This is pretty much what I've done in the past. I have a try..catch loop in my
controller servlet that catches any exceptions thrown by my action classes. (Of
course, I consider such things to be bugs, so that logfile gets attention).
One thing to consider using is the Servlet 2.2 mechanism for declaring <error-page>
directives in the "web.xml" file. You can direct particular types of errors to
particular JSP pages, which can then combine the logging action (in a scriptlet or
custom tag) with the display-to-the-user action. This way, you catch and log
exceptions in your JSP pages as well (perhaps from code in a scriptlet or custom
tag).
