I need to be able to select with an IN query and a collection... something like this: | createQuery("from Campaign campaign where campaign.advertiser in (:advertisers) order by advertiserId").setParameterList("advertisers", selectedAdvertisers) | The EM doesn't support the setParameterList method. So instead I tried to create the query on an injected org.hibernate.Session object, but that generates the following exception: javax.resource.ResourceException: Transaction is not active: I am in a conversation, and the session object comes from this in components.xml: | <factory name="session" | scope="STATELESS" | auto-create="true" | value="#{entityManager.delegate}"/> | Am I barking up the wrong tree here?
