org.hibernate.InvalidMappingException: Could not p-第2页回答

I know this question has been asked a lot, but I read almost every one of them but non of them helped me. I'm writing an eclipse maven project with hibernate and I'm getting this error:

org.hibernate.InvalidMappingException: Could not parse mapping document from resource ir/ac/ut/ieproj/da/Student.hbm.xml

my files are like this:

import ir.ac.ut.ieproj.model.Department;

public class DepartmentRepo {

    private int id;
    private String name;

    public Department getDeptbyId(String id) throws MappingException, HibernateException, Exception {

        Session session = HibernateUtil.getHibernateSession();
        Transaction tx = session.beginTransaction();
        Query query = session.getNamedQuery("getDeptName").setLong("id", Integer.valueOf(id));
        DepartmentRepo departmentRepo = (DepartmentRepo) query.uniqueResult();
        Department department = new Department();
        department.setName(departmentRepo.getName());

        return department;

    }

    public int getId() {

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

I think the problem is with the many-to-one tag in Student.hbm.xml because Department.hbm.xml and the namedQuery within are not causing an error. What am I doing wrong? I'm using mvn package to make a .war file and then deploy it in tomcat 7.

You just close your property like

<property name="firstName" type="string" column="FirstName" />

<property name="firstName" type="string" column="FirstName"></property>
