How does JSP Handle Runtime Exceptions ?

We can use the errorPage attribute of the page directive to have uncaught run-time exceptions automatically forwarded to an error processing page. For example:
            <%@ page errorPage=\"error.jsp\" %>
redirects the browser to the JSP page error.jsp if an uncaught exception is encountered during request

processing. Within error.jsp, if you indicate that it is an error-processing page, via the directive:
<%@ page isErrorPage=\"true\" %>.
