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 34.3k133559 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 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. NullPointerException)

either inside the page or outside the page (such as in a called JavaBean). This section describes the JSP error processing mechanism and provides a simple example. Using JSP Error Pages Any runtime error encountered during execution of a JSP page is handled using the standard Java exception mechanism in one of two ways: You can catch and handle exceptions in a Java scriptlet within the JSP page itself, using standard Java exception-handling code. Exceptions you do not catch in the JSP page will result in forwarding of the request and uncaught exception to an error page. This is the preferred way to handle JSP errors. You can specify the URL of an error page by setting the errorPage parameter in a page directive in the originating JSP page. (For an overview of JSP directives, including the page directive, see "Directives". ) In a servlet 2.2 environment, you can also specify a default error page in the web.xml deployment descriptor with instructions such as the following:
