The problem is that you're trying persist an Entity(model) that has a relationship to another Entity(catalog) that is from a different persistence unit. From the model-persistence persistence unit's point of view, the catalog that is referenced by your model is a non-persistent field. I'm reaching a bit here, but I think you have two options. Either compress down to one persistence unit, or mark model->catalog as @Transient so that relationship will be ignored by OpenJPA.
