A new student record is added by performing the POST operation on this resource. The representation for the new student should be represented in XML. A student record is updated by performing a PUT operation on the student resource.

public class StudentResource { public void add(Student s) { ... }; public Student retrieve(long cwid) { ... }; public void update(String cwid, Student s) { ... }; public Student[] retrieveAll() { ... }; }
