Hibernate 3.0
Oracle 9i
I am new to Hibernate (2 days) and am trying to get a one-to-many relationship to work. When I run my code I get the a message about an unmapped class. I'm sure this is simple, but I've been trying to solve this for over a day and am not getting it. I've followed the online documentation correctly (I think), but can't figure out the problem.
Thanks in advance.
Code:
org.hibernate.MappingException: Association references unmapped class: com.maximus.schoolmax.student.model.StudentVaccination

Here is the Java code:
Code:
public Long insertStudent()
{
String id = null;
Student student = new Student();
student.setDistrictNumber(DISTRICT_NUMBER);
student.setExtStudentNumber(EXT_STUDENT_NUMBER);
student.setDateOfBirth(BIRTH_DATE);
student.setFirstName(FIRST_NAME);
student.setMiddleName(MIDDLE_NAME);
student.setLastName(LAST_NAME);
student.setGender(GENDER);
student.setHealthCompliant(new Integer(0));
student.setUpdatedBy(UPDATED_BY);
StudentVaccination sv = new StudentVaccination();
sv.setAgeAtVaccination(4);
sv.setUpdatedBy(UPDATED_BY);
sv.setVaccinationDate(new Date());
sv.setStudent(student);
student.addVaccination(sv);
session.save(student)
Here is the Student.hbm (this is the "1" in the relationship):
