How does JSP handle run-time exceptions (JSP)

Question :How does JSP handle run-time exceptions? (JSP)
Answer :You 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" %>
the Throwable object describing the exception may be accessed within the
error page via the exception implicit object.
Note: You must always use a relative URL as the value for the errorPage
