Jesper, these are exactly the same problems I was dealing with when figuring out how to make stuff work with Ironjacamar a couple months ago. I'm pretty disappointed to see they're still happening.
The code generator "works" only after you tweak a lot of the output, and trying to figure out all the setup leading up to there is pretty difficult. The project documentation is very opaque, and I find myself storing virtually every "known working" artifact I create somewhere in source control just as a reference.
Murray, I feel your pain.
