Hi Francois, That will work, but you can actually get the equivalent effect without needing to modify the supplied code.
The IUnmarshallingContext and IMarshallingContext setup calls are all modular, and the JavaDocs spell out the effects of the different calls to point you in the direction of doing your own compositions. So the three-argument marshalDocument() call, for instance, says: /Marshal document from root object. This can only be validly called immediately following one of the set output methods; otherwise the output document will be corrupt. The effect of this method is the same as the sequence of a call to startDocument(java.lang.String, java.lang.Boolean), a call to marshal the root object using this context, and finally a call to endDocument()./ This doesn't spell it out, but what do you suppose would happen if rather than calling this method you instead called startDocument(), followed by multiple calls to marshal objects, followed by the endDocument() call? The result wouldn't be valid XML (since you'd have more than one root element in the "document"), but it would be what you want. One thing that's not spelled out in the interface is how you actually marshal an object directly. This is really simple, though. Any class with a concrete mapping gets the IMarshallable interface added by the binding compiler. You just need to cast your instance object to this interface and use that for the marshalling call. But once you have your output with the multiple XML documents concatenated together you're going to have a problem reading it back in, since the unmarshalling side expects to work with individual documents (and since the parsers enforce this requirement, it's not something that can be changed by the unmarshalling code).
