I was writing some JPA code (Hibernate implementation) that used
and kept getting this when I ran the webapp in Tomcat:
nested exception is org.hibernate.cfg.NotYetImplementedException: Pure
native scalar queries are not yet supported
The exception was from an unrelated class but I suspected that this
was caused by changes I made.
According to this:
resultClass is required for all NamedNativeQuery, even the ones that
don't return them, because of a longstanding BUG in Hibernate.
Apparently the bug was fixed as of Hibernate 4.2 but we're still on
3.6 so upgrading is not really an option.
