I inititally had a XML schema that allowed as the root element a single
entity ("package"). This package can be composed of other several
subelements and set of attributes. (In my example below, I removed all the
subelements an attributes except one called "classes" and "class").
But, I need to marshall not only elements of the "package". I would like to
be able to produce documents that only contain a subelement. Then, I
modified my schema to allow also the subelements to be a root element.
Nevertheless, I still cannot marshal to a new document a subentity.
Is it possible to marshal to XML a subeentity of a document ?
I want to use the same XML format of the subelements for use in clipboard
operations.
But so far, I can't marshall a subelement correctly. It seems that
eventhough I defined them as valid root elements <xsd:element> they are
treated as "types" when parsing a document containing them (package).
I'm not sure I'm being clear on my question, so I am including some code
and the output I was expecting.
Thanks

I'm getting:
Marshalling a classes:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<class name="test" xmlns="
http://www.on.com/xml/schemas"/>
<class name="sample" description="A class description goes here."
xmlns="
http://www.on.com/xml/schemas"/>
Marshalling a class:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

This is the Java code I have:
jaxbContext = JAXBContext.newInstance(JAXB_PACKAGE,
ClassLoader.getSystemClassLoader());
unmarshaller = jaxbContext.createUnmarshaller();
marshaller = jaxbContext.createMarshaller();
validator = jaxbContext.createValidator();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, new
Boolean(true));
PackageElement pkg = (PackageElement) unmarshaller.unmarshal( new
File("d:/projects/java/dsrts/samples/sample_3.xml"));
System.out.println("Marshalling a classes: ");
marshaller.marshal( pkg.getClasses() , System.out );
Iterator iter = pkg.getClasses().getClazz().iterator();
ClassType ct;
while(iter.hasNext() ) {
ct = (ClassType) iter.next();
System.out.println("Marshalling a class: ");
marshaller.marshal( ct , System.out );
}

Installs application Sample.
You will require Application Ver 2.4 CD to populate the depot and make this
package usable.
