Is it possible to customize the namespace prefix that JAXB uses when marshalling to a String?

Question

For example, I\'ve got a simple schema which imports another schema. The second schema (urn:just:attributes, just-attributes.xsd) just defines an attribute group.

This shows how to do it.

Key bits in case that link dies too:

the NamespacePrefixMapper class, found in the com.sun.xml.bind.marshaller package. The abstract class has one method to implement:

public abstract String getPreferredPrefix(  
     String namespaceUri,         
     String suggestion,         
     boolean requirePrefix); 

then

Marshaller marshaller =        
    jaxbContext.createMarshaller();        
marshaller.setProperty(”com.sun.xml.bind.namespacePrefixMapper”,        
    new MyNamespacePrefixMapper());  

If you’re also using javax.xml.xpath.XPath, your NamespacePrefixMapper can also implement javax.xml.namespace.NamespaceContext, centralizing your namespace customization in a single class.
