You would have to use the error-page element in web.xml to specify the invocation of servlets in response to certain exceptions or HTTP status codes. web.xml Configuration: Consider, you have an ErrorHandler servlet which would be called whenever there is any defined exception or error. Following would be the entry created in web.xml.

Sometime back I wrote a post about Exception Handling in Java but when it comes to web application, we need more than normal exception handling in java.Servlet ExceptionIf you notice, doGet() and doPost() methods throw javax.servlet.ServletException and IOException, let's see what happens when we throw these exception from our application. I will write a simple servlet that will throw the ServletException. package com.journaldev.servlet.exception; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @WebServlet("/MyExceptionServlet") public class MyExceptionServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { throw new ServletException("GET method is not supported."); } } Now when we invoke this servlet through browser with GET method, we get response like below image.Since browser understand only HTML, when our application throw exception, servlet container processes the exception and generate a HTML response. This logic is specific to servlet container. I am using tomcat and getting this error page. If you will use some other servers like JBoss or Glassfish, you might get different error HTML response.The problem with this response is that it's of no value to user. Also it's showing our application classes and server details to user that makes no sense to user and it's not good from security point of view.Servlet ErrorI am sure you must have seen 404
