Hi Richard, You don't need to know the index of the object class to make your code work, you can just cast the instance of the class to IMarshallable and call the marshal() method on the object instance. This interface is added by JiBX as part of the binding compile.
Aside from that, in order for the result to be a valid XML document you're going to need to add a wrapper element around all these individual roots. Writing text directly to the output stream is generally not a great way of doing things - another alternative would be to just add writing the XML declaration and the wrapper element start tag inside your loop (after you've gotten the marshalling context, and only when i == 0), then finish with the wrapper element end tag when after writing the root at i == roots.length-1. - Dennis Dennis M.
