Copy the code below and run it in your favorite SQL editor. Please note that I have not rigorously tested this code, but it has successfully transferred files in both directions in the limited tests that I have performed. If you modify the code, I respectfully request that you leave intact the authorship and note comments at the beginning of the package. Suggestions on improving the code are welcome, and I can provide limited support via email for what I've written, but I would encourage anyone who uses the code to modify/fix it according to their needs.

The source code is hopefully documented well enough for you to tell what's going on and how to use the functions.

This FTP support is very basic, but leveraging the convenience APIs of. Surprisingly, there's already basic support for FTP in some JDK flavors in the form of, we shouldn't use this class directly and it's instead possible to use the JDK's class as an abstraction. It's recommended to always use the latest version. That's why we'll use MockFtpServer instead, a Fake/Stub FTP server written in Java, that provides an extensive API for easy use in JUnit tests: However especially when used in passive mode, an FTP server isn't the easiest application to run transparently inside a container if we want to make use of dynamic port mappings (which is often necessary for tests being able to be run on a shared CI server). Nowadays, we'd normally use Docker to spin up those systems for our integration tests. When using libraries, that are used to interact with external systems, it's often a good idea to write some additional integration tests, in order to make sure, we're using the library correctly.
