With XML, we could generate id using IDENTITY

<id name="id" attribute-type="Integer">
<column name="id" />
<generated-value strategy="IDENTITY" />
</id>

How could we achieve this using Dynamic API?

JPADynamicTypeBuilder typeBuilder = dynamicTypeBuilders.get(entityMeta.getName());
...
typeBuilder.setPrimaryKeyFields(pkColumn);
NativeSequence seq = new NativeSequence();
seq.setShouldAcquireValueAfterInsert(true); // not working

Thanks!

Did I clearly show my situations?

I just want to specify the id of the entity using dynamic API of EclipseLink JPA. And I want to specify the generated-value strategy of it. For Mysql, I intend to use auto-increment(IDENTITY strategy). Using annotations/XML, we could do it easily. But how to do with dynamic API?
