File notifications from Java on Windows

[brolund]

I have a weird problem (with a workaround hack, see below) at my client. Changes that the logging system on JBoss make to my log files are not caught by the fs.watch(dir) function, hence I get no input in node-logstash. I get the feeling this could be Java file writing that bypasses the Windows stuff that sends events via ReadDirectoryChangesW, but I have no backing for this (Google wasn't my friend today...).

So, I hacked a bit in directory_watcher.js and added an fs.watchFile(...) on each of the files in dir, and every 5 sec (configurable polling interval on watchFile) I get an event. Interestingly, this triggers the fs.watch(...) functionality, so I don't need to do anything in the fs.watchFile(...) handler function.

Has anyone seen anything like this? Any better workarounds?
