I am new to Jaxb and this is my first time using it. I have an xml that I would like it to be translated into my existing objects. I succeeded with simple attributes and elements, however with collections I am getting empty collections back.

I want to generate a Copyright Holder instance with an xml. I create an http post method to send the xml and use annotations to unmarshall it. To generate the post method I am using an firefox plugin called Poster. All collections from CopyrightHolder fail to load. (PS:Contracts collection is not mapped). The call to the post method works, the copyright holder is created but with all collections empty. I think I’m missing something with the annotations.

Any help is appreciated.

Your namespaces are messed up. For example:

@XmlElementWrapper(name="Contacts", namespace="http://www.example.org/common")
@javax.xml.bind.annotation.XmlElement(name="Contact", namespace="http://www.example.org/common")
public Set<CopyHolderContacts> getCopyHolderContacts() {
    return this.copyHolderContacts;
}

In your XML document, the Contacts wrapper element has the http://www.example.org/copyrightholder namespace.

Try changing it to

@XmlElementWrapper(name="Contacts", namespace="http://www.example.org/copyrightholder")
@XmlElement(name="Contact", namespace="http://www.example.org/common")

And similarly for the other collections.
