Join Alex Theedom for an in-depth discussion in this video The HTTP response, part of Java EE: RESTful Service with JAX-RS 2.0.
- [Voiceover] Providing a response is an essential part…of the Restful API's role.…The response must be properly formed,…and contain the required information…in the appropriate format.…Let's look at how to construct a response…and how to set the appropriate HTTP Response Code.…HTTP Response Codes are sent to the client from the server…in order to communicate something about…what has happened on the server side.…These codes are three digits long,…and are split into five broad categories of responses.…Those starting with the number one,…indicate that the response includes information…such as the server has agreed to switch protocol.…
Those starting two, indicate that the request…has been performed successfully, and without error.…Those starting three, are also success codes,…but indicate that the client must perform an action,…such as to redirect to another URL.…Those starting with the number four,…indicate that a client error has occurred.…This means that the client is at fault,…and has perhaps requested a page that doesn't exist.…
Join Alex Theedom as he guides you through a wide range of topics, including how to define resource endpoints, how to add dynamism to your application with hypermedia, how to maintain data integrity with Bean Validation, and how to process messages with the JSON Processing API. Once you have completed this course, you'll be ready to develop your own client and server RESTful APIs.
