"No resource methods" when using JAX-RS on TomEE+
It looks like your resource methods are not public
in scope. Try this:
import javax.ws.rs.*;
import javax.ws.rs.core.Response;
@Path("/test")
public class BaseResource {
@GET @Produces("text/plain") @Path("test") public Response helloWorld() {
return Response.ok("Hello world","plain/text").build();
}
@GET @Produces("text/plain") public String helloWorld2() {
return "Hello world without path!";
}
}

Using stock TomEE+, I cannot get a simple JAX-RS resource to work. I constantly get an error of:

I've tried a number of permutations, adding beans.xml, removing, changing order of the annotations, using different compile dependencies for the Java EE classes. I consistently get this error.
