What is the best marshalling program in Spring to do this (JAXB, Castor, etc), and how do I do this? Does this have a name so that I can google for more information about it? Also, I would need to unmarshall the XML back to
java, such that I get an employee with a reference to a department, but only the ID of the department would be filled.
