ERROR: orml classes not found. Try generate java classes from a model

ERROR: orml classes not found.
The error is produced when I try generate java classes from a model. In the model I don’t specify any of database or orm parameters.

Someone can hep me?

Dear tintin,

Please create at least one class diagram that contains ORM Persistable class(es). In order to perform ORM code generation, you must have classes that are stereotyped as ORM Persistable. If you have an ERD now, please right-click on the ERD and select Synchronize to Class Diagram from the popup menu. This will create the ORM Persistable classes for you based on the ERD.

Best regards,
Jick
