I'm using JBuilder 8 and the version of Tomcat it comes with: 4.1.12,
which could use updating, but hey.
I've declared in JBuilder "Library" definitions for each of the
Hibernate Distributions. They are below. I've trimmed some out of the
Hibernate 2.1.2 definition to rule out things, but I think you'll see
there aren't mismatches.
When I switch between these hibernate libraries, I do a Make Clean, I
make absolutely certain my .war file is gone, I recompile and go from
there. It's *real* consistent. In fact, when it has worked when I didn't
expect it to (or vice versa), I inevitably double check to find it was
my mistake in the rebuild/restart process.
My theory right now is something in commons struts uses isn't the same
rev as what Hibernate does.
Library defs follow:
