Question

I’m trying to serialize a list of objects I have in a particular format. The XML structure will be:

<doc>
    <data>
       <item>
          ... object properties go here ...
       </item>
    </data>
</doc>

So far I have the whole structure of an element working properly, but this code below will create it as an XML document itself, I need to be able to loop through my array and add them all to the structure described above.

JAXBContext context = JAXBContext.newInstance(Concern.class);

JAXBElement<Concern> jaxbElement = new JAXBElement(new QName("item"), Concern.class, concerns.get(0));
Marshaller m = context.createMarshaller();

StringWriter sw = new StringWriter();
m.marshal(new JAXBElement(new QName("item"), Concern.class, concerns.get(0)), sw);

Thanks for any help.

You need classes representing the “doc” and “data” tags (say Doc and Data). then you create a Doc instance, add a Data instance to it, and lastly add all your Concern instances to the Data instance. then marshal the Doc instance.
