My table structure is like this:

USERS -> user_id , user_nm
GROUP_MAP -> user_id, group_id , perm_id(this field is assign permission for user_id and grou_id combination)
GROUPS -> group_id , group_nm

The asscociation in my USERS.JAVA POJO is

@ManyToMany(cascade = CascadeType.ALL)
@ForeignKey(name = "FK_USER_ID", inverseName = "FK_GROUP_ID")
@JoinTable(name = "GROUP_MAP", joinColumns = {@JoinColumn(name = "USER_ID")},
inverseJoinColumns = {@JoinColumn(name = "GROUP_ID")})
public List<User> getUsers() {
return users;
}
public void setUsers(List<User> users) {
this.users = users;
}

How do I insert values into the perm_id column when I insert groups.
Thanks for help
