XML serialization via javax.xml.bind

I am using javax.xml.bind.* (which I believe you call JAXB) to serialize some fairly complex classes to XML.

My issue is that I seem to have to list namespaces everywhere I use a particular element. See:

@XmlRootElement(namespace="http://www.example.org/mynamespace")
public class Root {

    @XmlElement(namespace="http://www.example.org/mynamespace2")
    public Ele ele1;

    @XmlElement(namespace="http://www.example.org/mynamespace2")
    public Ele ele2;
}

public class Ele {

    @XmlAttribute
    public String attrib = "myattri";

    @XmlValue
    public String value = "value";
}

What I would prefer is for Ele to specify the namespace, so that I dont have to specify it everywhere else...

...is this possible?

This is actually based the link in Blaise Doughan's comment.

Package Level Metadata

We can easily qualify all the elements through the use of the package level annotation @XmlSchema. To specify a package level annotation, create a class called package-info in the desired package (see complete source below for an example). Below we will set a default namespace and specify that by default all elements are namespace qualified.

I can add a package-info.java to the example.ele package with the following in it:

@XmlSchema( 
    namespace = "http://www.example.org/mynamespace2", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package example.ele;

and put Ele in the example.ele package.
