In that case, I'll need to see your java code where you set up the
DOMResult and invoke the transform. Are you using a Node in your
DOMResult constructor? If so, is it a Document Node? If so, does it
already have a child Element? If so, that is your problem because your
DOM structure already has a document element so when XalanJ tries to add
another you get the "Can't have more than one root on a DOM!" message.
In any event, I'll be able to tell more when I see your Java code.
Thanks,
