[mule-user] Getting Last Modified Time From File

[Corey Mosher]

I'm working with my first mule flow and want to watch a directory for files and move them to another directory naming the file with the last modified timestamp appended to the output filename. Is there a way to get that information from an input file endpoint?

Hi,

There's no way to get the last modified time from a file but if your polling frequency is not very high maybe you can use #[function:datestamp] and append that to the output file as an approximation. Here [1] you can find an example about how to use that function.

HTH, Pablo.

I think if you change message adapter on the file connector to FileMessageAdapter (or whatever the actual name is now), and get a java.io.File object instead of a bye array, then lastModified value can be retrieved.

Another solution is, if you are suing streaming, you will have a ReceiverFileInputStream as payload. That class has a getCurrentFile() method which returns a java.io.File. You can get the last modified date from there.

It doesn't seem to be your case but if you use a working directory then you will be getting a wrong last modified date since that File object will represent the file moved to the working directory instead of the original file.

Thanks for the suggestions. I decided that I don't necessarily need the last modified time as long as my inbound file endpoint is using the OlderFirstComparator. I really just need to maintain the order the files arrived so I think this will do it combined with appending the current timestamp to the end of the filename once I move it.

Thanks

That's configuring a service override to use the
org.mule.transport.file.FileMuleMessageFactory. And make sure that
streaming=false on the endpoint.
