These messages display fine, as long as you use the default ugly Tomcat error pages. However, if you create a custom error page, how do you get that message? I've tried exception.getMessage() or pageContext.getErrorData() but no avail. I've been searching for this for like hours and nobody seems to even wonder about the same thing! :S I forgot to mention I've only tried it with 404s so far, since that's what I need most... The exception is null for some reason, so trying anything on it throws a NullPointerException. The error page is a 404 error page, set via web.xml (since I want it to be displayed for EVERY single 404 error) and for anyone wondering, yes it has the isErrorPage directive set to true... jsp tomcat custom-error-pages share|improve this question edited Jun 15 '09 at 14:51 asked Jun 15 '09 at 9:46 Lea Verou 13.8k63142 Does your custom 404 page never work? How do you check if it works? Have you check if the below by me mentioned request attributes exist? Last resort try this tutorial playground.greyscale.se/wiki/en/Custom_404_page_in_Tomcat –jitter Jun 15 '09 at 15:48 No it works fine. I just don't know how to get the message, if set via response.sendError(). –Lea Verou Jun 15 '09 at 16:27 response.sendError() will send error to your clients browser. It will not go to your error page after that unless you will do it yourself I think. –Georgy Bolyuba Jun 15 '09 at 22:10 Nope, it displays the custom error page just fine, as long as you properly set it via web.xml :) The only thing is that I don't know how to get the error message, if set. –Lea Verou Jun 16 '09 at 0:17 @LeaVerou, did you ever find a solution to this? –craig Feb 20 '12 at 21:13 | s

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.

Sometime back I wrote a post about Exception Handling in Java but when it https://answers.atlassian.com/questions/14205148/javax.servlet.error.statuscode-500 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 error when you are trying to hit a URL that doesn't exists. Let's see how our servlet container responds to 404 error. If we send request for an invalid URL, we get response HTML like below image.Again it's a generic HTML generated by server on our application behalf and hold littl
