JAXB unmarshall xml without package-info.java

JAXB unmarshaller throws exception if there is no package-info.java file. This code is called from another language and custom classloader can not load package-info properly.

I had already manually added the namespace parameter to all the @XmlElement annotations.

Xml root element has multiple xmlns attributes. Two of them (xmlns and xmlns:c) have the same value (I can not change xml, which is comeing from external service)

BUT: It works if I remove xmlns="urn:foo:bar" from document even without package-info

The question: how can I unmarshall without package-info (I can not modify custom classloader which can not load it) and without removing xmlns from xml ? What should I change in my code?

Java 1.6_45 vJAXB 2.1.10

XML root element sample:

<?xml-stylesheet type="text/xsl" href="file1.xslt">
<?xml-stylesheet type="text/xsl" href="file1.xslt"?>
<c:ClinicalDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="urn:foo:ba" xmlns:c="urn:foo:bar" xmlns:std="urn:foo:std"
 xsi:schemaLocation="urn:foo:bar file2.xsd">

Code:

String path = "D:\\data\\document.xml";

    try {
        JAXBContext jc = JAXBContext.newInstance(ObjectFactory.class);
        Unmarshaller u = jc.createUnmarshaller();
        Object root = u.unmarshal(new File(path)); //exception w/o package-info.java

        CDocument doc= (CDocument) JAXBIntrospector.getValue(root);
        System.out.println(doc);

package-info.java

@javax.xml.bind.annotation.XmlSchema(namespace = "urn:foo:bar", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    xmlns={@XmlNs(namespaceURI = "urn:foo:bar", prefix = "")})
package test.model;

    import javax.xml.bind.annotation.XmlNs;

Exception:

javax.xml.bind.UnmarshalException: Unable to create an instance of my.package.here.model.ANY

Any ideas will be greatly appreciated, I had spent so much time trying, but still have nothing.

This means that you have not added the namespace parameter everywhere you need to.

In the XML document below without the @XmlSchema annotation to map the namespace qualification, you would require the namespace parameter on the @XmlRootElement annotation for the Foo class and the @XmlElement annotation on the bar property.

<foo xmlns="http://www.example.com">
    <bar>Hello World</bar>
</foo>
