Java API for RESTful Web Services (JAX-RS), is a set if APIs to developer REST service. JAX-RS is part of the Java EE6, and make developers to develop REST web application easily.
In this series of JAX-RS tutorials, we use both Jersey and RESTEasy, popular JAX-RS implementation.
You can quick check this Overview of the core JAX-RS concepts, important annotations before practicing examples bellow deeply
Happy learning JAX-RS 🙂
Quick Start
Some quick start examples to use JAX-RS.
- Jersey hello world example
Jersey framework to create a simple REST style web application. - Jersey and HK2 dependency injection (auto scanning)
Jersey framework use HK2 dependency injection framework - Crud operation with REST API using JAX-RS
Jersey based REST APIs for CRUD operations - RESTEasy hello world example
RESTEasy framework to create a simple REST style web application. - RESTEasy Hello World Example Tutorial
Another hello world example to create simple rest web service with RESTEasy - RESTEasy CRUD Example Tutorial
Create a JAX-RS CRUD example with RESTEasy. - RESTEasy Tutorial with Eclipse and Tomcat
Create RESTful web service usiing RestEasy framework and deploy in Tomcat servlet container to test it - RESTEasy CRUD with H2 database tutorial
RESTEasy CRUD tutorial shows how to create a JAX-RS CRUD example with RESTEasy.
