+I would like to add some additional request here.
+
+A recurrent problem (at least for me but I suppose I am not the only one) when
using Hibernate API is that almost EVERY method can throw HibernateException
which is checked. Personnally I prefer to use checked exceptions only for
business, and unchecked (runtime) exception for "technical" problems. Hence
using Hibernate obliges me (and others) to put an infamous try{}catch(){throw
new RT;} in all my DAO methods!
+
+As far as I know in Spring framework, some "template" class (as it is called
in Spring) has been created to change HibernateException in most calls into a
Runtime exception.
+
+I think it would be good to offer the same kind of service in Hivemind.
+
+Unfortunately, I could not find any "powerful" way to implement that (in a
generic way by proxies, for instance). The fact is that MANY Hibernate
interfaces (SessionFactory, Session, Query, Criteria...) have methods throwing
HibernateException.
+
+This makes me better understand the way it has been implemented in Spring: one
Template class that combines all Session API + other common API from other
classes, but it seems to me that it reduces the possibilities of Hibernate for
the developer.
