how to create a JSP error page to handle exceptions. Tutorial created using: Windows XP || JDK 1.5.0_09 || Eclipse Web Tools Platform 2.0 (Eclipse 3.3.0) || Tomcat 5.5.20 Page: 1 2> jsp iserrorpage When an exception is thrown in your web application and it is not caught, you will typically see the result featuring the exception displayed in your browser window, as shown here: Rather than displaying the above default page when an exception occurs, you can redirect the user to a custom-written error page for a particular type of exception. You can do this via the error-page element web.xml error-page not working in web.xmlW, in which you can specify an exception-type and the location of the resource where a user should be sent if an error occurs. In this example, I specified the exception-type as java.lang.Throwable so that all exceptions would be sent to the error.jsp page.

So I have done 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 http://stackoverflow.com/questions/26801038/how-to-redirect-to-error-page-when-exception-occurs-from-servlet 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 34.2k133559 asked Nov 7 '14 at 12:13 Raghu 4491926 Duplicate of stackoverflow.com/q/7066192 Performing forward() as in your snippet and in the answer below is at least wrong. If you really want to do it programmatically, you should be using sendError(), not forward(). –BalusC Jul 1 at 7:25 add a comment| 3 Answers 3 active oldest votes up vote 1 down vote accepted Only way to handle it in a generic way is to use web.xml like below:

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.

You can have following type of errors in your JSP code: Checked exceptions: Achecked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation. Runtime exceptions: A runtime exception is an exception that occurs that probably could have been avoided by the programmer. As opposed to checked exceptions, runtime exceptions are ignored at the time of compliation. Errors: These are not exceptions at all, but problems that arise beyond the control of the user or the programmer. Errors are typically ignored in your code because you can rarely do anything about an error. For example, if a stack overflow occurs, an error will arise. They are also ignored at the time of compilation. This tutorial will give you few simple and elegant ways to handle run time exception/error occuring in your JSP code.
