Description manu206 2015-07-13 16:06:33 UTC 
I'm using jpa with netbeans "Entity classes from database" function to generate my entity classes. Sadly, netbeans chooses the wrong manytomany relationship owner. I have for example a user and group table which are related via many to many. In my case the group entity is the owner with @JoinTable and User has the "MappedBy" annotation. How can I make User to the owning entity. I could change it manually but after generating it again from database, it will be overwritten. This is really annoying. Any ideas?

My n:m table has userId as first column and groupId as second. I assumed that this order will determine owning side?!?
