    Original file name as message property for File/FTP gateways

    Derek Adams Newbie

      I have some code that adds the originating filename as a property on messages coming from file or FTP gateways. In our business case, we needed to be able to take the original filename, modify it with a timestamp and use that as the filename on an outgoing FTP. Our solution was an action that executes a chain of strategies on the incoming filename, passing the end result to a NotifyFTP action. The config looks like this...

      The FileNameGeneratorAction uses the message property for originating filename set in the gateway by default (can be changed via action props) and writes the result to a well-known message prop name. The NotifyFTP action picks up the result value and uses that as the filename it writes.

      I figure that this may be helpful to other people with similar requirements, so I was wondering if I should check the code in. Alternatively, I can add a JIRA and attach the updates so people can take a look before it goes in the trunk.

      Thanks,
      Derek
