Hello,
In the following code, User and Role. When I tried to remove User, it will remove all the roles in the ROLE that the user has and also all the related records in the USER_ROLE_LINK. For example, User u = new User(); Role a = new Role("A"); Role b = new Role("B"); // persist a and b ArrayList roles = new ArrayList(); roles.add(a); roles.add(b); u.setRoles(roles); //persist u ..... em.remove(u); For the above codes, it wiil cause the problem that I described above. How can I only remove the User and the related records in the USER_ROLE_LINK when tried to remove a single user? And how can I remove all the users that a role have when remove a ROLE ? | public class User { | | ... | @ManyToMany (cascade=CascadeType.ALL, | mappedBy = "users", targetEntity = Role.class) | public Collection<Role> getRoles() { | return roles; | } | | ... | | } | | | public class Role { | ... | @ManyToMany (fetch = FetchType.EAGER, targetEntity = User.class, cascade=CascadeType.REMOVE) | @JoinTable (name = "USER_ROLE_LINK", joinColumns = { | @JoinColumn (name = "ROLENAME") | }, inverseJoinColumns = [EMAIL PROTECTED] (name = "USERNAME") | }) | public Collection<User> getUsers() { | return users; | } | | ... | } | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037370#4037370 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4037370 _______________________________________________ jboss-user mailing list [EMAIL PROTECTED] https://lists.jboss.org/mailman/listinfo/jboss-user
