Jaxb Binding with List returned in web service response

Question

I am developing a jax-ws client, I am trying to handle an ArrayList returned as a response, but i had always empty list.

Returned list is NOT empty, I am sure that WebService provider is returning data in that list, I checked that using SoapUI.

there is generated client related files:

 @XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ArrayOfFact", propOrder = {
    "item"
})
public class ArrayOfFact {

    protected List<Fact> item;
 public List<Fact> getItem() {
        if (item == null) {
            item = new ArrayList<Fact>();
        }
        return this.item;
    }

}

ArrayOfFacts class generated by wsimport it's the same class generated before.

The XML response I receive in SOAPUI :

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Fact class:

    @XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Fact", propOrder = {
    "refImp",
    "mntImp",
    "libImp",
    "flgPaiObl"
})
public class Fact {

    @XmlElementRef(name = "RefImp", namespace = "http://www.test.ma/webservices/WSTesServe/", type = JAXBElement.class, required = false)
    protected JAXBElement<String> refImp;
    @XmlElementRef(name = "MntImp", namespace = "http://www.test.ma/webservices/WSTesServe/", type = JAXBElement.class, required = false)
    protected JAXBElement<String> mntImp;
    @XmlElementRef(name = "LibImp", namespace = "http://www.test.ma/webservices/WSTesServe/", type = JAXBElement.class, required = false)
    protected JAXBElement<String> libImp;
    @XmlElementRef(name = "FlgPaiObl", namespace = "http://www.test.ma/webservices/WSTesServe/", type = JAXBElement.class, required = false)
    protected JAXBElement<String> flgPaiObl;

    // Getters and Setters

}

Answer 1

I fixed that by adding an xml element declaration in class ObjectFactory generated by wsimport

@XmlElementDecl(namespace = "http://www.test.ma/webservices/WSTestServe/", name = "Fact", scope = ArrayOfFact.class)
public JAXBElement<Fact> createArrayOfFactItem(Fact value) {
    return new JAXBElement<Fact>(_ReleveInfoFact_QNAME, Fact.class, ArrayOfFact.class, value);
}

And the list of items should be annotated by :

@XmlElementRef(name = "Fact", namespace = "http://www.test.ma/webservices/WSTestServe/", type = JAXBElement.class, required = false)
protected List<Fact> item;
