I'm developing a program using Java that grabs files coming into an FTP server and moves them to another location on the internal network. I'm doing that fine - however, it appears sometimes (around 30% of the time) that the automated Java program I created is moving the files before it is complete (i.e. before the upload to the FTP for that file is done - the file size isn't complete apparently) and the resulting file (when opened after moving the file) is useless since it's incomplete and missing data. Anyone deal with this kind of problem or issue? How would you suggest I resolve this? Thanks.
