Jon,

I've found this:

import org.hibernate.Session
import org.hibernate.SessionFactory
import org.springframework.orm.hibernate3.SessionFactoryUtils
import org.springframework.orm.hibernate3.SessionHolder
import org.springframework.transaction.support.TransactionSynchronizationManager
sessionFactory = ctx.getBean("sessionFactory")
session = SessionFactoryUtils.getSession(sessionFactory, true)
TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session))

I've tried to load some collections on shell and worked.

Try it see if it works w/ you.

This should work in the groovy console, the shell has a problem since
it was migrated to the new syntax highlighted one that means the
events aren't fired (which attach a hibernate session to each command)

Cheers
