What are the pre-requisites to get a many to many mapping with the EJB3 "Generate Persistence Mapping Tool"?
The okay button seems grayed out every time I try to map a many-to many relationship.
Please see the attached picture for the database layout, etc...

MySQL tables seem to need to be of type "innodb". Seems to fix the issue.

The screenshot shows that JoinColumns are not set for the JoinTable.
