So I have been able to code my service using JAX-RS and I get propery
XML back and can send it. All peachy.
Now, once the XML is on the client side, I need to reconstruct the
objects that were transferred.
JAXBContext jc = JAXBContext.newInstance( User.class );
Unmarshaller u = jc.createUnmarshaller();
User lUser = (User)u.unmarshal(new ByteArrayInputStream(
s.getBytes() ) );
System.out.println(lUser);
Ok there too. So.
Then it got me thinking... That unmarshalled object is using the
original class definition that was marshalled before (this is inside a
unittest, so both the server and the unittest access the same User
class). But I do not want my client to use my original class; these are
fairly complex classes which are interlaced with JPA code. For example
methods like "getGroups()" which required new entities which may not
have been send as XML. What I really would require is a shell-class that
only contains the stuff that JAXB has (un)marshalled, but is "XML
compatible" with the actual business class.
I know that JAXB can create Java classes based on an XML-Schema, but I
do not have an XML schema, only annotated classes, and I do not like to
have duplication.
1. Is there a way to convert annotated classes to an XML-schema so that
can be used to generated shell-classes?
2. does anyone have a suggestion on how else to handle this
don't-want-my-domain-objects-made-available-to-the-client?
