Unexpected Error Logging

[Ronnie Phelps]

Can someone point me in the right direction on where I would want to begin creating an error log for my jsp pages. I don't have a problem throwing and logging expected errors in JSP when they occur...I need to somehow log error messages that are unexpected.

If you set up a JSP called for example "myError.jsp" with this directive
<%@ page isErrorPage="true" %>
and then use <%@ page errorPage="myError.jsp" %>
in other pages, then any runtime exceptions in a JSP will cause "myError.jsp" to be executed. In this page you can do the logging.
I would <jsp:forward page="LoggingServlet"/> to a Servlet and do the logging there since I prefer not to have too much Java code in a JSP.

I didn't know that this approach would apply to any runtime exception. Thanks Tony that was very helpful.
