Hello, Does anyone have a working Many to Many CMR example ?
Additionally, are there any words of advice as to how to implement a users & groups scheme for J2EE (JBoss) with XDoclet ? Here is what I have done and where I got stuck: I have the most standard Users and Groups configuration: User Table Group Table Permissions Table ---------- ----------- ------------------- USERNAME (PK) GROUPNAME (PK) USERNAME (references USER ) PASSWORD DESCRIPTIN GROUPNAME (references GROUP ) As per Ed Roman's "Mastering EJB 2" book, I decided to go with the approach of splitting my Many:Many CMR relation into 2 N:1 relations I have a User EJB, a Group EJB, and a Permission EJB , with an ejb.relation from User (1) to Permission (many) and an ejb.relation from Group (1) to Permission (many) all is well in my code, and when I deploy I get the database schema created exactly as desired. But here is where I got stuck : The code generated for UserCMP and GroupCMP creates a new PermissionLocal in each of their addPermission ( PermissionValue ) methods. So, I cannot possibly add the same Permission object to 2 different EJBs because they each will create a new row with the FK of the other set to NULL . So I'm wondering , how to do this ? I couldnt find any code examples of a M:N CMR with a mapping table using XDoclet. Any advice ? Am I going the wrong direction with this (very standard) problem ? Any other solutions for User-Group patterns in EJB ?
