How do I marshal java.util.List with JAXB like JAX-RS (CXF, and Jersey) do [duplicate]

Question

It seems the latest JAX-RS can handle methods returning java.util.List as the XMLRootElement but normal JAXB cannot. I would like to mimic what CXF and Jersey are doing.

In other words I would like to Marshal a List and just like CXF and Jersey do. Normally if you try to marshal a list with JAXB you get the Root Element exception. How do I get around this with out having to make a wrapping object?

EDIT: Thanks for the many answers but I'm very familiar with the @XmlElementWrapper but that does not even come close to simulating what JAX-RS is doing.

JAX-RS does this:

@XmlRootElement(name="dog")
public class Dog {
    private String name;
    public String getName() { return this.name; }
    //Setter also
}

Now if I serialize a list of dogs:

serialize(List<Dog> dogs);

XML should be (what JAX-RS does):

<dogs>
    <dog><name>Rascal</name></dog>
</dogs>

So you can see I don't want to have to make a wrapper object for every single domain object.

Answer 1

Could you not simply add:

@XmlElementWrapper(name = "wrapperName")

No need to make a wrapper object. This will then be the route element in your marshalled XML response.

Answer 2

I used a custom iterable list using the following code, hope this helps.

package bindings;

import java.io.Serializable;
import java.util.Iterator;
import java.util.LinkedList;
import java.util.List;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlType
@XmlRootElement
public class CustomBindList<V> implements Iterable<V>, Serializable {
        private static final long serialVersionUID = 4449835205581297830L;

        @XmlElementWrapper(name = "List")
        @XmlElement(name = "Entry")
    private final List<V> list = new LinkedList<V>();

    public CustomBindList() {
    }

    public void add(final V obj) {
            list.add(obj);
    }

    public V get(final int index) {
        return list.get(index);
    }

    @Override
    public Iterator<V> iterator() {
        return list.iterator();
    }

    public int size() {
        return list.size();
    }
}
