REST WS: 415 - Unsupported Media Type Error

[201042410]

Hello,

I am tring to follow your tutorial step by step building a poll and
have been successful so far, however, I am now stuck:

1. On my client side I have transformed my java object to JAXBElement
-JAXBElement<Poll> jaxbPoll = new JAXBElement<Poll>( new
QName("poll"), Poll.class, poll );
-ClientResponse resp = service.put( ClientResponse.class ,
jaxbPoll );

2. On the PollResource side, I receive a JAXBElement<Poll> parameter
-public Response createPoll( JAXBElement<Poll> jaxbPoll ){}

3. My Poll object looks like this:

package rest;

import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement( name="poll" )
public class Poll
{
private int id;
private String question;

private static int index = 0;

public Poll()
{
index += 1;

setId( index );
}

private void setId( int id )
{
this.id = id;
}

@XmlAttribute( name="pollId" )
public int getId()
{
return id;
}

public void setQuestion( String question )
{
this.question = question;
}

@XmlElement()
public String getQuestion()
{
return this.question;
}
}

I then receive a 415 error and the information below:

14 Jan 2011 4:48:09 PM com.sun.jersey.spi.container.ContainerRequest

Please help me solve this problem, how do I convert my objects to a
recognized MIME type?
