Hi,
I have the following scenario to be executed with proper exception handling. Can someone please help me out in coming up with a framework for this?

Scenario:
SOAPInput -->Compute --> SOAPReply --> Compute --> FileOutput --> Compute --> SOAPRequest

In this scenario, i first receive a WSRequest and acknowledge the receipt using SOAPReply. Then i create an output structure and place the file on a given FTP Location and once the file is successfully placed, i call a webservice to send the details of the file that was placed.

In this scenario, i have the following issues:
1. If FTP server is down, how do i block the fileoutput node to keep retrying until the FTP server comes up and file is placed successfully.
2. How do i place a sequence on the input messages so that unless (n-1)th message is processed, nth should not be picked from a local queue.
3. Any pointers on standard exception handling framework in message broker for webservices
4. Is it possible to use filenodes over VPN connection (FTP site is available over a VPN connection).
