Allow me to answer my own quetions:
1) rather removing the <mapping> line from hibernate.cfg.xml, I had to
replace it with
<mapping class="flex.samples.contact.Contact"/>
2) had to ensure the the named query "all" was defined at the top of the
Contact class i.e.
@NamedQuery(name="all", query="From Contact")
That pretty much did it - required no other changes to the
data-management-config.xml other than specifying
HibernateAnnotationsAssembler...
And for any one out there who may care, the following is the full
Contact.java class modified to use annotations:
package flex.samples.contact;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
@Entity
@Table(name="contact")
@NamedQuery(name="all", query="From Contact")
public class Contact {
private int contactId;
private String firstName;
private String lastName;
private String address;
private String city;
private String state;
private String zip;
private String country;
private String email;
private String phone;
private String notes;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="contact_id")
public int getContactId() {
return contactId;
}
public void setContactId(int contactId) {
this.contactId = contactId;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Column(name="first_name")
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
@Column(name="last_name")
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getZip() {
return zip;
}
public void setZip(String zip) {
this.zip = zip;
}
}
