1. )Where can I find a list of all the issues/shortcomings in "hbm2hbmxml"
along with suggestions on how best it can be fixed?

For example where it should make one-2-one relationships its making only many-2-one.

2.) What is the best way to parse and manipulate hbm files?

3.) How can one change the logic used by "hbm2hbmxml" by extending it so that it can do the one-2-one relationships ?

is it possible to extend "hbm2hbmxml" and use some internal wrapper api over jdbc database metadata to do do the work of "hbm2hbmxml" properly?

So why don't you fix it in the templates ? :)



not sure what you mean but hibernate is what we used to parse the hbm.xml files and then we use freemarker as a templating language to generate code from it.



probably just a matter of fixing the relevant *.hbm.ftl file in hibernate tools.
