The showing code cannot create such an exception AFAIK, you probably have some
other code somewhere.

Hi Emmanuel, you are great. Yes, the other codes in the Group class made the
exceptions. Now I fixed, but I have a new question. That is how to insert new
data into the joined table, e.g. add a new group into table
groups(group_id,...) and table group_members (group_id, account_id). Thank you
Hi Emmanul,
I got the insert method. Thank you so much.

select genre from Genre genre left outer join genre.movies
Set genres = new HashSet( query.getResultList );

Hi Emmanuel,
I also have a problem with manytomany query. Following are my codes:
public class Account {
| ...
| @ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE},
| fetch = FetchType.LAZY, mappedBy=accounts)
| public ListGroup getGroups() {
|
