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; } } --- In flexcoders@yahoogroups.com, "gordon_greg" <[EMAIL PROTECTED]> wrote: > > Hi. > > I do indeed see that the > flex.data.assembler.HibernateAnnotationsAssembler is provided in the > flex.data.jar file distributed with LCDS 2.6b2. > > However, I have no idea how to get it working: > > I tried modifying the simple Contact demo using Hibernate that comes > as a sample for LCDS 2.6 to use annotations, and then I commented out > the following line in hibernate.cfg.xml: > > > <mapping resource="flex/samples/contact/Contact.hbm.xml"/> > > Then I changed the data-management-config.xml entry for > > <destination id="hibernate-contact"> > > > To use > > <source>flex.data.assemblers.HibernateAnnotationsAssembler</source> > > And I assumed this was all I would have to change to get this working. > > However, when I attempt to start up the server, I simply get errors i.e.: > > [Flex] [ERROR] MessageBroker failed to start: > flex.data.adapters.AdapterException: No Hibernate mapping was found > for entity name 'flex.samples.contact.Contact' configured in > destination 'hibernate-contact'.
