Hi

I am pretty new with VP; i am using a floating standard licence of VP for UML

I have a ER diagram and now i want to generate an EBJ Diagram with the entity classes from the tables in the ER diagram

Is there any way to do this automatically ?? i have been searching but i cannot find any tool to do that;

thanks a lot for your help

Another thing, i tried to register in the forum and got this error

Thank you for your message and please refer to the following movie on how to create EJB diagram form your ERD.

And about the registration issue, may I know are you still not able to register to our forum?

Best regards,
