22. jsf exception    coderanch.com

Hmmmm. I'm not sure it's OK to list thrown exceptions. It seems unlikely, since the JSF framework isn't written to expect them.

Technically-savvy people can obtain all sorts of information about what's inside the webapp, and perhaps then exploit it for evil purposes. You're better off outputting the stacktrace to a logfile. Most loggers, in ...
