Guillaume Nodet updated SM-227:
-------------------------------

    Fix Version:     (was: 3.0)

>  I have 2 FilePollers that receives messages from 2 folders. The first poller sends to a XSLT Service Engine and a FTPWriter after.
> How can I assure that the message got no errors from 
> a) Receiving from FilePoller 
> b) Transforming using XSL 
> c) Sending to the FTP site ? 
> If an error occurs when transforming, the message could be mal-formed. How can an action be done on this ?
> If the FTP Site is down, how can a user be notified of that and retry sending the message later ?
> I think that 2 steps must be taken:
> 1) Exceptions must be categorized: Is it a communication exception or a message/exchange error ?
> 2) Provide a way to customize the behavior of such event of failure, like sending an email or writing to a diferent FTP site.
> The message must be redelivered also in case of a communication failure. Then:
> - How long should a message tried to be redelivered ?
> - How many tries it should take before sending an email (handling the communication failure event)
> - Should newer messages be delivered BEFORE pending messages ?
> - How can an exchange be redelivered ?
