How to persist models entity in playframework submodule using jpa/hibernate

Question

I have project in PLAY FRAMEWORK wich contain few submodules.

Each submodule has folder structure like this:

• app:
  • controllers

Answer 1

I figure it out on my own.

Runtime error:

[IllegalArgumentException: Unknown entity: models.common.AppMode] Is caused by Jpa/Hibernate configuration. Problem is that Jpa/Hibernate sees my entities (mark by annotation @Entity) while compilation, but in runtime dosn't. To fix that I've to manually point all my models class (entitites) in persistance.xml file as follow:

/conf/META-INF/persistence.xml

    
        org.hibernate.ejb.HibernatePersistence
        DefaultDS
            models.common.AppMode
            models.Customer
            models.Complaint
        
            
            
            
        
    

Original post: package names (namespaces) in subproject classes in Play Framework

I wonder why in main project (f.e: /app/models/User.java) I can use annotation @javax.persistence.Entity (and it works), but in sub project (f.e: /modules/common/app/models/AppMode.java) it dosnt work, the annotation @javax.persistence.Entity is not enought, I have to point each model class in persistance.xml file.

I think it is a bug in playframework (I've checked 2.2.1, 2.2.4, and 2.3.4 versions)
