This should be easy, but it's been costing me tons of time. I basically can't get a RESTful web service running under eclipse. I'm sure I'm missing something stupid, but resources seem to be a bit scattered and nothing covers the recent 4.0/EE 7 release.
I have a clean install of Eclipse Kepler (4.3). I try and set up a basic RESTful app using the following steps.
I have Java EE 7 installed
I open eclipse, point it to a fresh workspace and create a new 'Dynamic Web Application'.
Project name doesn't particularly matter, a new Target Runtime is created by downloading the Glassfish extension (New Runtime->Download additional server adapters->Glassfish). This requires restarting eclipse - so just repeat the previous, but select a Glassfish 4.0 runtime after clicking 'New Runtime'. Web Module is 3.1, everything else is default. I click 'Finish' to create my new project.
I then right click and open project properties, then 'Project Facets'. I check of JAX-RS (REST Web Services). Then click 'Further Configuration required...". I then select 'Disable Library Configuration' from the drop down. The fields receive the following values:
JAX-RS servlet name: JAX-RS Servlet
JAX-RS servlet class name: org.glassfish.jersey.servlet.ServletContainer
URL mapping patterns: /jaxrs/*
I then click OK to close all the windows.
Now adding a New->'RESTful Web Service from Pattern' creates a new class, that doesn't seem to ever get picked up by glassfish on deployment. My understanding is that it should auto scan and pick up things with an @path. It doesn't seem to. If I finagle things enough I can seem to access the application.wadl - but doesn't show my resource.
If I go back into properties and take a look at my JAX-RS project facet, I'm presented with an error box saying some of my values are invalid.
In the workspace log I'm greeted with the following exception:

Any insight would be so greatly appreciated.
