What is a JAX-RS application?
What is a JAX-RS application?
JAX-RS is a Java programming language API designed to make it easy to develop applications that use the REST architecture. The JAX-RS API uses Java programming language annotations to simplify the development of RESTful web services.
What is a JAX-RS provider?
Providers are a simply a way of extending and customizing the JAX-RS runtime. You can think of them as plugins that (potentially) alter the behavior of the runtime, in order to accomplish a set of (program defined) goals.
What is an implementation of JAX-RS specification?
While JAX-RS provides a faster way of developing web applications than servlets, the primary goal of JAX-RS is to build RESTful services. A server-side component API is defined in jaxrs-1.1 and jaxrs-2.0 to build REST applications. IBM® JAX-RS provides an implementation of the JAX-RS (JSR 311) specification.
What are the JAX-RS annotations?
JAX-RS Annotations
| Annotation | Description |
|---|---|
| POST | specifies method responds to POST request. |
| PUT | specifies method responds to PUT request. |
| HEAD | specifies method responds to HEAD request. |
| DELETE | specifies method responds to DELETE request. |
What is your understanding in JAX-RS?
JAX-RS is a JAVA based programming language API and specification to provide support for created RESTful Web Services. Its 2.0 version was released on the 24th May 2013. JAX-RS uses annotations available from Java SE 5 to simplify the development of JAVA based web services creation and deployment.
What is the difference between JAX WS and JAX-RS?
Actually,JAX-WS represents both RESTful and SOAP based web services. One way to think about it is that JAX-RS specializes in RESTful, while JAX-WS allows you more flexibility to choose between either, while at the same time being (in some cases) more complicated to configure. Thank you for simple explanation.
Which of these are implementations of JAX-RS API?
JAX-RS is a standard defined in Java Specification Request 311 (JSR-311) and Jersey / RESTEasy are implementations of it.
What is the difference between @produces and @consumes?
@Consumes specifies what MIME type a resource accepts from the client. @Produces , however, specifies what MIME type a resources gives to the client. For example, a resource might accept application/json ( @Consumes ) and return text/plain ( @Produces ).
Which of the following is the JAX-RS reference implementation?
Jersey
Jersey – the JAX-RS Reference Implementation from Sun. RESTEasy – JBoss’s JAX-RS project. Restlet – probably the first REST framework, which existed prior to JAX-RS.
Which part of JAX-RS should the developers focus on?
JAX-RS focuses on applying Java annotations to plain Java objects. JAX-RS has annotations to bind specific URI patterns and HTTP operations to specific methods of your Java class. It also has annotations that can help you handle input/output parameters.
What are the goals of JAX-RS?
The Goals of JAX-RS Format independence: To be applicable to a wide variety of HTTP entity body content types and provide the necessary pluggability to allow additional types to be added. Container independence: To ensure that artifacts using the API are deployable in a range of Web servers.
