Send 404 using request dispatcher JSP

I am implementing a custom 404 handler in JSP - AEM, CQ. The file lives in apps/sling/servlet/errorhandler/404.jsp

I am intercepting the request for Not Found and forwarding using RequestDispatcher class.

<%@taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling"%>
<sling:defineObjects />
<%
    // setting response code as 404
    response.setStatus(HttpServletResponse.SC_NOT_FOUND);
response.setStatus(404);
System.out.println(response.getStatus());
        try {
            RequestDispatcher rd = request.getRequestDispatcher("/error-page.html");

            rd.forward(request, response);


        } catch (Exception e) {
            RequestDispatcher rd = request.getRequestDispatcher("/error-page.html");
            rd.forward(request, response);

        }

%>

The above code gets the content of error-page.html keeping the URL same, but the response code sent back is not 404. It is 200 instead.

How can I return a 404?

Using #include rather than #forward will allow you to return a 404:

response.setStatus(HttpServletResponse.SC_NOT_FOUND);
RequestDispatcher dispatcher = request.getRequestDispatcher(path);
dispatcher.include(request,response);

I would suggest creating a Java Servlet rather than using JSP:

@SlingServlet(metatype = true, resourceTypes = {"/apps/sling/servlet/errorhandler"}, extensions = {"404"})
public class ErrorServlet extends SlingSafeMethodsServlet {

    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
        response.setStatus(HttpServletResponse.SC_NOT_FOUND);
        RequestDispatcher dispatcher = request.getRequestDispatcher("myPath");
        dispatcher.include(request,response);
    }
}

Are you checking for the status code in AEM directly or are you checking after Apache and Dispatcher?
