Join them; it only takes a minute: Sign up Dynamic Error Page from Servlet Response Errors up vote 1 how to set error page in jsp down vote favorite I'm trying to use the HttpServletResponse function sendError(int,string) to deliver a status code and custom error message to a JSP so I can have a dynamic error page (rather than many specific error pages for each error code/Java exception). However, I can't seem to access the custom message, error type, and stack trace. I can access the URI and Error Code however. I'm sending the error like such: response.sendError(HttpServletResponse.SC_BAD_REQUEST,"Some_Message"); I'm trying to get the response in my like this:
Error: | ${pageContext.errorData.throwable.cause} |
URI: | ${pageContext.errorData.requestURI} | Error Message: | ${pageContext.errorData.throwable.message} |
Status code: | ${pageContext.errorData.statusCode} |
Stack trace: | ${trace} |

Recall from Chapter 7, how the page directive can specify a JSP page to be used when code in the JSP page throws an exception. The error page gets access to the exception through an implicit variable named exception, and can display a user-friendly message as well as log details about the problem. The way the error page is invoked and how the implicit variable gets its value can easily be mimicked by a servlet. Example 14.4 shows how to do this in the controller servlet used in previous examples in this chapter.Example 14-4. Invoking a JSP Error Page from a Servlet public void doPost(HttpServletRequest request, HttpServletResponse response) { ... try { action.perform(this, request, response); } catch (Throwable t) { request.setAttribute("javax.servlet.jsp.jspException", t); RequestDispatcher rd = getServletContext( ).getRequestDispatcher("/error.jsp"); rd.forward(request, response); } }The servlet calls the action’s perform( ) method within a try block. If any type of exception occurs while executing an action, the servlet catc
