I have a flow (name - FILE READER FLOW) that will read a file from a local directory and then in addition of archiving the file it will also create a meta data file in the archive directory. The flow then send a message to a queue (ENTRY.IN).

Another flow (ENTRY FLOW) will pick the message from ENTRY.IN queue and then move the archived file and the meta data file to some remote location.

The problem here is that sometimes ENTRY FLOW processes the message, that FILE READER FLOW has sent, before the FILE READER FLOW could archive the file to the archive directory, which results in "file not found error"

As a solution i can put delay in my ENTRY FLOW but has anyone tackle this problem and can suggested some readymade solution.

FILE READER FLOW looks like this:

FileInputNode -> Java Compute Node -> MQOutput Node

The JCN node will create the meta data file and the message for the ENTRY FLOW.
