Hibernate code generation adds unexpected @Version?

Hello all,

I'm using eclipse 3.5 and hibernate tools v3.2.4 to generate JPA annotated entites from a SQL Server 2008 database using MS sqljdbc4.jar JDBC driver.

For some reason on one column hibernate code generation allways generates @Version annotation:

Code:

   @Version
   @Temporal(TemporalType.DATE)
   @Column(name = "Timestamp", nullable = false)
   public Date getTimestamp() {
      return this.timestamp;
   }

Column "Timestamp" is designed with SQL Server 2008 type "date" on db server side.

I also have a type-mapping defined for this column in my hibernate.reveng.xml file:

Code:

   <table catalog="catalog" schema="dbo" name="Table" class="db.Table">
      <primary-key>
         <generator class="identity"></generator>
      </primary-key>
      <column name="Timestamp" jdbc-type="NVARCHAR" type="date"></column>
   </table>

Is there a way to prevent generation of @Version attribute ?

Why does it get generated in the first place (am I doing something wrong) ?

Regards,

Mario

disable auto optimistic locking detection and it won't look at it.

You can also customize the detection in a custom reverse engineering strategy if you wish.
