NHibernate Class-to-mappings template?

I have seen several NHibernate templates here and elsewhere that will generate classes and mappings from a database. But I'm looking for the reverse. I develop my business objects first, so I'm looking for a template that will use a business model to generate mapping files and a database script.

Is there a template, either here or elsewhere, that will do that? Thanks in advance for your help.

 Although there may possibly be one using reflection (assuming you didnt create a schema definition), you're really walking into murky water if you go this route, please let me explain - although the spirit of what you are doing is correct ie: identify your problem domain, and analize your data requirements first - you need to realize that how the data actully gets stored and accessed can't be determined from your class structure alone.  a table containing contact information, how long should FirstName be allocated for? should it only allow unique values? etc.

its possible to generate hbm.xml from the code .. its possible and its helpful ...

yes .. right ... not all the information is available because of the database table and column names ... but it would be good for me to have all my hbms generated with empty "" for the not available schema data ...

is there a template for this ?

I'm also very interrested by a such template. I also first writte my business objects and then the mapping file. Did you find a good one ?
