I try to access wqsite set on the many-to-one relation above. I have lazy="false" but still get the error. I thought with lazy="false" all objects assoiciated are loaded completely. Any hints, I read the documentation and thought it states that I should have objects loaded when specifying lazy="false"

Thank You and forgive me if I am stupidly miss-understanding some obvious facts. I use hibernate 3.0

I believe you need to also turn off proxies for the Wqsite class. Set lazy="false" on the <class> tag for gov.noaa.nwfsc.omi.sdm.wqbemp.hibernate.model.Wqsite.

What does your application code look like ?

try to use

Hibernate.initialize(item.getWqsites());
