Unsupported Media Type - HTTP Status 415

Question

I have a problem with my web service. GETrequests are executed correctly and correctly, but the mail request receives HTTP status 415.

The project I'm working on is a JAX-RS RESTful API that will need to communicate with the Android mobile application. I can get information from the instructions GET.

This is the code of my object LoginFormat:

@XmlRootElement
public class LoginFormat {

    private String username;
    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

Here you can see a sample of POSTmy class CoCreationService:

@Path("/User")
public class CoCreationService {
    @POST
    @Path("/testLogin") 
    @Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    @Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
    public Response parseTerm(LoginFormat login) {  

        return Response.status(200).entity(login.getUsername() + login.getPassword()).build();  
    }
}

I tried so much that they confuse me.

I tested the curl of a web service:

curl -i -X POST -H 'Content-Type: application/json' -d '{"username": "testuser", "password": "test"}' http://localhost:8080/CoCreationService/api/User/testLogin

Is there any tweak that needs to be mentioned, or have I made a critical mistake?

PS: I work with NetBeans.

Edit: POST with / plain text works!

@POST
@Path("/testPost")
@Consumes("text/plain")
public Response postClichedMessage(String message) {       
    return Response.status(200).entity(message).build();
}
