I try to perform testing on one-to-many unidirectional mapping for grails application on google app engine (GAE) using JPA. The one-to-many unidirectional mapping I attempt to define is between User and Role class. Unfortunately, I am stuck. Just curious is there any developer out there able to make it work successfully.
Following is my development environment:
- Windows XP Professional
- App Engine SDK 1.2.2
- Grails 1.1.1
- Plugins used: app-engine 0.8.3, gorm-jpa 0.5
