Jersey, JAX-RS notes for RESTful Web Services Developer's Guide

• RESTful Web Services Developer's Guide
• can embed variables in the URIs. URI path templates are URIs with variables embedded within the URI syntax
• "A fundamental part of REST is that the next set of valid operations is encoded in the response from the last. This means that as long as you only use actions from the last operation you will always perform a valid operation according to the application protocol." - does this feature exist in Jersey?
• "If a character in the value of a variable would conflict with the reserved characters of a URI, the conflicting character should be substituted with percent encoding." - use case?
• If the application needs to supply additional metadata, such as HTTP headers or a different status code, a method can return a Response that wraps the entity, and which can be built using Response.ResponseBuilder.
• By default, a resource class can respond to and produce all MIME media types of representations specified in the HTTP request and response headers
