Java file locking on a network

Question

This is perhaps similar to previous posts, but I want to be specific about the use of locking on a network, rather than locally. I want to write a file to a shared location,

Answer 1

Rather than implementing a locking strategy which will, in all likelihood, rely on readers to adhere to your convention but will not force them to, perhaps you can write the file out to a hidden or obscurely named file where it will be effectively invisible to readers. When the write operation is complete, rename the file to the expected public name.

The downside is that hiding and/or renaming without additional IO may require you to use native OS commands, but the procedure to do so should be fairly simple and deterministic.
