Every resource should support the http common operations. Resources are identified by global, iDs (which are typically, uRIs). Rest allows that resources have different representations, e.g., text, XML, json etc. The rest client can ask for a specific representation via the http protocol (content negotiation). Jersey is the reference implementation for the JSR 311 specification. The Jersey implementation provides a library to implement Restful webservices in a Java servlet container. On the server side Jersey provides a servlet implementation which scans predefined classes to identify restful resources. In a rest based architecture everything is a resource. A resource is accessed via a common interface based on the http standard methods. In a rest based architecture you typically have a rest server which provides access to the resources and a rest client which accesses and modifies the rest resources. 2.JAX-RS with Jersey Java defines rest support via the Java Specification Request (JSR) 311. This specification is called JAX-RS (The Java API for restful Web Services). JAX-RS uses annotations to define the rest relevance of Java classes.

ST - Representational State Transfer 1.1.What is rest? Rest is an architectural style which is based on web-standards and the http protocol. Rest was first described by Roy Fielding in 2000. Open the file web. Xml and modify it to the following.?xml version"1.0" encoding"UTF-8"? web-app xmlns:xsi "http www. W3.org/2001/xmlschema-instance" xmlns "m/xml/ns/javaee" xsi:schemaLocation "m/xml/ns/javaee m/xml/ns/javaee/web-app_3_0.xsd" id "WebApp_ID" version "3.0" display-name rst /display-name servlet servlet-name Jersey rest Service /servlet-name servlet-class rvletContainer /servlet-class init-param param-name ckages /param-name param-value rst /param-value /init-param load-on-startup 1 /load-on-startup /servlet servlet-mapping servlet-name Jersey rest Service /servlet-name url-pattern /rest/ /url-pattern. Xml file, augmented with the servlet-mapping URL-pattern and the hello @Path annotation from your class file. You should get the message "Hello Jersey". The browser requests the html representation of your resource.
