HANDLING CUSTOM ERROR PAGES IN TOMCAT WITH SPRING MVC

web.xml

<error-page>
    <location>/error.jsp</location>
</error-page>

Create a file named 'error.jsp' under 'WEB-INF' with following contents. This jsp file will redirect to error404 action under error controller.

<!DOCTYPE html>
<%@taglib prefix="UiTabLib" uri="UiTabLib" %>
<html>
    <head>
        <title></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <meta http-equiv="REFRESH" content="0;url=<UiTabLib:contextPath/>error/error404.htm?<UiTabLib:logError 

request="${requestScope}"/>">
    </head>
    <body>
        &nbsp;
    </body>
</html>

ErrorController.java

package com.pkm.maven.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class ErrorController extends MultiActionController {
    public ModelAndView error404(HttpServletRequest request, HttpServletResponse response) throws Exception {
        response.setStatus( HttpServletResponse.SC_BAD_REQUEST  );
        String statusCode = request.getParameter("status_code");
        String exception = request.getParameter("exception");
        String requestUri = request.getParameter("request_uri");
        if (requestUri == null) {
            requestUri = "Unknown";
        }
  
        ModelAndView view = new ModelAndView("error/error404");
        view.addObject("statusCode", statusCode);
        view.addObject("exception", exception);
        view.addObject("requestUri", requestUri);
        
        return view; 
    }
}

Create a file named 'error404.jsp' under 'WEB-INF/jsp/error/' folder with following content:

<div>Request URI: ${requestUri}</div>
<div>Status Code: ${statusCode}</div>
<div>Exception: ${exception}</div>
