RE: "One way to tell is by registering a load-on-startup servlet and logging from its init method."
Is there any sort of unique identifier for the application instance that we can include in the log message? I'd like to be able to monitor how many instances of my application are running. I don't care what the identifier is and wouldn't try to use it for any other purpose. The only thing I can find that might work is the "user.dir" system property, which seems to vary based on application instance.
