[hibernate-dev] best approach to manage this many to many relationship

Hi, Want to implement a feature to allow a user to block a list of other users. The use case is for any given user id, find the list of users he blocks. I use a many-to-many relationship table to map the relationship: user1_id, user2_id Since there might be a huge long list of users a user want to block, I don't want to keep a list of blockedUsers inside my user data object. May even need to implement pagination to show the list of blocked users. What's the best way I can use Hibernate to maintain the relationship and answer query like: findBlockedUserListByUserId(userId). Should I use native SQL with addEntity? Is there a better way? If the same question has been asked, a pointer of that thread would help. thanks! Derek
