错误 [org.jboss.resteasy.resteasy_jaxrs.i18n]（默认任务 2）RESTEASY002010

Question

I am facing the following problem and I can't find solution to resolve it.

My stacktrace goes here:

ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-2) RESTEASY002010: Failed to execute: javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: http://localhost:8080/myProjectName

Application class :

@ApplicationPath("/")
public class LauncherWebServices extends Application{
}

Class with services

@Path("/folders")
@RequestScoped
public class PageServicesREST {
       @GET
    @Path("/retrievePage")
    @Produces(MediaType.APPLICATION_JSON)
    public Response getListPage() {
        List<Page> list = pageBusiness.retrievePage();
        if (list == null) {
            return Response.ok().entity("Liste des pages est vide").build();
        }
        return Response.ok().entity(pageBusiness.retrievePage()).build();
    }
}

Now, when I am running the application,I got this error (stacktrace) like this url : http://localhost:8080/myProjectName

But when I tried to run a service like below:

http://localhost:8080/myProjectName/folders/retrievePage

it is working fine .

What did i missed ?

I have tried reading other solutions in stackoverflow, and documentation RESTEASY but I can't find the solution. Did anybody come across such an issue ?

Answer 1

Your error message in my opinion is not a fatal one. You got that error because you're not mapped your root URL (/). To avoid that you can mapped your root URL to something, for example:

@Path("/")
@RequestScoped
public class Root {
    @GET
    public Response index() {
        return Response.ok().build();
    }
}

Edited: Instead of mapping root URL on same class, put it on another class since your PageServiceREST already specify folders path.
