How do I marshal a JAXB object to XOM?

Question

I'm trying to figure out what bits I need to plug together to marshal a JAXB POJO to a XOM document, and vice versa.

The JAXB Marshaller interface's marshal methods take various targets, such as Result, but none of them have a XOM adapter. Irritatingly, the XOM API does have a XOMResult implementation, but it's package protected, and only used internally.

Is there some other way I can marshal to/from XOM without resorting to String or byte buffers?

I'm not sure if you are adverse to using DOM to accomplish this, as you're probably using XOM to avoid DOM! Anyway, using a JAXB Binder as described here along with XOM's DOMConverter, you can go from JAXB to DOM to XOM without using a String or a byte buffer.

It is too bad that XOM doesn't have a utility to create a XOM Document from a SAX ContentHandler, since JAXB also supports marshalling to an instance of that object. XOM has a SAXConverter that can create a ContentHandler from a Document, but not the other way around.

Here's a thread that relates to this on the XOM-interest mailing list.
