Same explanation is also applicable for JSP pages also and that's why Java EE provides a how to clear approach for exception handling in JSP using JSP error pages.To handle exceptions thrown by the JSP page, all we need is an error page and define the error page in JSP using jsp page directive.JSP Error PageTo create a JSP error page, we need to set page directive attribute isErrorPage value to true, how to display then we can access exception jsp implicit object in the JSP and use it to send customized error message to the client.JSP Error Page ConfigurationWe need to set page directive errorPage attribute to define the JSP that will handle any exception thrown by the JSP service method. When JSP Error page is translated to servlet code, it extends org.apache.jasper.runtime.HttpJspBase in Tomcat.Error Page Deployment Descriptor ConfigurationMost of the times, we have a common error page that we want to use for all the JSPs, so rather than configuring it in all the JSPs individually, we can define error page in web.xml with error-page element. We can configure JSP error page to handle other error codes like 404 also.Let's see how all these fit together in a web application.We will create a simple web application JSPExceptionHandling whose project structure will look like below image. The entry point of the application is index.jsp whose code is given below. <%@ page language="java" contentType="text/html; charset=US
