Subject Problem with database schema creation
Date Thu, 09 Sep 2010 17:38:18 GMT
  Please help a JPA primer

- JDK 1.6.0_21
- OpenJPA 2.0.1
- FirebirdSQL 2.1.3 + Jaybird 2.1.6

I manually created a new empty database.
I have only 1 entity :
-----------------------------------------------------------------------------
@Entity
public class ana_anagrafica implements Serializable {
     private static final long serialVersionUID = 1L;

     private Long id;

     @Id
     @GeneratedValue(strategy = 
GenerationType.SEQUENCE,generator="ANA_ANAGRAFICA_GEN")
     public Long getId() {
         return id;
     }

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

on persistence.xml :

<property name="openjpa.jdbc.SynchronizeMappings" 
value="buildSchema(ForeignKeys=true)"/>

but when i run the application I get the exception

1161  it.diegocattelan.ninphea-persistence  TRACE  [mod_BootModule_2]

if I manually create the sequence the error doesn't change.

Any hint ?
Thank you
