So I have done servlet error page like this: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try{ //Here is all code stuff }catch(Exception e){ request.getRequestDispatcher("/ErrorPage.jsp").forward(request, response); e1.printStackTrace(); } Is this the correct way, if I am wrong please correct me and if there is any better mechanism please tell me. java jsp servlets error-handling jstl share|improve this question edited Nov 11 '14 at 9:13 Roman C 34.4k133559 asked Nov 7 '14 at 12:13 Raghu 4492926 Duplicate of stackoverflow.com/q/7066192 Performing forward() as in your snippet and in the answer below is at least wrong.

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.

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.
