code). However, in situations when a client sends an invalid message to my service,
I definitely do not want this message to block my service by being constantly re-delivered.
> Especially, please note that currently I have no control via my code or CXF  configuration
to have such invalid XML messages simply disregarded. Either I need to turn off transactions
(which I do not want to do because of my business exceptions which should cause the message
to be re-delivered), or override the is-one-way property (see also JMSDestination.processExceptions):
> {code}message.getExchange().setOneWay(false);{code}
