So I have done like this: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException web.xml error-page not working { 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. 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 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. Using Exception Object: The exception object is an instance of a subclass of Throwable (e.g., java.lang. NullPointerExcep

Same explanation is also applicable for JSP pages also and that's why Java EE provides a clear approach for exception handling in error page 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, then we can access exception jsp implicit object in redirect to error 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-ASCII" pageEncoding="US-ASCII"%>
