REST Webservice returning 415 - Unsupported Media Type

I've created a REST webservice using jax-rs and jersey that is supposed to consume JSON on a POST request. My web service class looks like this:

@Path("/webhookservice")
public class Webhook {

@POST
@Consumes(MediaType.APPLICATION_JSON)
public Response readData (Song song) {

// Prints out the song info
System.out.println("SONG INFO \n=======================");
System.out.println("songname: " + song.getSongname());
System.out.println("artist: " + song.getArtist());

// Repsonse with a HTTP 200 OK
Response response = Response.status(200).build();
return response;

}

}


My Song class:

public class Song {

private String songname;
private String artist;

public String getSongname () { return this.songname; }
public String getArtist () { return this.artist; }

public void setSongname (String songname) { this.songname = songname; }
public void setArtist (String artist) { this.artist = artist; }

}


My web.xml (if needed)

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I'm using RESTClient a little, well, rest client... Here's a screenshot of what I'm sending:

When I send that off, I get the 415 Unsupported Media Type error. Anybody have an idea why?

Answer

You need to send the request-header Content-Type: application/json. Seems like REST-Client does not add this header automatically for you.
