I’m developing a JERSEY RESTFUL web service which has a function that accept an object parameter. It is called “Synchronize” and looks like this:

@XmlRootElement
public class Synchronize {

private List<PHQ9> phq9OutOfSync;
private List<ExtraQuestions> extraQuestionsOutOfSync;
private List<Suicide> suicideOutOfSync;
private List<Brugha> brughaOutOfSync;
private int hola;

public Synchronize() {

    phq9OutOfSync = new ArrayList<PHQ9>();
    extraQuestionsOutOfSync = new ArrayList<ExtraQuestions>();
    suicideOutOfSync = new ArrayList<Suicide>();
    brughaOutOfSync = new ArrayList<Brugha>();
}
}

The problem is I am not able to send a xml with the serialization of this class to the web service. I send an xml with all the attributes but it doesn’t deserialize it well… I don’t know if it is because the Lists that are doing some problems or so. I even tried sending only the int attribute like:

<synchronize><hola>1</hola></synchronize>

and doesn’t work too… What is going on?

Any hints?

EDIT: I’m seeing that I don’t know how I can refer to an attribute that is in a class. I tried making a web service that accepts a list with phq9 objects, and it works great, but if I put that list in other class, then it doesn’t know how to deserialize. Why could it be?

EDIT2:

@XmlRootElement
public class PHQ9 {

@XmlElement
private int id;
@XmlElement
private int patientId;
@XmlElement
private int answer1;
@XmlElement
private int answer2;
@XmlElement
private int answer3;
@XmlElement
private int answer4;
@XmlElement
private int answer5;
@XmlElement
private int answer6;
@XmlElement
private int answer7;
@XmlElement
private int answer8;
@XmlElement
private int answer9;
@XmlElement
private int answer10;
@XmlElement
private int total;
@XmlElement
private int week;
@XmlElement
private String phq9Date;
@XmlElement
private String timeExported;
@XmlElement
private String dateExported;
@XmlElement
private int exported;

public PHQ9() {

    phq9Date = timeExported = dateExported = "";        
}
}

    [EDIT]

    In regards to lists, take a look at JAXB: How to marshal objects in lists? on how to wrap lists, if desired.

    You can limit which members are to be serialized using XmlAccessorType (http://docs.oracle.com/javaee/5/api/javax/xml/bind/annotation/XmlAccessorType.html) and XmlElement (http://docs.oracle.com/javaee/5/api/javax/xml/bind/annotation/XmlElement.html).

    It is possible you are trying to serialize/deserialize an unsupported class, causing it to fail. Are you getting any exceptions or is it just failing silently? Have you tried taking a look at the raw data being sent/received?
