You can handle any exceptions that are thrown from the body of the implementation class and are not caught by using an error page that you specify using a page directive. Both the client request and the uncaught exception are forwarded to the error page.
To specify an error page for a JSP, set its errorPage attribute to the URL of the error page in a page directive:
<%@ page errorPage="ErrorPage.jsp" %>
The java.lang.Throwable exception is stored in the javax.ServletRequest instance for the client request using the putAttribute method, using the name javax.servlet.jsp.jspException.
