How to view custom 404 page

Hi, can anyone point me how to view my custom 404 page. I searched and tried implementing ExceptionMapper<RuntimeException> but this did not work. I’m using 0.8.1 version

Thanks a lot. Works for me.

1. Add to XYZconfig.yml

server:
  registerDefaultExceptionMappers: false

1. Add to XYZApplication.java

    @Override
    public void run(CertConfiguration configuration, Environment environment) {
    	
        // init Error pages
    	 final ErrorPageErrorHandler epeh = new ErrorPageErrorHandler();
         // 400 - Bad Request, leave alone
         epeh.addErrorPage(401, "/error/general-error");
         epeh.addErrorPage(402, "/error/general-error");
         epeh.addErrorPage(403, "/error/403");
         epeh.addErrorPage(404, "/error/404");
         epeh.addErrorPage(405, 499, "/error/general-error");
         epeh.addErrorPage(500, 599, "/error/general-error");
         environment.getApplicationContext().setErrorHandler(epeh);
         environment.getAdminContext().setErrorHandler(epeh);
         
         ErrorResource  errorResource = new ErrorResource();
         environment.jersey().register(errorResource);

1. Add to ErrorResource.java

@Path("/error")
public class ErrorResource {

    public ErrorResource () {
    }

    @Path("404")
    @GET
    @Timed
    @Produces(MediaType.TEXT_HTML)
    public Response error(){
        return Response.status(404).entity(new ErrorView()).build();
    }

Works with assets and API. So maybe this issue can be closed?

Have you tried to set up your API on a different path, so JsonProcessingExceptionMapper doesn’t kick in? It can be done with the rootPath parameter in the YML config. Another option is to try to disable default exception mappers by setting the registerDefaultExceptionMappers parameter to false.
