I dont believe i can let oracle > asign id's automatically like on mysql. Is there a solution to this problem? From what I gather Oracle complains about a missing primary key in the table m2m_196, right ? If that's the case, then there are two easy solutions that I can think of: * If the pair (ruleValueListId,ruleValueId) is unique in the table, then you can generate a composite primary key with these two columns. * Otherwise, you should define a sequence and add a new column to the table for the primary key. Something like this: http://www.lifeaftercoffee.com/2006/02/17/how-to-create-auto-increment-columns-in-oracle/ In this case, OJB will not have anything to do with the primary key of the m:n table.
