Question

How do I set the xml namespace when using Jersey, jaxb & jax-rs

Answer 1

This is all done using JAXB annotations. The points below refer to your domain model.

Schema Level

You can specify schema level namespace information using the @XmlSchema package level annotation:

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

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

The above annotation leveraging elementFormDefault will default the namespace of all elements to “http://www.example.org“.

Type Level

You can override namespaces at the type level using the @XmlType annotation:

@XmlType(namespace="http://www.example.org/foo")

Property/Field Level

And/or you can specify namespace information on the annotations themselves:

• @XmlAttribute(namespace=”http://www.example.org/bar”)
• @XmlElement(namespace=”http://www.example.org/bar”)
• @XmlElementWrapper(namespace=”http://www.example.org/bar”)
• @XmlRootElement(namespace=”http://www.example.org/bar”)

Example

I have a blog post that demonstrates these concepts with an example:
