Hibernate code is

public void getAll() {

    Session session = HibernateUtil.getSessionFactory().openSession();
    Transaction transaction = null;
    try {
        transaction = (Transaction) session.beginTransaction();
        List employees = session.createQuery("from Employee").list();
        for (Iterator iterator = employees.iterator(); iterator.hasNext();) {
            Employee employee = (Employee) iterator.next();
            System.out.println(employee.getName());
        }
        transaction.commit();
    } catch (HibernateException e) {
        transaction.rollback();
    } finally {
        session.close();
    }
}

Employee.java

@Entity
@Table(name="employee")
public class Employee {

private int id;
private String name;
private String email;
private String address;
private int managerId;


@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id)")
public int getId() {
    return id;
}

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

@Column(name="emp_name")
public String getName() {
    return name;
}

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

@Column(name="emp_email")
public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

@Column(name="address")
public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

@Column(name="manager_id")
public int getManagerId() {
    return managerId;
}

public void setManagerId(int managerId) {
    this.managerId = managerId;
}
}

Answer 1

this

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id)")
public int getId() {
    return id;
}

should be - 

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id")
public int getId() {
    return id;
}

Remove ) from the end of name="emp_id)"
