Actually, it's kind of interesting to find 2 guys discussing why they will break your code :-)
Ok, so in ESB 4.5, it was possible to instantiate FtpImp and SecureFtpImpl from a ConfigTree, so you could pass in the local dir, and it did work.
We use this to sort/separate the log (copies) of all our outgoing messages by use case, date, etc.
Now, you made the FtpImpl(ConfigTree) private, and removed the SecureFtpImpl(ConfigTree) altogether.
Now the local dir issue really doesn't make any sense any more, as you wrongly suspected two and a half years earlier.
So now I have to go to venus and back, to create a FtpEPR from my ConfigTree, so that you can create a ConfigTree from my FtpEPR again, losing some information in the process. :-(
That's something that doesn't make sense...
Cheers, Tom.
