问题
I was following a tutorial on https://www.youtube.com/watch?v=dmMdLW92hBA.
Everything was going fine until the last part where the index.xhtml was introduced in the project.
I get a 404 error in the browser and in the wildfly console log I get the following error:

回答1:
I downloaded the code base as well as WildFly 10.1.0.Final server. I was also facing the same issue.
Root Cause: The annotations @ApplicationPath and @Path are used in the same class that was creating the issue.
@ApplicationPathis used to provide base URI path for the total application.@Pathis used for individual URI path for custom controller class or class methods.
This RestService.java class was creating problem.
Modify the RestService.java (remove @ApplicationPath from this class) :
@Path("/MyRestService")
public class RestService {
// http://localhost:8080/RestExample/resources/MyRestService/sayHello
@GET
@Path("/sayHello")
public String getHelloMsg() {
return "Hello World";
}
@GET
@Path("/echo")
public Response getEchoMsg(@QueryParam("message") String msg) {
return Response.ok("Your message was: " + msg).build();
}
@GET
@Path("/object")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public SimpleObject getObject() {
return new SimpleObject(1, "Test");
}
}
I have added a new class RestApp.java. The code :
@ApplicationPath("/resources")
public class RestApp extends Application {
}
Updated project structure :
