Following a discussion with Koen on the ml, here is an issue to check if the WtServlet serves wt-resources correctly.

I had to implement it this way in Jruby:

    @server = Server.new(8080)
    # get external path for resources in jar
    static_content=@server.getClass().getClassLoader().getResource("eu/webtoolkit/jwt/wt-resources").toExternalForm()
    # create a web context, and define where the resources will be available
    # the prefix has to be the same as for the servlet holder below
    web_context=WebAppContext.new(static_content, '/wt-resources')
    context = ServletContextHandler.new(ServletContextHandler::SESSIONS)
    context.addEventListener(ServletInit.new);
    servlet = HelloMain.new()
    holder = ServletHolder.new(servlet)
    context.addServlet(holder, '/')
    handler_list= HandlerList.new
    handler_list.setHandlers([web_context,context])
    @server.setHandler(handler_list);
