I have a UNIDIRECTIONAL ManyToMany Relationship between useres and usergroups. Users know their usergroups, usergroups don´t know their users.

I want to create a query to get all Usergroups which are referenced by a User with name 'john'

I tried:
select ug from UserGroup as ug, User as u join u.userGroupList where u.name = 'john' 
  | but got an empty result, what´s wrong?

  | public class User implements Serializable
  | { ...
  |   public String getName()
  |   @ManyToMany 
  |   public List<UserGroup> getUserGroupList()
  | @Entity
  | public class UserGroup implements Serializable
  | {	..
  | }
