I have 3 tables:
tbl_movie
Code:
id
name
...
tbl_theaterCode:
id
name
adress
...
tbl_eventCode:
id
movie_id
even_id
price
date
....
and I have 3 corresponding classes, Movie, Theater and Event
What I'm trying to do is to make sure
everytime I load a Movie, it comes with set of theaters it plays in, and vice versa for Theater.
So basically, everytime a Movie is loaded, find the mapping entries in the
tbl_event and through those records load the Theater objects.
In Theater I have:
Code:
List movies
and Theater.hbm.xml contains:
Code:
<bag
name="movies"
table="tbl_event"
lazy="false"
inverse="false"
cascade="none"
>
<key
column="theater_id"
>
</key>
<element
column="movie_id"
type="Movie"
not-null="false"
unique="false"
/>
</bag>
and in Movie similarly:
Code:
List theaters
and the Movie.hbm.xml contains:
Code:
<bag
name="theaters"
table="tbl_event"
lazy="false"
inverse="false"
cascade="none"
>
<key
column="movie_id"
>
</key>
<element
column="theater_id"
type="Venue"
not-null="false"
unique="false"
/>
</bag>
When I try to load the Theaters, say, by their zipcode:
Code:
Query query = session.createQuery("from " + Theater.class.getName()
+ " venue where theater.address.postcode like :zip "
+ " order by theater.address.postcode, " + " theater.name");
query.setParameter(...,...);
I get the following error:

All classes implement Serializable and have default constructors...
What am I doing wrong here?
Thanks in advance,
