are you handling exceptions in your web applications? Does your team have a strategy or do you just deal with failures as they come up? If you're like most development teams, you just deal. Whenever something https://blog.stackhunter.com/2014/01/28/5-ways-to-handle-http-server-500-errors/ breaks, it's an emergency. Customer runs into a problem, you get called in. You dig http://gis.stackexchange.com/questions/186827/otp-server-internal-error through the logs to quickly find the culprit and you look like a hero. That's one scenario. Another scenario is that you don't find the problem so quickly. You are, after all, sifting through hundreds or thousands of users, sessions, threads, files, and servers.

One thing not to do on this page is to include an error code or incident number. Don't turn your customers into your monitoring system. They shouldn't have to call or email you with an error number. It's your site. You know who they are, you know what they were doing, and you know they had a problem. A custom error page won't make your site any more robust or save you time debugging, but it will make you look professional. 2. Log the Web Request The first big time saver is to log all request data with exceptions. This means whatever you can get your hands on from the HttpServletRequest (URL, headers, etc.). Stack traces are great at telling you where your code stopped working, but they suck at telling you why. For that you need the surrounding context.
