I am new to developing REST API
with Java. I made a very simple one using the mkyong
tutorials, where it only says "hello". I am using Apache Tomcat.
Now I am trying to develop a one where it will return the JSON
objects. I am attempting the example here - http://www.mkyong.com/webservices/jax-rs/json-example-with-jersey-jackson/. Some of the code are changed (ex: package name).Below is my code.
Track.java
package com.tutorialspoint;
/**
*
* @author Yohan
*/
public class Track {
String title;
String singer;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getSinger() {
return singer;
}
public void setSinger(String singer) {
this.singer = singer;
}
@Override
public String toString() {
return "Track [title=" + title + ", singer=" + singer + "]";
}
}
JsonService.java
package com.tutorialspoint;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
/**
*
* @author Yohan
*/
@Path("/json/metallica")
public class JsonService {
@GET
@Path("/get")
@Produces(MediaType.APPLICATION_JSON)
public Track getTrackInJSON() {
Track track = new Track();
track.setTitle("Enter Sandman");
track.setSinger("Metallica");
return track;
}
@POST
@Path("/post")
@Consumes(MediaType.APPLICATION_JSON)
public Response createTrackInJSON(Track track) {
String result = "Track saved : " + track;
return Response.status(201).entity(result).build();
}
}

My application is not a marven
project. So the added libraries are below.
I tested the application with the below URL.
http://localhost:8080/RESTFUL_API_SAMPLE/rest/json/metallica/get
All I got is the below page
Any idea about why I am not getting the expected result?
