Java: what information in error stack trace do we typically not wish to show users?

Question

I\'m new to java and I\'m not that familiar with the formatting rules used by an error stack trace when it is thrown and subsequently displayed to an end-user of my web appl

Answer 1

You should only show stack traces when your app is in debug mode. In production mode, you should show a generic error message (or implement an Exception.getUserFriendlyMessage())and log the error (provide a log id if possible).
