JAXB - unmarshalled fields are null

Question

We are unmarshalling a response from http://xmlgw.companieshouse.gov.uk/. This is the text sent to the marshall:

Answer 1

I figured out the correct answer thanks to @Blaise Doughan. After looking at the package namespace qualification I found that it was pointing to:

"http://xmlgw.companieshouse.gov.uk/v1-0"

and it should have been pointing to:

"http://xmlgw.companieshouse.gov.uk/v1-0/schema"

Not sure how that got misplaced.

Answer 2

You need to use a package level @XmlSchema annotation to specify the namespace qualification for your model.

@XmlSchema(
    namespace = "http://xmlgw.companieshouse.gov.uk/v1-0/schema",
    elementFormDefault = XmlNsForm.QUALIFIED)
package example;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

This this specified you do not require to specify the namespace URI on the @XmlRootElement and @XmlType on your NameSearch class.

The unmarshaling is done from the first Node extracted from a larger Document, inside an any list of items.

Make sure the DOM parer used to create the nodes is namespace aware.

documentBuilderFactory.setNamespaceAware(true);

Answer 3

I solved this by making elementFormDefault="unqualified" in the xsd before generating stubs, else make the change manually in package-info.java
