Hi, I'm trying to decide whether to switch from having Hibernate sprinkled all over to using JPA2.0 and thus be provider portable. 1.Does JPA2.0 support custom user-types? 2.I'm on the verge of implementing Terracotta as a second-level cache to Hibernate with its clustering abilities mainly in mind. I would imagine, but I don't actually ...

It seems irritating that property paths that involve joins must be broken down into multiple criteria. This means that code building a HQL is considerably bloated especially when the path has many joins within it. I have been unable to find a library which "internally" expands paths into the right criteria. ...

Is there any way that Criteria for qureies can be built on a remote (Swing/SWT etc) client? We've been using the DetachedCriteria functionality in Hibernate for quite some time, but would like to use standard JPA 2. If not, could the code from hibernate be re-factored to create the remote API? Or is this something that might come alon...
Can we cache reference to EntityManager. As for our requirement, instead of injecting EntityManger into other EJBs, we are having utility class which will return the reference to entitymanager. The issue is each time we need to get reference, we are doing JNDI lookup. in order to avoid JNDI lookup, we want to cache the reference to ent...

I'm trying to map two objects to each other using a ManyToMany association, but for some reason when I use the mappedBy property, hibernate seems to be getting confused about exactly what I am mapping. The only odd thing about my mapping here is that the association is not done on a primary key field in one of the entries (the field is u...
