Hi,
In my DAO i have combined two tables and excecuted a query somethg like:
select object(obj) from POL pol,REQ req where pol.adc=req.adc and pol.inicd='133'

I have used EntityA having one to many relationship with EntityB like:
@OneToMany(mapped by="collection")
List<EntityB> ListInfo;
EntityB has ManyToOne relationship with EntityA(mapped by collection)
Now in the DAO i have executed the query. There is no exception. But while retrieving data from the List, i get
"SQLGrammerException:Could not initialize a Collection".

I am able to get values for EntityA but those List Values from EntityB could not be retrieved.

can anyone hlp me?
