2. eclipse new project
    1. new project
        Dynamic Web Project

    2. Tomcat Server Configuration
        Window-Preferences-Servers-Runtime Environments-Add
            기존설치된 TomcatServer를 설정한다.( 또는 Eclipse환경의 기본 Tomcat을 이용할 수 있다.)

    3. import WEB-INF\lib jersey lib

3. Writing Source Code
    1. New (Ctrl-N)
    2. Hello.java
        package sample.test;

        import javax.swing.JOptionPane;
        import javax.ws.rs.GET;
        import javax.ws.rs.Path;
        import javax.ws.rs.Produces;
        import javax.ws.rs.core.MediaType;

        // POJO, no interface no extends

        //Sets the path to base URL + /hello
        @Path("/hello")
        public class Hello {

            // This method is called if TEXT_PLAIN is request
        @GET
        @Produces(MediaType.TEXT_PLAIN) 
        public String sayPlainTextHello() {
            //JOptionPane.showMessageDialog(null, "GET CALLED");	
            return "Hello test~~!!!!!!!!!!!!";
        } 

        // This method is called if XMLis request
        @GET
        @Produces(MediaType.TEXT_XML)
        public String sayXMLHello() {
            return "" + " Hello Jersey" + "";
        }

        // This method is called if HTML is request
        @GET
        @Produces(MediaType.TEXT_HTML)
        public String sayHtmlHello() {
            JOptionPane.showMessageDialog(null, "GET CALLED");	
            return " " + ""
            + "
" + "Hello Jersey" + "
                






                
                




                
" + " ";
            }

        }
    3. jersey 관련 jar파일을 포함시킨다.

4. configuration
    1. WEB-INF/web.xml 수정
        "1.0" encoding="UTF-8"?>
        "http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
         sample.test
          
            Jersey REST Service
            class>com.sun.jersey.spi.container.servlet.ServletContainerclass>
            
              com.sun.jersey.config.property.packages
              sample.test
            
            1
          
          
            Jersey REST Service
            /rest/*
          
        
    2. WEB-INF/lib에 jersey 관련 jar파일 추가
    3. Tomcat Server Restart
    4. Test
        http://localhost:8080/hanlib/rest/hello

# TestTool
    0. netbean설치시 포함되었던 테스트 도구
        K:\TexTa\프로그램_텍스트정리\jax-rs_restFul문서\netbean테스팅도구이용
        index.html에서
        14 LINE 을 수정해서 이용하면됨
            --> var baseURL = "http://localhost:8080/hanlib/||ServletAdaptor||/rest/*";

    1. firefox plugin poster
