org.hibernate.AnnotationException: No identifier specified f

skidvd · **Joined:** Fri Dec 28, 2007 3:37 pm **Posts:** 9

First things first ... the exception is very clear .... however, I really believe that I have specified an @Id - but it's obviously not being recognized/located in the superclass. What am I missing or doing wrong? I'm using JBoss AS 4.2.1.GA with it's included hibernate version.

Please forgive the beginner question, but I've been searching for hours and keep coming up with the same Incomplete deployment error:

org.hibernate.AnnotationException: No identifier specified for entity: x.y.z.DefaultMyEvent

I'm also sorry if this is the wrong place for this question.

I'd appreciate any and all help as I am stuck!

TIA!

I have a base class such as:

Code:

@MappedSuperclass
public class DefaultEventBase
    implements IEventBase, Serializable
{

.....
    @Id
    @Column( name="ID", unique=true, nullable=false, updatable=false )
    public String getID()
    {
   return id_;
    }


.......
}

and a derived class such as:

Code:

@Entity
@Table( name="EVENTS", schema="foo",
   uniqueConstraints={@UniqueConstraint( columnNames="ID" )})
public class DefaultMyEvent
    extends DefaultEventBase
    implements ISMSEvent, Serializable
{

..... all other @Column definitions are here

}

I have a persistence.xml such as:

Code:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  
  <persistence-unit name = "foobar"
                  transaction-type = "JTA">
        
     <provider>org.hibernate.ejb.HibernatePersistence</provider>
     
     <jta-data-source>java:/MyDS</jta-data-source>
     
     <mapping-file>META-INF/orm.xml</mapping-file>

     <class>x.y.z.DefaultEventBase</class>     
     <class>x.y.z.PayloadItem</class>
     <class>x.y.z.DefaultMyEvent</class>
     
     <properties>
          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
          <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
          <property name="hibernate.format_sql" value="true"/>
     </properties>
  </persistence-unit>
</persistence> 

Finally, I have an empty orm.xml (as everything is specified via Annotations) such as:

Code:

<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm" version="1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm_1_0.xsd">
  
</entity-mappings>
