Agreed. I used this exact approach of moving from a stage directory to an incoming directory in a recent J2EE implementation. (As long as the directories are on the same disk partition.) However, in the case of a file being "pushed" to another system such as via FTP, something must monitor the file and know when it has been completely transferred before performing the move or errors can result. I guess my overall statement is be sure to consider the transfer latency SOMEWHERE in your architecture. 🙂
