I have a similar requirement which is to remove unused namespaces from SOAP message dynamically. As Daniel indicated " JAXB adds namespaces prefixes on the root for every namespace it knows about so it doesn't have to do it later" JAXB adds namespace prefixes based on service xml schema.
A real SOAP message normally does not contains every xml element defined by schema because optional XML element does not show up if it does not have data. Therefore the namespaces of unused xml elements in the message are not needed. I have a web service having 250+ namespace (huge isn't it?). The SOAP message contains 250+ line namespace prefix regardless how many elements being used in SOAP message. To reduce a SOAP message size, I am looking for a way to dynamically remove unused namespace prefix based on the xml elements used in the SOAP message. Since each SOAP message uses different set of elements, unused namespaces are different accordingly. What I did in AXIS world is to add a handler to find out unused namespace and remove them. Is there way I can do it in CXF JAXB?

JAXB adds namespaces prefixes on the root for every namespace it knows about so it doesn't have to do it later. Unfortunately, it's also not easy to "change" that behavior. CXF's JAXB data binding has two maps on it that can be used to adjust some of the namespaces. One or both might be modifiable to test this. If you grab the DataBinding object out of the client, you should be able to call either: void setNamespaceMap(Map<String, String> namespaceMap) or public void setContextualNamespaceMap(Map<String, String> contextualNamespaceMap) to put in a map of URI to prefix. I know they allow complete control over what the prefixes that are used (instead of ns6, ns7, etc...), but I also believe that if they are specified, JAXB doesn't output all of them up front. Not 100% sure on that though.
