How to make FileAlterationObserver to observe a remote directory?
This can accept a String path or a Java File. Both the cases it will look for the directory in local context. I have a directory in remote server file system.
It would be also helpful if anyone tell me how to create a new File object referring to the file in the remote directory.
Example:
File file = new File("remote directory path");
回答1:
You cannot.
- The
Fileobject cannot refer to an SFTP file. - There's no way to have the SFTP server notify you on changes in a remote file/directory (the protocol itself does not have a mechanism for that).
All you can do is to use JSch (other other) SFTP interface to check for changes in regular intervals yourself.
