UnrecognizedPropertyException: Unrecognized field “start” (Class org.jboss.resteasy.spi.ResteasyProviderFactory), not marked as ignorable

Question

(We could do with a jboss7.x tag now).

Does anyone know what might cause the error below?

start is a field within a JSON object I'm trying to send to my resteasy Application.

The javascript which sends the request:

$.ajax({
    url: '/appointment-web/events/get',
    data: JSON.stringify({
        start: Math.round(start.getTime()/1000),
        end: Math.round(end.getTime()/1000)
    }),
    contentType: "application/json",
        dataType: "json",
        type: "POST"
}).success(function(response) {
    eval(response);
    callback(events);
});

It never makes it through resteasy then on the server side before throwing this error:

Answer 1

It seems this was down to defining the ApplicationPath and the Class level Path within the same Class. Separating them out seems to have resolved it.
