Java – with restlets, xStream annotations don’t seem to have any effect

Using @ xstreamomitfield in my POJO doesn't seem to have any impact Annotated fields are still exposed in XML or JSON representations

@XStreamAlias("Pojo")
@Entity
public class Pojo {
    private String name;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long key;

    @XStreamOmitField
    private String hidden;

    public Pojo(String name,String hidden) {
        this.name = name;
        this.hidden = hidden;
    }
}

And in serverresource

@Get
public Pojo test() {
    Pojo pj= new Pojo("hansi","hinter");
    return pj;
}

Get me

<com.myComp.ORMTest.Pojo>
  <name>hansi</name>
  <hidden>hinter</hidden>
</com.myComp.ORMTest.Pojo>

Why are any comments ignored?

Solution

You must tell xStream to explicitly handle comments:

XStream xstream = new XStream();
xstream.processAnnotations(MyClass.class);

Alternatively, you should add this code to tell xStream to handle all comments:

xstream.autodetectAnnotations(true);
