We've set the following property in persistence.xml:

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

```

If I understand correctly, this is what tells the OpenJPA MappingTool that it should generate appropriate tables in database, should those **not** be found for corresponding managed entities.

What I have failed to figure out is whether there is any way to specify the *ordering* of columns which MappingTool persists once it gets hold of reference to EntityManager?

MappingDefaults doesn't provide for such a property (at least I couldn't find it) and practically the only way to do this is to re-implement a part of OpenJPA API in order to support this.

That option is currently not feasible for us and I would ask for any idea or guideline on how to specify column ordering - if any.

Our environment consists of the following stack:

* OpenJPA 2.0.1
* JDK 1.6.23
* Spring 3.0.5
* Maven 2.2.1
* IBM DB2 9.7 Express-C

I am also a bit surprised that there only a handful of such questions on Google.
