How to apply creation timestamp with

[Marcel Ruff]

Hi,

i need to set for Postgres 8.3.x on new table entry creation a timestamp 
and have tried this:

   @Column(name = "creationts", columnDefinition="timestamp not null 
default current_timestamp")
   public java.sql.Timestamp getCreationTs() {  return creationTs; }

The dll applied to Postgres directly works fine and creates the 
timestamp during insert on the fly.

Using openJpa i get:

 org.apache.openjpa.persistence.PersistenceException: ERROR: null value 
in column "creationts" violates not-null constraint

what can i do?

Thanks
Marcel
