Re: [jetty-users] Either OR but not Both.
I have the  jsp  +  jaxrs jersey  2.33 using  jetty 9.

https://lit-taiga-52898.herokuapp.com/


If you guys decide to have a working example using jetty 11 and  jersey 3.0.1 
on github  please send me a link.

I think there are quite a  few bugs need fixing for that to happen.

Even with jetty 9 there were compatibility issues amongst  jetty 9 variations.

Thank you I also agree that is the correct jetty  reponse.

I am using embedded  jetty 11.
Using webAppContext for configuration.
we also have agreed that 
 " in jetty 11 there is indeed no ClassList, so that part is "broken".  ".

What  other method of configuration I  have available  for  adding  features as and when I need them  
to the embedded jetty 11  org.eclipse.jetty.server.Server object  apart from using ServletContextHandler   ?

Please send me  link showing the instructions.

Som,

Without a web.xml, the Jersey servlet is not setup to handle requests.   
Without Jersey, there is nothing in Jetty to map any request to MyResource.

Unless there is something annotated or in a discovered webfragment, then Jetty has no handler for that request and 404 is the correct response.

regards

<welcome-file-list> is only used when Jetty is in charge of serving static content.
Or said another way, when there is a request for a resource that doesn't match a url-pattern that the webapp has specified, then the servlet spec Default Servlet kicks in and determines static content, welcome-files, etc ...

You have jersey setup with <url-pattern>/*</url-pattern>, which means Jersey is responsible for 100% of content served.
Jetty is not involved in much with that configuration.

I don't understand this kind of configuration, Jersey usage should be focused, only on REST api resources, not 100% of content, including static and default servlet.
I would recommend that you specify jersey on a narrow focused url-pattern, like `/api/*` and leave the other requests for resources to Jetty (it can serve static content WAY BETTER than Jersey can).

IF I have the web.xml then localhost:8080/myresource  works fine
BUT the index.jsp is not picked  with localhost:8080 or http://localhost/index.jsp

STATUS:404

IF I remove the web.xml then the index.jsp is picked up which is what is meant to happen with jetty because it's built in functionality
assumes an index.jsp file is there and will pick it and publish it.
But the I get a 404 with localhost:8080/myresource  now.
I want both index.jsp to be picked up and have the jersey functionality localhost:8080/myresource with the web.xml
but I can only have one or the other.

Preferably I also want the Rest API Config to work as well as the index.jsp so that I can call the resource localhost:8080/v1/myresource

import jakarta.ws.rs.ApplicationPath;
import jakarta.ws.rs.core.Application;

@ApplicationPath("v1")
public class RestAppConfig extends Application{
}
