All;

The error is the "org.hibernate.LazyInitializationException " exception that we encounter, inspite of setting the "bankActlEstStatTypeCde" to "lazy=false". This application has been migrated from hibernate2 to 3.
I tried various combination but still the same error.
Please help. thank you in advance.

Debug level Hibernate log excerpt:
dont have this.

Code between session create and close.
I forgot to post this ....


Session sess = createSession();
estHist =(ArrayList) sess.createQuery(
"FROM BankActlEstStatHist as bankActlEstStatHist WHERE bankActlEstStatHist.bank.id = ? order by bankActlEstStatHist.bankActlEstStatAddDt")
.setParameter(0, bankId, Hibernate.INTEGER).list();
sess.close();


-Jenn

sorry for the cross post... but I think I need to open a new topic t discuss what I am confusion about ....

I was able to fix a smiliar problem in another relation within my project (a more trivial code) by actually settign the class atribute
"lazy=false" .

ie setting the "acmeinc.estimate.BankActlEstStatType" mapping with lazy=false.

now this fixes the problem but raises a new one. why do i have to decalre theis class as lazy="false" and shy it declaring its reference in the above mapping as "lazy=false" fix this.

Why do we have the lazy attibute in 2 places..

also read my other post with the same issue...
http://forum.hibernate.org/viewtopic.php?t=938806

-Jennifer

getting the following exception:
org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed
i have a many-to-many mapping table
have tried out lazy="false" which gives this exception.
lazy="true" also doesnt works

m working on hibernate3..plz help
