Deploying JAX-RS 2.0 applications to Liberty
You can use Java™ API for RESTful Web Services
(JAX-RS) to develop services that follow Representational State Transfer (REST) principles. RESTful
services are based on manipulating resources. Resources can contain static or dynamically updated
data. By identifying the resources in your application, you can make the service more useful and
easier to develop. Liberty provides
jaxrs-1.1 and jaxrs-2.0 to support the JAX-RS programming model.
Asynchronous processing Configuring a resource to receive multipart/form-data parts from an HTML form submission in JAX-RS 2.0 Configuring JAX-RS 2.0 client Deploying EJB in an EAR file for JAX-RS 2.0 Liberty , JAX-RS 2.0 supports EJB JAX-RS in EJB JAR file that must be included in an EAR file.Implementation of JAX-RS 2.0 web applications Implementation of secure JAX-RS applications WebSphere® Application Server environment, the lifecycle of servlets is managed in the web container. Therefore, the security services that are offered by the web container are applicable to REST resources that are deployed to WebSphere Application Server .JAX-RS 2.0 behavior changes Liberty supports JAX-RS 2.0. Before beginning to use JAX-RS in Liberty , you might need to know the following differences between JAX-RS 1.1 and JAX-RS 2.0.JAX-RS 2.0 integration with Atom JAX-RS 2.0 integration with EJB and CDI Liberty integrates with Enterprise JavaBeans (EJB) and Contexts and Dependency Injection (CDI).JAX-RS 2.0 integration with managed beans Liberty supports the use of managed beans as root resource classes, providers, and application subclasses.Sending multiple query parameters from Client - Cascaded or Iterated programming Using JAX-RS 2.0 context objects to obtain more information about requests @Context annotation to inject context objects such as HttpHeaders, UriInfo, HttpServletRequest into class field or method parameter in application subclasses, root resource classes, and providers.WADL2JAVA command wadl2java command line tool processes an existing Web Application Description Language (WADL) file and generates the required artifacts for developing Java API for RESTful Web Services (JAX-RS) web service applications. The wadl2java command line tool supports the top-down approach to developing JAX-RS web services. When you start with an existing WADL file, use the wadl2java command line tool to generate the required JAX-RS artifacts.
